In this article, I will show you to how to value a company using the discounted cash flow model (DCF), and will guide you through a complete DCF valuation for a real company on the stock market. By doing so, we'll be able to estimate the company's intrinsic value, which will tell us whether the current stock price is undervalued or overvalued.
The intrinsic value, also known as the fair value, can be defined as the value today of all expected free cash flows from the future. Knowing a company's intrinsic value is useful for value investors who want to purchase companies at attractive (undervalued) prices in hopes of future investment gains.
The formula to find intrinsic value is below:
Intrinsic value = [FCF1 / (1+r)1] + [FCF2 / (1+r)2] + .... + [FCFn / (1+r)n] + [FCFn * (1+g) / (r - g)]
To find the intrinsic value of a business, one of the best ways is to use a DCF valuation. With a DCF, you will value any asset based upon its intrinsic characteristics, the asset's expected cash flows over its lifetime, and the uncertainty on receiving these cash flows. Therefore, by completing a DCF valuation you will follow the principal that the value of a company can be derived from the present value (PV) of its projected free cash flow (FCF).
The 8 steps to completing a DCF valuation are listed below (and on the table of contents), and will be covered after the next section.
The DCF stock valuation method is a widely accepted and respected method in the world of finance. Although investors have to make a number of assumptions when completing a DCF analysis, if investors value the right companies, are conservative with their numbers, understand how to apply sensitivity analysis and a margin of safety, and avoid bias (which is all easier said then done), they may be able to accurately value these companies and profit significantly over the long-term.
Therefore, as investors the DCF model should be utilized for long-term investment opportunities. However, the intrinsic value figure you find should never be looked at independently as it never tells the complete story of a company and what its stock price may be worth. In other words, investors should also look at the company's competitive advantage (economic moat), its management team, how the company manages debt, and many other financial and non-financial variables to really determine the price range they would be willing to purchase the company for.
With this in mind, when is a DCF valuation the most viable?
Put simply, the DCF model works when companies have free cash flow (FCF) and when FCF can be reasonably estimated. FCF measures how much cash is available to companies after repaying creditors or paying dividends and interest to investors.
Therefore, early-stage companies are likely not a good candidate for a DCF as they may have high growth but limited amounts of FCF in their current state. It's also difficult to accurately value companies that are cyclical due to the nature of their business. On the other hand, large blue-chip companies that are more established are typically perfect for a DCF analysis.
Now, as a general rule, if any one of the four criteria below are met, the company is a viable candidate from a valuation perspective because it has free cash flow (FCF):
Follow the criteria above to the best of your ability to determine whether a DCF valuation can be applied to the company you may be looking to invest in. It's also wise to stick with more established companies as their capital expenditures (CapEx) and FCF may be reasonably estimated, although this differs between companies and industries. Therefore, it's a good idea to have a thorough understanding of a company (i.e., its business model, competitors, where its revenue sources are, etc.) before completing a DCF valuation for a company.
The company I'll be doing a DCF valuation on is Intel Corporation (INTC), a market leader in manufacturing and developing computer microprocessors and chip-sets.
You can see Intel's stock price performance overtime in the chart below:
Intel has a current market cap of over 212 billion, has a rather low dividend yield, and is a blue-chip stock. Therefore, a DCF analysis will clearly work well for this company as it meets more than one of the four criteria above. Moreover, the company has FCF and we can reasonably estimate FCF over the next 5 years at the very least.
Now, follow the steps laid out in this article to see how I found the intrinsic value of Intel. But before I begin, make sure you know how to read and access the 10-K's for the company you're analyzing. You can also use a financial data website like QuickFS to reduce the amount of time spent looking through financial statements and 10-K's.
The first step in a DCF analysis is to find the free cash flow (FCF) for a company. FCF measures a company's financial performance and shows the amount of cash a company has remaining after accounting for operating expenses and capital expenditures (CapEx). In other words, FCF is the amount of cash flow available for discretionary spending by management and shareholders.
There are two types of FCF calculations:
The primary difference between FCFF and FCFE is interest payments and taxes, as FCFE includes interest expense paid on debt and net debt issued or repaid.
In most DCF valuations, you'll want to use FCFE because it provide a more accurate picture of firm sustenance. FCFE is also ideal as long as the leverage for the company you're analyzing is fairly stable.
So, use FCFE unless the firm's capital structure is expected to change in the near future, for example because of the company taking on a lot more debt. On a side note, if FCFE or FCFF is expected to be negative in the foreseeable future, then you picked the wrong company for a DCF valuation.
Because I'm attempting to find the intrinsic value of Intel, a company with a fairly stable capital structure, I will use the FCFE approach to calculate and estimate Intel's FCF.
Some analysts choose to use the simple FCF figure as it's very difficult to predict the net borrowing a company will have in the future, when we forecast free cash flow.
Below is the simple and most commonly used FCF formula approach:
FCF (simple) = Cash flow from operations - CapEx
The first thing you need when analyzing FCF is cash flow from operations, found in the cash flow statement. Then, you would subtract total capital expenditures (CapEx), also called the plant, property and equipment (PP&E) under the investing section on the cash flow statement. This would give you the simple FCF figure.
Doing this for Intel gives me the following FCF numbers:
This is the approach many wall street analysts take, primarily because it's difficult to predict when a company has "net borrowings" in the future.
Technically, you should add back any "net borrowings," or money borrowed for financing activities in a business (found under the financing activities in the cash flow statement). In Intel's case, this line item is called "Net Issuance of Debt." It's also the difference between the total debt issued and the total debt paid over a period.
FCF = (Cash flow from operations - CapEx) + Net borrowings
You would add net borrowings to account for any debt the company took out. Sometimes, this can change the FCF figure significantly.
This is shown below for Intel:
Now, if we compare the difference in FCF after adding net borrowings, we can see just how much this fluctuates year-over-year:
Calculating FCF with net borrowings is the more accurate method of finding FCF, because you're factoring in any money borrowed by the company which may affect the cash available to shareholders. However, because net borrowings is difficult to predict accurately, I would recommend that most investors stick with the simple FCF approach and ignore net borrowings altogether. There are also other ways of calculating FCF, but they more or less lead to the same result.
After you have your FCF figures, you must forecast how much this will grow in the next 5 or 10 years typically, but this all depends on the company you're valuing and your preference. In our case, I will go with the standard 5-year forecast period.
The table below may provide you with an idea of a company's competitive position and what forecast period you should use for a DCF valuation:
This is a table you can refer to when deciding on the forecast period for your company's FCF. If you're unsure on how many years to forecast FCF, stick to 5 years. If you decide on projecting FCF 10 years (or even longer), just know that the further these numbers are projected out, the more these later periods are subject to estimation error. Moreover, these later FCF figures may be completely inaccurate, simply due to the uncertainty the future holds.
Now, there are various ways to forecast your FCF, but I will show a simple and effective method that works well.
I will begin by finding how much FCFE (same as FCF) aligns with profitability by using the approach below:
FCFE rate = FCFE / Net income
This will give me a percentage, and the closer this is to 100%, the more the FCFE aligns with profitability. This is also one of the four criteria for deciding on whether a DCF can be used for a company. I will then use the figure I think best represents a company's FCF's, relative to net income over the past years, and estimate future cash flows afterwards.
In the table above, we can see that the FCFE rates for the past 5 years are more or less about equal to net income (close to 100%), with more deviation over the last 2 years.
The percentage you choose to use here depends on your research of the company and how different you think FCFE will be relative to net income over your forecast period. If you're not certain on the company's future, you can use the smallest percentage (if it's not an outlier) to be conservative. If you decide to use a higher percentage, it would make your estimates more aggressive.
Based on my research and knowledge on Intel, and because I want to be conservative, I will choose to use 80.44% as the FCFE rate.
The next step to determine future FCF is to forecast revenue which will lead us into net income and then come up with FCF afterwards. You could also forecast net income and then derive FCF off this. However, I'll show the longer FCF revenue approach.
For a large company like Intel, there will be many analysts covering the company and giving their estimates. One common way of finding revenue estimates is to use Yahoo Finance, search your company, and then go to the "Analysis " tab. From there, you can see what analysts estimate for revenue over the next few years, along with the number of analysts as well:
In the image above pulled from Yahoo Finance, we can see the revenue estimates for 2020 and 2021 are $75.13B and $73.46B respectively, both with a good analyst sample size. I will use these figures as Intel's revenue estimates for 2020 and 2021.
If you're valuing a company that does not have a revenue (or net income) estimate, or perhaps too few analysts for the estimate to be considered reliable, you can choose to identify a reasonable growth rate for the company instead. You must do this anyways to project a company's revenues to the end of your forecast growth period.
One method to determine this growth rate is to find the revenue growth rate between each year, which is just the percent difference between any two consecutive years:
Revenue growth rate = (New year - Old year) / Old Year
Then, you can simply average the forecast revenue growth rate (for 2020 and 2021 in our case), or use the average revenue growth rate for the past 5 years to come up with a reasonable revenue growth rate. Afterwards, you would apply this rate to the rest of your forecast growth period.
In Intel's case, this would be 1.09% if I were to average the next 2 years (2020 and 2021) or 4.46% if I were to use 5 years instead (including 2020 and 2021). The growth rate you select will be dependent on you and how you think the company will perform in the future.
In my case, I will choose to use 4.46% as the revenue growth rate and apply this revenue growth to 2022, 2023, and 2024. If I did not have reliable revenue estimates for 2020 and 2021 from a source such as Yahoo!Finance, I would've began with 2020 instead.
The revenue and revenue growth rates for Intel are shown below:
The important thing here is that you use a revenue growth rate that makes sense, which is where your understanding of the business plays a large role in. So, a large and established company will likely have a smaller growth rate than an early-stage company with more growth potential.
Moreover, the further you project a company's revenue growth, the more uncertain its revenue will become, simply because the future is impossible to predict. So, if you have a forecast growth period of 10 years instead of 5 like I'm doing, using a smaller and more conservative revenue growth rate figure may be smart.
Now that you have revenue projections, the next step would be to find net income. One method is to find "net profit margins," which determines the proportional profitability of a business, expressed as a percentage of revenues:
Net profit margin = Net income / Revenue
Net income and revenue are found on the income statement. Doing this for Intel from 2015-2019 gives me the net profit margins below:
If I average out these 5 years, I'll get 22.45% net profit margins for Intel, which will then be used over the forecast growth period to come up with future net income (by multiplying it to the projected revenue figures), as shown below. Again, you can also use a lower percentage if you want to be more conservative.
This will get you the projected net income figures, in this case for 2020-2024.
Next, take your FCFE rate found before (80.44%) and multiply this by net income to get projected FCF, or over the next 5 years in our case:
Finally, we can enter these FCF numbers we just found into our DCF calculation, and this completes step 1.
Note that you can also calculate a figure called "owners earnings" each year, favored by Warren Buffett, and use this to replace the FCF figures found above. However, this can be even more involved, but can provide you with a potentially more accurate valuation.
The next step is to calculate the discount rate, or required rate of return. The required rate of return is the minimum return an investor will accept for owning stock in a company, accounting for the risk of holding the stock. Because we're using FCFE, our discount rate should be based on our individual perspectives as an investor.
Therefore, the required rate of return I prefer using will most likely be different than yours, simply because the return I require on the companies I purchase may be higher or lower than yours. In other words, my required rate of return will differ from yours because of the differences in our risk tolerance, investment goals, time horizon, and available capital, among other things.
So, if you've done valuation before and know a required rate of return that works for you, then use this. However, if you don't have a personal required rate of return, then we can go through a more involved process and come up with a basic required rate of return using the "weighted average cost of capital" (WACC), which is essentially a default required rate of return.
Typically, it would be the company that would use a WACC and apply this to the FCFF, not to FCFE. Regardless, the WACC can still be used in a DCF valuation.
Personally, I try to avoid using the WACC because it relies on an asset-pricing model called the "capital asset pricing model" (CAPM), which comes with a number of assumptions. The main issue with this model for valuation, is that it assumes investors act rationally on the latest available public data and that markets are efficient, which is obviously not true in the stock market. So, to use the asset-pricing model in this regard may lead to misleading figures in your valuation.
That being said, the WACC is still the next-best alternative if you do not have a personal required rate of return. I will also use the WACC found below for Intel in this article because I cannot apply my required rate of return to every investor.
The formula below is how you can calculate WACC for any company:
WACC = wd * rd (1 - t) + we * re
Now, let's begin by finding the first part of the formula, the debt portion.
The cost of debt (rd) is the market/actual interest rate the company is currently paying on its obligations. I will show you two methods of estimating the cost of debt, but the second method can only be used if your company did not issue a lot of debt (net borrowings) in its current year.
The method I prefer using when I'm building models is the debt rating approach, where you are simply adding the company's default spread (depending on its credit rating) to the current risk-free rate. Then, you'd multiply by one minus the effective tax rate:
rd = (rf + default spread) * (1 - t)
The risk-free rate is the 10-year treasury yield figure, and is the rate of return an investor would expect to receive from an absolutely risk-free investment. This rate changes daily, so use the most recent date from the USDT website.
As of writing, the risk-free rate is 0.85%, so I will use this.
The default spread is the difference between the yields of two bonds with different credit ratings, and a bond's credit rating is just a letter-based credit score used to judge the quality and creditworthiness of a bond. So, an investment grade bond like "AAA" will have a lower default spread and will be considered safer than any bond rated lower, such as "BBB."
Before you determine the default spread, you first have to find the company's credit rating through Moody's, Morningstar, or FitchRatings (among others), and determine what rating the company has.
See my dividend investing article to learn more about credit ratings, view a credit ratings table, and know how to find credit ratings.
Currently, according to S&P Global Ratings, Intel has a credit rating of A+ or A1, depending on the agency.
Then, we can use a default spread table to determine the cost of debt, using a default spread table and the formula shown above. However, because it's difficult to find an up-to-date, free, and accurate default spread table, the next-best option is to estimate a synthetic rating instead.
You can use the table the below for "developed market firms with market cap > $5 billion," which is based on the interest coverage ratio:
Interest coverage ratio (ICR) = EBIT / Interest expense
The thing to keep in mind with this table is that default spreads will fluctuate due to changes in the market (inflation, liquidity, demand, etc). Therefore, it's in good practice to use an updated table.
Intel's interest coverage ratio is 45.87 (22,428 / 489), so according to this table it would be classified as a AAA bond with a default spread of 0.63%. However, we know the actual current rating is A1/A+, so we can go with the middle-ground and select 0.78% as the default spread.
Then, if we add 0.78% to the risk-free rate of 0.85%, we will come up with Intel's before-tax cost of debt of 1.63%. However, in most countries, interest expense is a tax-deductible item, meaning companies will pay less in taxes due to these interest payments. Therefore, this 1.63% is not the true cost of debt, and we have to use the (1 - t) in the WACC formula to find the actual after-tax cost of debt.
To find the tax rate (t), find it on the company's most recent 10-K annual report or use the following formula with figures found on the income statement:
Tax rate = Income tax expense / Income before tax (EBT)
Doing so for Intel will give us an effective tax rate of 12.51% (3010 / 24,058), which we can also compare to the tax rate on the company's 10-K annual report to double-check. This is usually found in the "Notes to Financial Statements" section on the 10-K:
As you can see, this effective tax rate is also 12.51% (just rounded), so we can compute the actual (after-tax) cost of debt now:
rd (debt rating approach) = (0.85% + 0.78%) * (1 - 12.51%) --> 1.4261%
One quick method to find the company's cost of debt is to take the company's average annual interest expense and compare this to the company's total debt (short-term debt + long-term debt). Again, this method only works if the company did not issue a lot of debt (net borrowings) in its current year:
rd = (Interest expense / Total debt) * (1 - t)
For Intel, it only had $765 million in net borrowings (we found this earlier), so this method should work, and is shown below using figures from the income statement and balance sheet:
As the previous method covers, this is the before-tax cost of debt, and we must apply the effective tax rate of 12.51% we found before to compute the actual (after-tax) cost of debt:
rd (interest expense to total debt approach) = (489 / 29,001) * (1 - 12.51%) --> 1.4786%
Both approaches resulted in roughly the same answer for Intel's cost of debt, although this obviously is not always the case. Moreover, because method 1 has more variability to it, and because Intel does not have a lot in net borrowings, I will choose to use the result from method 2 (1.4786%) to compute the WACC later on.
The next step is to calculate the cost of equity (re). To do this, use the capital asset pricing model (CAPM), which describes the relationship between systematic risk (β) and expected return (re) for stocks:
re = rf + β*(rm - rf)
We already found the risk-free rate (rf) before, using the USDT website. Again, this is the current 10-year U.S. treasury bond rate, which as of writing is 0.85%.
Next, you should find the beta (β) of the stock, which is simply a measure of the volatility or systematic risk of the company when compared to the market as a whole. So, a higher beta number means higher risk and higher return potential.
For Intel, I found its beta by going back to Intel's Yahoo! Finance page, selecting the "Statistics" tab, and using the "Beta (5Y Monthly)" 0.72 number.
Now, we need to find the expected return of the market (rm). One method is to find the average annual return going back 10, 15, 20, or more years using whatever financial data website you'd like. However, I like to use 10% as it's generally the average annual return of the S&P 500 Index since its inception in 1926. If you use this 10%, you may want to adjust this figure slightly (even if it's only by 0.5-1%) depending on the current market condition, or if you have good reason to believe this will be lower or higher in the near future.
Plugging all of these variables in will get us the cost of equity for Intel below, which we can then use in our WACC equation:
re (INTC) = 0.85% + 0.72*(10% - 0.85%) --> 7.438%
The final parts of the WACC formula is to find the weights of debt and equity.
To do this, take the total market cap of your company (found on Yahoo Finance), which represents equity, and the total debt, and add them together. Then, determine how much of debt and equity consists of this total figure by simply dividing them as shown below for Intel:
As you can see, the we is 87.20% and the wd is 12.80%. We can then use these figures to finally solve for Intel's WACC, which will then be used as our discount rate in our DCF valuation.
WACC (INTC) = (12.80% * 1.4786%) + (87.20% * 7.438%) --> 6.68%
You can then plug this 6.68% figure into your DCF spreadsheet as the discount rate (required rate of return), and this completes step 2. For another example on how to calculate the WACC (with downloadable spreadsheets), see the link below:
The perpetual, or constant growth rate, is the growth rate that free cash flow (FCF) is going to grow at, forever.
Personally, I use a perpetual growth rate between 0-2.5% depending on the company and the market. This conservative range is about in line with the expected growth of the U.S. economy, the inflation rate, or long-term GDP growth.
The important thing here is to not use a growth rate that is too high, like 5%. If the economy is growing at 3% and we use a 5% growth rate, we're essentially implying that one day, even if it never happens, the company will be larger than the economy, which is absurd. So, the growth rate that you're using to project into infinity forever (g) needs to be smaller than your discount rate (r), in our case 6.68%.
For Intel, I will be more on the aggressive side and go with use a perpetual growth rate of 2.5%. You will use this perpetual growth rate percentage in the next step when solving for terminal value.
Terminal value (TV) is the value of a business beyond the forecast growth period for when future cash flows can be reasonably estimated, as you cannot estimate cash flows forever. By finding the terminal value, investors can estimate what the cash flows will be after the forecast growth period, which in our case is after 5 years.
One formula to calculate terminal value is below:
TV= FCF * (1 + g) / (r - g)
So, to find terminal value, you'd take the last forecast time period, in our case time period 5, and you'd grow this (FCF5) one year by your perpetual growth rate that you found earlier. This would give you the free cash flow for time period 6.
Then, you would divide this figure by your required rate of return (or the WACC) minus the perpetual growth rate.
This entire process is shown below for Intel, where I'm using a perpetual growth rate of 2.5% and the WACC of 6.68%:
TV= $15,124.57 * (1 + 2.5%) / (6.68% - 2.5%) --> $371,321.80
So, this $371,321.80 (rounded) is Intel's terminal value at the end of period 5, or the beginning of period 6.
The next step is to find the number of shares outstanding for the company, which is the amount of company stock held by all shareholders, including insiders and institutional investors.
Going back to Yahoo Finance, we can see that Intel has 4.1B currently in shares outstanding.
To find a more exact figure, you can look at the company's most recent 10-K annual report or 10-Q quarterly report to find the number of shares outstanding. This is typically found on the cover page as shown below for Intel's most recent 10-Q:
So, Intel had 4.098B in shares outstanding, which we will later use to compute the intrinsic value of the stock.
Now, one of the most important steps in a DCF calculation is to account for the time value of money (TVM), which states that a dollar today is worth more than a dollar in the future due to its potential earning capacity. Therefore, you must discount any money you project into the future to find the present value figures, which you can then use in a DCF calculation.
This would be done by using the approach below:
PV of FCF = FCF / (1 + r)n
So, begin by finding the discount factor (the denominator) for each period, including the terminal value figure we just calculated.
For example, for the forecast FCF3 (2022 in our case), you would do: (1 + 6.6752%)3, which would give you the discount factor for 2022. Then, you'd take the forecast FCF3 you found in step 1, and divide by this discount factor to solve for the present value of the free cash flow figure (PV of FCF) for the forecast year of 2022.
In our case for Intel with a 5-year forecast period, you'd do this six times, but the sixth time with terminal value you'd use the 5-year time period instead (n).
After this is complete, you would sum up all of these PV of FCF figures to come up with today's equity value.
Finally, you would take today's equity value and divide it by the total shares outstanding (found in step 5) to get the intrinsic stock value of Intel today at $79.63.
This entire process for step 6 is shown below for Intel:
So, based purely on this DCF and not factoring in a margin of safety or doing any sensitivity analysis (as later discussed), Intel's current stock price (around $45) is undervalued because it's less than our fair value of equity (intrinsic value) of $79.73. Therefore, ignoring everything else (the market, the company, news, etc.), you should purchase Intel stock.
As mentioned in the beginning of this article, there are holes in using a DCF valuation to find a company's intrinsic value. This is primarily due to the number of assumptions you have to make when coming up with a company's intrinsic value. But as you know, if we're conservative with our figures and estimates throughout the DCF process, we can generally come up with accurate intrinsic values.
Now, the whole DCF calculation is very sensitive to the inputs that go into coming up with intrinsic value. So, if I changed the perpetual growth rate or opted into using my personal required rate of return in particular, this would change things significantly.
This is why you should always do a sensitivity/scenario analysis after completing a DCF calculation. Doing so will allow you to see how these changes impact things and will allow you to pick the most conservative number.
For example, in our case if I wanted to be even more conservative, I would use a lower perpetual growth rate or an even lower required rate of return (which is already low to begin with). And, if I wanted to be more aggressive, I could keep the perpetual growth rate the same but change the computed WACC discount rate to my personal required rate of return, which would drop the intrinsic value price significantly.
A basic sensitivity analysis for Intel is shown above, where I'm using discount rates from 6-15% to find the fair value of equity (intrinsic value). I'm also using the perpetual growth rate of 2.5% we found before and comparing this to a more conservative 1% perpetual growth rate. This causes the intrinsic value price to fall and gives me an idea of the price I may be willing to pay for Intel if I expect slower perpetual cash flow growth.
As a final note, if you change assumptions incrementally, such as the discount rate or growth rates as I previously did, a healthy DCF model will reflect this through incremental changes to its intrinsic value. However, an incorrect DCF model will not reflect these incremental changes, and a 0.5-1% change to your discount rate, for example, may result in significant changes to your entire DCF model and buy-price. If this happens to you, you're depending way too much on your discount rate and therefore your model may be incorrect.
So, by completing a sensitivity/scenario analysis, you can also check to see whether incremental changes to assumptions in your DCF model are outputting reasonable incremental changes to your intrinsic value. If not, then revisit the previous steps and attempt to find why this is the case.
After you have an intrinsic value of the stock and have completed a sensitivity analysis, you should have a range of stock prices you'd be willing to purchase the company for. This would depend on your required rate of return and your understanding of the business.
The final step would therefore be to place our own personal margin of safety to these numbers, or in our case, just the intrinsic value figure we found before for Intel ($79.63) with the WACC of 6.68%.
You always want to apply a margin of safety because of the following two main reasons:
So, by applying a margin of safety, you will account for errors in your valuation and market uncertainties, which may also prevent you from purchasing companies that are actually overvalued. This will provide you with more confidence when the stock finally falls within your buy-price range, as you'll be purchasing it far below its intrinsic value price.
Naturally, the more confident you are, the smaller the margin of safety will be. On the other hand, the less confident you are in your valuation, the larger the margin of safety. This goes hand-in-hand with risk, with riskier investments intuitively having a larger margin of safety than safer investments.
Below is a rough margin of safety table you can refer to depending on the confidence you have in your DCF valuation, which is purely subjective:
Note that these margin of safety rates differ between investors, and that for lower discount rates a higher margin of safety should apply. So, even if you have high confidence in your DCF valuation but are using a low discount rate (i.e., < 10%), it may be wise to use a discount rate of 20%+. Moreover, for valuation beginners who may overestimate growth rates, I would recommend going with a larger margin of safety which would drive down your intrinsic value buy price(s).
In short, it's wise to have a flexible margin of safety measure that you can vary across different investments. Doing so, while accounting for your confidence level, the risk level of the security, and the discount rate you used will provide you with a reasonable margin of safety that you can then apply to your intrinsic value buy-price.
Below, you can see how the actual intrinsic value buy price varies when we apply discount rates from 10-30% with our intrinsic value per share of $79.63 and WACC of 6.68%:
In our case, if I were fine with the low discount rate (required return) of 6.68% (our WACC) and had medium-high confidence in our DCF valuation, I would be willing to purchase Intel for under $60. Currently, Intel's stock is hovering around $45 per share, so in this case it would still be a buy.
The most important thing here when applying a margin of safety is to avoid being too aggressive with your margin of safety, or else you will miss good buying opportunities. On the other hand, if your margin of safety is too small, you may end up purchasing an overpriced company. Ultimately, this is where your understanding of the business and your investment thesis plays a role, which should help you to come up with a fair margin of safety figure.
Note that you can also apply this margin of safety to your personal required rate of return and ignore this step altogether. However, I would only recommend doing this if you are using a relatively high personal required rate of return, such as 20% or more, or are more experienced with valuation.
After completing a DCF valuation, you should have a range of stock prices you would be willing to purchase the company for. Now, it all comes down to patience, and having the discipline to wait for the company's stock price to fall within your stock's buy-price range.
If the stock price never falls within your buy-price range, it may be due to errors in your valuation or too high of a margin of safety, but more often than not it's simply because the stock price is overvalued and not at an attractive price. Therefore, as a value investor, there's nothing wrong with completing a DCF valuation and waiting one or two years before finally being able to purchase the company at the right price.
Moreover, as you continue to update and fine-tune your DCF valuation with new financials, you'll gain a better understanding of the company and may be able to come up with a more accurate valuation. Ultimately, this will provide you with the confidence that you're going to at least make your required rate of return every year.
It's also important to note that your conservative figures, sensitivity analysis, and margin of safety should protect you to an extent from errors in your valuation and the number of assumptions made in a DCF valuation. Therefore, even if you purchase a company at an undervalued price and the company's stock price continues to under-perform, you should already have a good understanding of the company which should help you to avoid making any bad short-term, emotional, and/or irrational investment decisions.
In closing, if anything else, completing a DCF valuation will give you a flexible, market independent, cash-flow based, and self-sufficient approach to understanding a company and what it's worth, along with providing you with the confidence you may need as a long-term value investor. Ultimately, this may drive significant long-term investment growth and put you one step closer to achieving your financial goals.
