## Multi-Stage DDM Calculator for Stock’s Fair Value (Continued)

Constant Rate Multi-period DDM: This method is essential when you plan to purchase a stock this year and intend to sell it two or more years later. It accounts for scenarios where dividend payments from the stock vary throughout this multi-period duration.

## How to Calculate the Discount Rate or Cost of Equity

The discount rate, often referred to as the cost of equity, plays a pivotal role in fair value calculations. It's not a one-size-fits-all figure; rather, it's a customized rate based on several factors:

Risk-Free Rate: This represents the interest or return an investor should expect from zero-risk investments. Government bonds, such as the long-term (e.g., 10-year) treasury bonds, are often used as a benchmark for the risk-free rate.

Beta: Beta measures the volatility of the stock in relation to the overall market. You can find beta values for individual stocks on financial websites. A higher beta indicates greater volatility and risk.

Market’s Annual Return: This is the average annualized historical return of the stock market, often calculated over the long term (20-30 years). In the United States, for instance, the historical average annual return for the S&P 500 hovers around 10%.

The discount rate formula is as follows:

Discount Rate = Risk-Free Rate + Beta * (Market’s Annual Return - Risk-Free Rate)

Choosing the appropriate discount rate is crucial because it reflects the risk associated with the specific investment. Riskier investments typically demand a higher discount rate to account for the increased potential for loss of investment capital.

## Discounted Cash-flow (DCF) Calculator

The Discounted Cash-flow Model adopts a quantitative approach, calculating a company’s stock price based on the sum of all future free cash flows earned from that company, discounted at a rate that accounts for both time and risk. The key principle here is recognizing that money today is more valuable than money in the future, due to its earning potential.

Consider a scenario where you lend a friend \$100, and they return the same amount after 5 years. The \$100 you receive after 5 years isn't worth the same as it is today, because your initial \$100 could have been earning interest during that time. This concept underpins the need to discount future earnings to determine their fair value in today's terms.

## Peter Lynch’s Fair Value Formula

Legendary investor Peter Lynch introduces a simplified approach to fair value using the PEGY ratio. In this method, the PEGY ratio is inverted to assess the stock's valuation. The PEGY ratio compares a company's growth rate (including dividend yield) to its Price-to-Earnings (P/E) ratio.

Lynch's Fair Value Formula is as follows:

Peter Lynch’s Fair Value = (Earnings Growth Rate + Dividend Yield) / P/E

• Earnings Growth Rate: Use the estimated future long-term growth rate, which can be an average of the next 3-5 years' Earnings-per-Share (EPS) growth rate. Alternatively, you can utilize the average earnings growth rate from the past 5-10 years if future estimates are unavailable.
• Dividend Yield: Calculate the latest dividend yield by dividing the latest annual cash dividend per share by the share price.
• P/E (Price-to-Earnings) Ratio: This is obtained by dividing the stock price by the EPS.

The resulting value from Lynch's formula indicates the stock's relative valuation. A ratio of 1 suggests fair valuation, while values below 1 indicate overvaluation, and values above 3 signal significant undervaluation.

#### Examples:

Here are some examples of stock fair value calculations using Peter Lynch's method:

Peter Lynch's Ratio Formula: Lynch’s Ratio = (EPS Growth + Dividend Yield) / (Trailing P/E)

#### High Growth Company Valuations:

Facebook: Lynch’s Ratio = (28.6 + 0) / 28.01 = 1.02 (Fairly-Valued).

Google: Lynch’s Ratio = (24.41 + 0) / 31.4 = 0.78 (Over-Valued).

Microsoft: Lynch’s Ratio = (15.25 + 0.75) / 37.11 = 0.43 (Very Over-Valued).

Amazon: Lynch’s Ratio = (35.77 + 0) / 61.15 = 0.58 (Over-Valued).

#### Low Growth Company Valuations:

Johnson & Johnson (JnJ): Lynch’s Ratio = (8.89 + 2.46) / 25.83 = 0.44 (Very Over-Valued).

Altria: Lynch’s Ratio = (4.67 + 7.09) / 20.67 = 0.57 (Over-Valued).

AT&T: Lynch’s Ratio = (2.7 + 7.55) / 8.51 = 1.2 (Fairly-Valued).

Merck & Company: Lynch’s Ratio = (12.77 + 3.42) / 13.17 = 1.23 (Fairly-Valued).

Peter Lynch's fair value calculation offers a quick and straightforward method for stock valuation, making it accessible to beginners. It provides a powerful way to assess stock values. However, it's essential to recognize its limitations, including its inability to calculate an exact intrinsic value and its focus on specific metrics without considering broader business fundamentals. Additionally, it may tend to undervalue slower-growing companies.

## Benjamin Graham’s Number Calculator for Stock’s Fair Value

Benjamin Graham's Number serves as a safeguard against overpaying for a stock. It's derived using the following formula:

Graham Number = √(15 * 1.5 * EPS * BVPS)

• 15: This parameter represents the maximum value of the Price-to-Earnings (P/E) ratio that an investor should pay for a stock.
• 1.5: This parameter represents the maximum multiple of the Price-to-Book (P/B) ratio an investor should pay for a stock.
• EPS (Earnings Per Share): Divide the net earnings by the total number of outstanding shares to calculate EPS.
• BVPS (Book Value Per Share): Subtract total liabilities from total assets to determine the company’s Book Value (BV). Then, divide BV by the total number of shares outstanding to find BVPS.

Customizing the parameters of Benjamin Graham’s Number can be done in two ways:

1. Use Sector/Industry Median: Different industries have distinct dynamics. Customize the parameters based on sector or industry averages to ensure your valuation aligns with industry-specific benchmarks.
2. Use Stock’s Long-term Mean: Leverage the tendency of values to revert to their mean over time. Calculate the stock's long-term (e.g., 10-15 years) mean of P/E and P/B and use those values instead of the standard P/E = 15 and P/B = 1.5. This approach tailors the valuation to the specific stock's historical performance.

#### Examples:

Here are examples of stock fair value calculations using Benjamin Graham's Number:

Graham’s Number Formula: Graham Number = √(Sector P/E * Sector P/B * EPS * BVPS)

Customizing Graham's Number with Sector Median P/E and P/B:

To tailor the Graham Number to industry-specific benchmarks, we use sector median P/E and P/B ratios as the maximum values for P/E and P/B in the formula.

Valuation Examples:

• Facebook: Graham Number = √(21.88 * 2.6 * 13.58 * 49.03) = \$194.6 USD.
• Google: Graham Number = √(21.88 * 2.6 * 92.15 * 683) = \$1,892.2 USD.
• AT&T: Graham Number = √(21.88 * 2.6 * (-0.31) * 22.73) = Not Applicable (NA).
• Alibaba: Graham Number = √(15.64 * 3.01 * 8.33 * 55.6) = \$147.6 USD.
• Johnson & Johnson (JnJ): Graham Number = √(36.01 * 3.79 * 6.65 * 26.43) = \$154.9 USD.
• Bank of America: Graham Number = √(10.75 * 1.17 * 3 * 30.15) = \$33.7 USD.

Benjamin Graham's Number is a potent method for determining the maximum price of a stock, particularly suitable for beginners due to its simplicity. However, it does have its limitations:

• Uniform Parameters: It assumes the same parameter values for every industry.
• Negative Earnings Per Share: It cannot calculate intrinsic value when Earnings Per Share (EPS) is negative.
• Underestimating High-Growth Stocks: It has a tendency to underestimate the valuation of high-growth stocks.

Despite these limitations, Benjamin Graham's Number remains a valuable tool for investors, offering a straightforward approach to stock valuation.
