How do you calculate the compound annual growth rate (CAGR) for a stock?

@augustine

To calculate the compound annual growth rate (CAGR) for a stock, you follow these steps:

- Determine the starting value (initial price) of the stock and the ending value (final price) over a given period. The ending value should be for a date later than the starting value.
- Divide the final price by the initial price to get the total return. Total Return = (Final Price / Initial Price)
- Take the nth root of the total return, where n is the number of years or periods. For example, if you are calculating CAGR for a 5-year period, n would be 5. CAGR = (Total Return)^(1/n)
- Subtract 1 from the above result to get the CAGR. CAGR = [(Total Return)^(1/n)] - 1

Note: The CAGR represents the average annual growth rate over the given period, assuming the growth rate is constant. It provides a smoothed out view of the stock's growth.

It is important to note that CAGR does not take into account any fluctuations or volatility in the stock's price over the period being analyzed. It assumes a constant growth rate, which may not always be the case in reality.

Here is an example to illustrate how to calculate CAGR:

Let's say you want to calculate the CAGR for a stock over a 5-year period. The initial price of the stock was $100 and the final price after 5 years is $150.

Step 1: Determine the total return: Total Return = Final Price / Initial Price = $150 / $100 = 1.5

Step 2: Calculate the CAGR: CAGR = (Total Return)^(1/n) = 1.5^(1/5) ≈ 1.095

Step 3: Subtract 1 to get the CAGR: CAGR = 1.095 - 1 ≈ 0.095 or 9.5%

Therefore, the CAGR for this stock over the 5-year period is approximately 9.5%.

Remember that CAGR is just one metric to consider when evaluating a stock's performance, and it is important to analyze other factors such as the company's fundamentals, market conditions, and risk tolerance before making investment decisions.
