This formula gives the percentage increase in the stock price over a certain period of time. For example, if a stock's price was $50 at the beginning of the year and $60 at the end of the year, the stock growth would be calculated as: ($60 - $50) / $50 = 0.20 or 20%. This means the stock grew by 20% over the year. **
