Step 2: Substitute data for calculation.Substituting r = 0.01 and n = 240 into the above formula, we can get:\begin{align*}
\end{align*}This means that after 240 trading days, the overall increase multiple is about 10.8926 times, and the increase is (10.8926-1) \times 100\% = 989.26\%.\end{align*}
The following is to calculate the increase of 240 trading days according to the daily increase of 2%, and calculate it through the calculator, 1.02 {240} \ approximate 115.8887.1.01 {240} \ approximate 10.8926 is calculated by a calculator.If it rises by 1% or 2% every day, how much will it increase in 240 trading days a year?
