\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\%.Step 1: Review the formula of compound interest final value.
If it rises by 1% or 2% every day, how much will it increase in 240 trading days a year?F&=(1 + 0.01)^{240}\\F&=(1 + 0.01)^{240}\\
&=1.01^{240}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.\begin{align*}
