Step 1: Review the formula of compound interest final value.\begin{align*}
Step 1: Review the formula of compound interest final value.This means that after 240 trading days, the overall increase multiple is about 115.8887 times, which is converted into the form of increase percentage, and the increase is (115.8887-1)×100\% = 11488.87\%.\begin{align*}
Step 2: Substitute data for calculation.Therefore, the daily increase is 2%, and after 240 trading days, the increase is about 11,488.87 \%.F&=(1 + 0.01)^{240}\\
