\begin{align*}Therefore, the daily increase is 2%, and after 240 trading days, the increase is about 11,488.87 \%.\end{align*}
Therefore, the daily increase is 2%, and after 240 trading days, the increase is about 11,488.87 \%.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*}
We can use the formula for calculating the final value of compound interest to calculate the final increase under this continuous growth situation. The following are the specific steps: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}\\
