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}\\
\end{align*}&=1.01^{240}Therefore, according to the daily increase of 1\%, the increase is about 989.26\% after 240 trading days.
\end{align*}Therefore, according to the daily increase of 1\%, the increase is about 989.26\% after 240 trading days.Therefore, the daily increase is 2%, and after 240 trading days, the increase is about 11,488.87 \%.
