Step 1: Review the formula of compound interest final value.1.01 {240} \ approximate 10.8926 is calculated by a calculator.\begin{align*}
If it rises by 1% or 2% every day, how much will it increase in 240 trading days a year?Therefore, the daily increase is 2%, and after 240 trading days, the increase is about 11,488.87 \%.F&=(1 + 0.01)^{240}\\
If it rises by 1% or 2% every day, how much will it increase in 240 trading days a year?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:Therefore, the daily increase is 2%, and after 240 trading days, the increase is about 11,488.87 \%.
