Step 1: Review the formula of compound interest final value.Substituting r = 0.01 and n = 240 into the above formula, we can get:
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}\\Step 2: Substitute data for calculation.
\begin{align*}Step 2: Substitute data for calculation.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\%.
