Step 2: Substitute data for calculation.\end{align*}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\%.
Substituting r = 0.01 and n = 240 into the above formula, we can get:Substituting r = 0.01 and n = 240 into the above formula, we can get:This means that after 240 trading days, the overall increase multiple is about 10.8926 times, and the increase is (10.8926-1) \times 100\% = 989.26\%.
\end{align*}If it rises by 1% or 2% every day, how much will it increase in 240 trading days a year?Therefore, according to the daily increase of 1\%, the increase is about 989.26\% after 240 trading days.
