Assuming under the same trading strategy, the annual return rate for long-term investments is 12%, with an average monthly return rate of 1%. For short-term investments, the monthly return rate is also 1%, but it is continuous for 12 months. As a result, the actual annual return rate for short-term investments is not 12% anymore, but 1.01^12 = 1.1268, which is a return rate of 12.68%.
