There is no direct superposition relationship between the two. Hedge fund is an investment strategy, the purpose of which is to gain income through long and short transactions, while rolling interest is a way to increase investment income, and realize capital appreciation through compound interest effect.
In the actual investment, hedge funds adopt the strategy of rolling interest and reinvest the proceeds to obtain higher returns. This can further increase the compound interest effect of funds, but this does not mean that the concepts of hedge funds and rolling interest are directly superimposed.
