• D. A strategy for short-term trading

Answer: (A)

Compounding in investing refers to the process where investment earnings, such as interest or dividends, generate additional earnings over time. This concept is fundamental to building wealth because it allows money to grow at an accelerating rate. For example, when you earn interest on your investment, that interest becomes part of your principal. In the following period, you earn interest not only on your original investment but also on the interest that has already been added. As this cycle continues, the value of the investment increases more rapidly compared to simple interest calculations, where earnings do not earn further interest.

The power of compounding is particularly potent over long periods, making it a critical strategy for long-term investors. This principle illustrates why starting to invest early can lead to significantly greater returns compared to investing a larger sum later on, emphasizing the importance of time in the investment process.
