Explanation
A lifecycle fund is a type of asset-allocation fund that automatically adjusts its portfolio composition according to the investor's age and risk tolerance. As the investor gets closer to their retirement date or target date, the fund shifts from more risky assets, such as stocks, to less risky assets, such as bonds and cash. This is done to reduce the volatility and preserve the capital of the fund as the investor approaches their withdrawal phase. Therefore, statement A is true about lifecycle funds. Statement B is false because different lifecycle funds may have different initial allocations depending on their target dates and risk profiles. Statement C is false because the asset allocation of a lifecycle fund changes over time according to a predetermined glide path that gradually reduces risk. Statement D is false because investor income is not the only basis for changing the asset allocation of a lifecycle fund; other factors, such as age, risk tolerance, investment objectives, and time horizon, are also considered.
