If a fund falls by 50%, it may rise back. If the fund wants to rise back to its original price, it needs as much money as it loses. For example, if the fund loses 50%, it needs to rise by 100% to recover its capital. It should be noted that the recovery of funds is not achieved overnight, and it may take some time, and some funds may take 2 or 3 years to recover. In addition, if the market is bad or the fundamentals of the fund are poor, investors may need to wait longer, and if the fund continues to fall, investors may face greater losses. Therefore, investors need to comprehensively consider the market situation, fund fundamentals and personal risk tolerance when deciding whether to increase their positions or continue to hold them.
