If the net value of the unit is very high, it means that the fund's growth rate is good at a certain stage, which means that the fund's underlying stocks have risen for a period of time, and the stock market is volatile. When the stock price rises for a long time, the margin of safety decreases.

Be aware of the risks.

If the cumulative net value is too high, it means that the fund has good historical performance since its establishment, with good dividends and high investment capabilities, and the fund manager has strong investment capabilities. At this time, if the net value of the unit is low, you can consider buying it.

On the other hand, if the cumulative net value of the old fund is not high, it means that the fund pays out dividends less often and the return on investment is not high.
