Net value increase is the degree of change in the net value of a fund or other investment product within a certain period of time.

If the net value increase of a fund is 0, it means that the fund has not received positive or negative returns during this period.

If a fund's net value increase is zero, it usually means that the fund's performance during this period is in line with the market average, that is, it neither outperforms nor underperforms.

At this time, the fund can be considered to have a stable nature, or that the securities or other assets it invests in have equal gains and losses.

Of course, when choosing a fund, investors not only pursue stability, but also need to comprehensively consider factors such as its historical performance and fund management capabilities.

For investors holding funds with zero net value increase, the best approach is to calmly analyze market trends, evaluate the securities or assets held by the fund, and determine whether they need to withdraw.

If investors hold the fund for a long time, they can consider maintaining it in anticipation of better development in the future.

However, if a fund with zero gains has exceeded the long-term holding threshold, investors can consider switching to other funds or assets with better performance.
