The second bottom is when the market falls to the original low again after the previous low. However, if the market continues to be optimistic, investors will buy at the low and the price may rebound. Or enter a state of shock, and a support will be formed at this lowest level.

Generally, if there is a second bottom in the market, it is a good signal, and fund investors can regard it as a good buying opportunity. But we still need to pay attention to whether the support level continues to be effective and whether the market will fall again.
