1, it is hard to say whether it is good or bad, but it must be stable. The fund will do detailed research before buying stocks, such as fundamentals and development prospects.

2. In the process of adjustment, the fund's heavy position will show good resilience: but as far as I can see, it is ironic that the increase of the fund's heavy position in the bull market is relatively small, after all, the risk will be smaller and the income will be smaller.

It depends on several situations:

1 is whether the size of individual stocks is small. Usually, small-cap stocks are relatively easy to rise after the fund invests heavily;

2. Number of funds with heavy positions. If more than one fund enters, it will still rise with the broader market when it is smooth, but once it weakens, it will fall faster than the broader market.

3 is the style of the fund, and most of them follow suit. If you encounter such a heavy fund position, it is not a good market to enter the market with retail investors.
