Check the fund positions and heavy positions only through the quarterly report issued by the fund company.

Quarterly reports are generally released about 20 days after the end of the quarter.

Only the top 10 stocks of the fund are published in the quarterly report.

The position shown in the quarterly report only represents the position of the fund at the end of the quarter.

And it was released after 20 days, so the situation will change more or less after 20 days.

It's just a rough idea, and it can't be accurate.
