There are many situations where selling is unavoidable

1) Some funds have provisions in their terms that require the invested targets to maintain dividends. When a company stops paying dividends, they may be forced to sell. For example, the HSBC dividend suspension incident a few years ago.

2) When companies face international sanctions and certain people have to sell, such as China Mobile and CNOOC a few years ago.

3) Major shareholders who took out financing for certain reasons but couldn't top up their margin in time due to rapidly falling stock prices, leading to forced liquidation. For example, the BYD shareholder liquidation incident a few years ago.

4) Companies being removed from major indexes, causing index funds tracking those indexes to sell passively. The most significant impacts come from MSCI and FTSE indexes.

5) Companies conducting cross-border physical distributions, where some fund companies/individuals cannot hold stocks from other regions and must sell. Or similar situations. Palit is a ready example.

6) When stocks are included in the Stock Connect program, many funds may sell due to liquidity considerations, or similar situations.
