Recently, the performance mines were released, and many stocks failed to meet expectations, resulting in a daily limit of 100 shares for two consecutive days.

"Flash crash" stocks frequently appear, and Founder Securities thinks it may be related to the following factors:

1, there are a large number of trusts in the tradable shares. The financial deleveraging started on 20 17 has reached 1: 1 for securities companies and fund subsidiaries. And the trust still has leverage exceeding 1:2. It is the general trend for trust institutions to clean up capital allocation and reduce leverage ratio. In this context, the source of trust funds is restrained when banks clean up outsourcing business.

2. Some stocks have relatively average performance and high valuations.

3. Some major shareholders of individual stocks have a large proportion of equity pledge.
