According to the announcement of Everbright Securities, they originally wanted to buy millions of shares, but the system went wrong and bought billions. Such a large turnover drove the stock market to rise, and everyone was more excited and began to buy. But the boss of Everbright will definitely not want it, because the funds of big companies are planned, but they can't be sold until the next day. What should I do? There is a kind of fund called ETF, which simply means trading stocks for fund products. So many stocks bought by Everbright can be directly converted into ETFs, and then the ETFs can be sold to get the money back. At the same time, Everbright also sold thousands of stock index futures, that is, when the market index fell, it could get interest compensation. The operating market like Everbright began to fall, and the people who chased it up were miserable. Because everbright announced that it had made a mistake after all these things happened, which constituted insider trading (that is, using information that others did not know to make profits in the transaction, for example, everyone did not know the real reason for the sudden rise of the market at first. )。 Everyone must be reluctant. The CSRC has also begun to investigate this matter.

That's probably it. Some nouns are complicated, so I won't go into too much detail.
