The state didn't say to restrict quantitative hedge funds, but after the stock market crash last year, the state restricted the number of open positions of stock index futures, which increased the intraday trading cost, so the stock index futures strategy was not good. In addition, after the stock market crash last year, stock index futures have been discounted. In the past, more than 80% of domestic quantitative hedging strategies were alpha strategies. This strategy is to hedge stock index futures by purchasing a basket of stocks by quantitative means. The basic logic is that a basket of stocks outperforms the broader market when it rises, and falls less than the broader market when it falls, so that it can make money regardless of market ups and downs. But now, because the premium of stock index futures exceeds 10% a year, it is equivalent to the cost of hedging 10% a year. Figuratively speaking, the stock you buy will outperform the broader market by 65,438+00% a year before you lose money. So this strategy is basically a rest this year. According to my friends in a circle, Rongqi investment is mainly a combination strategy. Through statistical arbitrage, options and CTA strategies, the maximum number of products withdrawn in the first half of this year is only 1600, which is very rare. You can buy a fund network or a private equity network to see the performance of their products. They released 15 products, and the management scale should be above10 billion.
