The phenomenon of homogenization is serious. For those products with some characteristics, funds have always been in a rush. The arbitrage opportunity presented by high-leverage funds has become the best way to expand the parent fund. In this round of surveys, a person in charge of the product department of a fund company told the reporter of "Ningbo Evening News" like this: "In fact, we found that the share growth of YinHua Fund Index分级products is very fast. The on-exchange shares of YinHua Shen100 have exceeded 6 billion shares, and the on-exchange shares of YinHua Zhongzheng equal-weighted 90 have reached a scale of 4 billion yuan, the originally on-exchange shares of the resource index only had more than 40 million shares, and currently there are also 500 million. The on-exchange shares of active分级products have not changed much." Under the situation where new fund issuance mainly relies on "buy one get one free money",分级funds also attract more fund companies to embark on the road of分级funds. Among the 15分级funds that have passed the CSRC meeting, the proportion of index-type分级stock products exceeds ninety percent. In terms of the selected tracking targets, they are mostly based on the CSI 500 Index and the SSE & SZSE 300 Index. For example, the分级funds of Huashang and JinEagle choose the CSI 500 Index as their target, while the first分级fund of HuaAn and Jiaoyin both tend to be inclined towards the SSE & SZSE 300. Shenzhen 100, SME board, Shenzhen 300, and bulk commodities and other indices are also the choices for multiple fund companies to deploy分级funds. "There are only so many major market indices, the company originally wanted to choose the CSI 500 Index, but after looking at the relatively large number of分级of this type, it changed to a slightly smaller elasticity." A market person from a Shenzhen fund company admitted. "Now all分级funds are about the same, the management's issued分级fund product review guidelines impose certain restrictions on the leverage ratio of various types of products." This market person also said.
