The phenomenon of homogenization is serious. For those products with some characteristics, funds have always been flocking to them. 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 certain fund company told the reporter of the "Ninth Economic Daily" thus: "In fact, we found that the silver China fund index分级product share growth was very fast. Silver China's 100 on-exchange shares have exceeded 6 billion shares, and the on-exchange shares of Silver China’s CS Index Equal Weight 90 reached a scale of 4 billion yuan. The originally on-exchange shares tracking the resource index were only more than 40 million, but now it also reaches 500 million. The on-exchange shares of active type分级products have not changed much." Under the situation where new fund issuance mainly relies on "buying one lottery ticket,"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, the CS500 Index and the CSI300 Index are the most common. The分级fund selection target of Huashang and Jinguo Fund is the CS500 Index, while the first分级fund of Huaan and Jiaoyin both tend towards the CSI300. Shenzhen 100, SME board, Shenzhen 300, and bulk commodities etc., indexes are also choices for multiple fund companies to layout分级funds. "There are only so many major market indexes, the company originally wanted to choose the CS500 Index, but seeing that there are quite a number of this type of分级ones, it then switched to one with slightly less elasticity," a market person from a Shenzhen fund company frankly admitted. "Now all分级funds are about the same. The management's issuance of分级fund product review guidance imposes certain restrictions on the leverage ratio of various types of products," the market person further stated.
