Because the sample of Shanghai Stock Exchange Index is too large (covering all stocks of Shanghai Stock Exchange, including B shares), it is extremely difficult to track, so there are few ETFs that track the Shanghai Stock Exchange Index. At present, the only ETF on the market is Guo Fu SSE Index ETF(5 102 10). Huitianfu also has an index fund that tracks the SSE Index, but it cannot be called ETF because it is not listed. Rich countries' Shanghai Stock Exchange ETF will not buy all the stocks, but only partially copy them by sampling technology to minimize the tracking error with the index. As can be seen from the attached figure, since July 65438+2003, the trend of ETF and Shanghai Composite Index is basically the same.
