CSI 50 selects stocks from the entire Chinese securities market (including the SSE Main Board, SZSE Main Board, ChiNext, and SME Board) to reflect the market, while SSE 50 only selects stocks from the SSE Main Board to represent the market.

SSE 50 picks the top 50 companies with larger market capitalizations and higher liquidity from the CSI 300. Almost all of them are either "white-chip" stocks or blue-chip stocks, uniformly industry leaders. Moreover, SSE 50 has a stronger financial sector bias! The financial sector's weight accounts for as much as 55.33%, more than all other industries combined.

Precisely because their stock selection ranges differ, the overall market conditions reflected by CSI 50 and SSE 50 are also different.

SSE 50 selects 50 stocks from the Shanghai securities market with larger scales and good liquidity to form a sample group, reflecting the price trends of leading enterprises. Generally, these stocks are heavily held by national teams, social security funds, and public funds.

The "Nifty 50" refers to 50 stocks with stable long-term upward trends covering the entire market, while SSE 50 consists of the top 50 stocks ranked by weight in the SSE 50 Index of the Shanghai Stock Exchange.

For the "Nifty 50," we more commonly refer to it as the "Nifty 100." This is because, in addition to the Shanghai Stock Exchange, we also have the Shenzhen Stock Exchange. Some high-quality companies choose to list on the SME Board or ChiNext, many of which are also domestic industry leaders and are favored by institutional funds and most investors.

In essence, there is not much difference between them—they are all leading enterprises. The only distinction lies in the different markets they choose for listing. In daily trading, they serve as important references for judging market strength and participation willingness.
