Shanghai SSE Composite Index — Level, Chart & Constituents

What the Shanghai SSE Composite measures

The Shanghai SSE Composite is a market-capitalization-weighted index that tracks the performance of all A-shares and B-shares listed on the Shanghai Stock Exchange. It serves as a broad barometer of the Chinese mainland equity market and is part of the Asia-Pacific region alongside peers such as the Nikkei 225, the Hang Seng Index, and the BSE Sensex. Because it includes both A-shares (denominated in CNY and traded on the mainland) and B-shares (denominated in foreign currencies), the index reflects a mix of domestic and foreign-invested capital flows.

Key numbers explained

• The current index level of 3,936.52 points represents the aggregate market value of all constituent stocks relative to a base period; a higher level means the total market value has risen since the base date.
• Today's low and high of 3,934.46 and 3,951.52 show the intraday trading range, indicating how far the price moved from its lowest to its highest point during the session.
• The price change today of -0.34% tells you the index closed slightly below its previous close, a modest single-day move.
• The 52-week low of 3,741.11 and 52-week high of 4,258.86 mark the lowest and highest levels reached over the past year, framing the current level within its annual range.
• The index currency is CNY, meaning the level is quoted in Chinese yuan; for international investors, currency movements can affect the return when converted to another currency.

What to watch

Investors tracking the Shanghai SSE Composite often monitor macroeconomic data from China, such as manufacturing activity and trade figures, because they can influence corporate earnings and market sentiment. Policy decisions by the People's Bank of China and the China Securities Regulatory Commission, including changes to margin requirements or trading rules, can also affect liquidity and volatility. Global risk appetite, commodity prices, and geopolitical developments are additional factors that historically move the index, alongside flows into and out of the broader Asia-Pacific region.
