Shanghai Composite Index (SSEC) — Comprehensive Guide

What Is the Shanghai Composite Index (SSEC)?

• The Shanghai Composite Index, also known by its ticker .SSEC or 000001.SS, is a broad‐market index which tracks all A-shares and B-shares listed on the Shanghai Stock Exchange (SSE).
• It is often used as a barometer for the health of the Chinese mainland stock market, especially for China’s domestic economy.

Key definitions:

• A-shares: Stocks in Shanghai (or Shenzhen) denominated in Chinese yuan (CNY), without foreign restrictions (though some foreign access through QFII, Stock Connect, etc.).
• B-shares: Stocks denominated in foreign currencies or tradable by foreigners under specific regulations. Over time, their relative importance has diminished in many investors’ view.

History & Base Calculation

Item	Details
Inception / Base Date	The SSE Composite was established in 1991. Its base value is set according to a base period (around December 1990) with base value 100.
Index Type	It is a composite price index, meaning it measures price movements of its component securities, not adjusted for dividends. It includes both A and B share classes.
Weighting	The SSE Composite is market-cap weighted, but because it includes a huge number of firms (many small, many large; many state-owned), weighting skew often occurs toward large financials and state-owned enterprises.

Constituents & Composition

• The index includes all companies listed on the Shanghai Stock Exchange (both A & B shares). As of recent data, that means well over 1,400-1,500 listings.
• Sector breakdown tends to have heavy weighting toward Financials, Industrials, Materials, with others like Consumer Staples, Technology growing but less dominant.
• Because many state-owned or state-influenced firms are in the index, sectors intertwined with government policy (banks, utilities, infrastructure) often carry outsized influence.
