Introduction to the SSE Composite Index

The SSE Composite Index, also known as the Shanghai Composite Index, is the definitive performance indicator of all stocks traded on the Shanghai Stock Exchange (SSE). Launched in 1991, it covers both A-shares (priced in CNY) and B-shares (priced in USD), making it the most inclusive index in mainland China’s financial market. As one of Asia’s largest and most watched indices, its movement signals investor confidence, economic momentum, and policy impact across China’s vast economic landscape.

Evolution and Significance of the SSE Composite

Since its inception with a base value of 100, the SSE Composite has evolved into a key reflection of China’s economic and corporate development. The index is heavily influenced by state-owned enterprises (SOEs), large banks, industrial giants, and emerging tech firms, representing a unique mix of stability and innovation.

Key Milestones:

• 1991: SSE Composite officially launched.
• 2007: Index reaches an all-time high above 6,000 points, driven by economic boom and speculative trading.
• 2015: Notorious stock market crash follows a rapid surge, prompting sweeping regulatory reforms.
• 2020-2023: COVID-19 recovery, tech crackdowns, and global macroeconomic shifts influence index volatility.

Methodology: How the SSE Composite Index Is Calculated

The index is capitalization-weighted, meaning larger companies have a greater effect on the index. Unlike price-weighted indices, the SSE Composite considers total market value by multiplying share price with tradable shares.

Formula:

plaintextCopyEditSSE Index = (Σ(Pi × Qi) / Σ(Pi0 × Qi)) × 100

Where:

• Pi = Current price of stock i
• Qi = Number of tradable shares
• Pi0 = Base price of stock i

This formula ensures that changes in the value of large companies affect the index more than small-cap fluctuations.
