The Hang Seng is a stock market index for the Hong Kong stock exchange.

Hong Kong, as a global financial hub, plays a pivotal role in the Asian and international financial markets.

The Hang Seng Index (HSI) is the region’s primary stock index and a benchmark for Hong Kong’s leading companies.

What is the Hang Seng Index?

The Hang Seng Index, launched in 1969 by Hang Seng Bank, is a market capitalization-weighted stock index that tracks the performance of the 50 largest and most liquid companies listed on the Hong Kong Stock Exchange.

The index is named after the company’s founder, Ho Sin Hang.

The index provides a comprehensive representation of Hong Kong’s major industries, including financials, property, utilities, and commerce and industry, making it a crucial benchmark for tracking the performance of the Hong Kong stock market.

How is the Hang Seng Index calculated?

The Hang Seng Index is calculated using a market capitalization-weighted methodology, which assigns a higher weight to companies with larger market capitalizations.

Additionally, the index takes into account the free float, or the proportion of shares readily available for trading, of each company.

This ensures that the index’s performance is driven primarily by the largest and most influential companies in the Hong Kong market.

The HSI is reviewed and rebalanced quarterly to ensure it remains up-to-date and accurately represents the performance of Hong Kong’s top companies.

During the review process, any necessary adjustments are made to the index constituents, including the addition or removal of companies based on their market capitalization, liquidity, and other eligibility criteria.

Why is the Hang Seng Index important?

  • Benchmark for Performance: The Hang Seng Index serves as a benchmark for investors to gauge the performance of Hong Kong’s leading companies and compare it with their own investment portfolios or other investment opportunities.
  • Exposure to Hong Kong’s Market: The index provides exposure to Hong Kong’s domestic stock market, offering investors a way to participate in the growth of the region’s economy and benefit from the performance of its top companies.
  • Diversification: The Hang Seng Index offers a diversified investment opportunity, with exposure to a range of industries, helping to reduce sector-specific risks and enhance the index’s overall stability.
  • Indicator of Hong Kong’s Economic Health: As the index represents the performance of Hong Kong’s largest and most influential companies, its movements often serve as an indicator of the region’s overall economic health and investor sentiment.
