VHSI – the Volatility Benchmark for Hong Kong’s Stock Market

The HSI Volatility Index (VHSI) is an indicator of Hang Seng Index (HSI) volatility, and thus of the Hong Kong stock market. The VHSI is also seen as Hong Kong's premier barometer of investor sentiment.

VHSI Overview

The VHSI is a key measure of the market’s expectation of 30-day HSI volatility implicit in the prices of near-term and next-term HSI options traded on HKEx’s derivatives market. VHSI is an implied, or expected, volatility index and is quoted in percentage points. 

The VHSI is owned by Hang Seng Indexes Ltd and compiled according to the CBOE’s Volatility Index, or VIX, methodology, with adaptation to the Hong Kong stock market’s characteristics. The VHSI was launched on 21 February 2011.

Benefits of VHSI as a Volatility Benchmark

Volatility indexes enhance the pricing efficiency of options markets because investors can use them to compare derivatives pricing and estimate the implied volatility in options pricing.

Relationship between VHSI and HSI

A volatility index is commonly viewed as a useful gauge for changes in investor sentiment. Some professional investors treat volatility as an alternative asset class for investing.
