Which Hong Kong stock index fell about 45.8% during the week of the 1987 global crash?

The Hang Seng Index fell about 45.8% during the week of the 1987 global stock-market crash.

Hong Kong’s market was among the first major markets to suffer a dramatic decline in the international sell-off. Trading was suspended for several days after the collapse, and the market reopened amid intense investor fear.

The Hong Kong fall demonstrated that the crash was not confined to the United States. Markets in Australia, the United Kingdom, Japan, and elsewhere also recorded severe losses, although their exact dates and percentages differed.

The Hang Seng Index is often confused with Japan’s Nikkei 225 because both are prominent Asian benchmarks. The Hang Seng tracks major companies listed in Hong Kong, while the Nikkei 225 tracks 225 leading companies listed in Japan.
