Global Bear Market Concerns Spread as Report Claims 42 Countries Are Down More Than 20%

A widely circulated market tally claims that at least 42 countries now have benchmark equity indices trading more than 20% below their previous highs, highlighting the scale of the reported global stock market downturn.
The figures include South Korea's KOSPI down 46.1%, China's Shanghai Composite down 40.4%, Japan's Nikkei 225 down 21.1%, Taiwan's TAIEX down 20.5% and Hong Kong's Hang Seng down 26.9%. The same list places Brazil's Ibovespa 20.8% below its peak and Vietnam's HNX index down 48%.
Several reported declines are substantially larger, including Greece at 60.4%, Iceland at 76.3% and Cyprus at 94.4%. These figures require particular caution because the underlying reference dates, index methodologies and price adjustments have not been established.
A decline of 20% or more from a recent high is commonly used to define a bear market. However, comparing indices across countries requires consistent measurement periods, currencies and index definitions.
The reported tally suggests widespread market weakness, but the claim that 42 countries are simultaneously in bear markets should not be treated as independently verified without checking current index levels against their respective peaks.
