A Repeat Of 'Black Monday' Would Send The S&P 500 Down More Than 1,500 Points And Wipe Out More Than $13 Trillion In Stock Market Value

A repeat of 'Black Monday' would send the S&P 500 down more than 1,500 points and erase over $13 trillion in market value, the headline estimate from 24/7 Wall St. The estimate surfaces on the anniversary of that 1987 plunge, a date highlighted by Seeking Alpha as the day Nasdaq and S&P futures bounced back. Benzinga frames the moment as a question of whether the S&P 500 will open up or down, while RealMoney Pro revisits the “very dark day” of the original crash.

A Wausau Pilot & Review note marks the calendar as Sunday, Oct. 19, the 292nd day of 2025, underscoring the temporal link to past market turbulence. The bounce in futures suggests short‑term optimism among traders, yet the stark headline from 24/7 Wall St. tempers expectations. Investors, pension funds, index managers and corporate balance sheets would feel the hit if the projected dip materialises.

Market watchers will monitor opening prices, futures trajectories and any Federal Reserve or Treasury commentary for directional cues. Analysts are expected to compare the movement against historical volatility benchmarks and may adjust risk models accordingly. The next trading session will reveal whether the futures bounce translates into broader equity recovery or deepens the decline.
