The DJIA index fell 22.6% on Monday 19 October 1987, plunging 508 points to 1738. In the wake of Trump’s tariff war announced on 2/4/25, a similar percentage fall on Monday 7/4/25 would have taken 8,000 points off the DJIA. As it turned out, Monday was relatively calm following Thursday’s 5% drop and Friday’s 6% drop.
