What happened that day?

November 12, 1987 — the S&P 500 rose 2.74% to 248.52. No single cause for the day could be pinned down
October's one-day crash was past, and November was drifting lower again
The crash itself lasted a day, but the weeks after it swung two and three percent at a time
The issue of those weeks was the federal deficit: whether a deal to cut it would come moved prices days at a time
It capped two straight gains, was the highest close since November 6, and the seventh largest one-day gain of the year
From August 25 to December 4 the episode ran -33.51%
The low came in early December; getting back to the pre-crash level took close to two years
