What happened

Everybody knows 1929. Almost nobody knows 1937, which is strange, because in percentage terms it was one of the fastest collapses ever recorded. The economy had clawed back most of the ground lost since 1932. Then policy tightened, spending was cut, and the market fell 52% from the start of this window.

The couch ends with $7,682. On October 18, 1937 it lost 9.1% in a day. In October 1938 it gained 8.3% in a day. Same market, thirteen months apart, and you had to be on the right side of both.

This window closes in March 1939, six months before the war starts. The recovery it hands you is real but unfinished.

The read

57.0% of 1,600 players beat the couch, and 16.1% of them never traded at all. The 1937 hand is the archive's cleanest test of nerve: the fall is fast enough to escape if you move early, and the bounce is fast enough to miss if you stay out. Most players did one of the two, not both.
