This post-WWII bear market was caused by investors mistakenly assuming that the end of wartime spending would result in an economic slowdown. Instead, there was a period of massive inflation and pent-up demand as those returning from the war tried to regain their footing.
The pent-up demand after World War 2 led to an increase in inflation and speculation. As a result, in January 1946, regulators increased margin requirements for stock purchases from 75% to 100%. To meet these new requirements, many investors had to sell their shares, which contributed to the market going into a tailspin.
