Best Performance Since 1939

CNBC is reporting that the market's performance this month is the best since September 1939. There was no mention of the fact that the Dow fell 30% from September 13, 1939 to June 19, 1940 with most of the decline coming in May 1940 in a deep zigzag correction. In 1939, the Dow fell modestly after September with two multiweek rallies. I'm not suggesting that the same thing must happen this year, but the parallels are interesting.
