Three to four weeks out you’re looking at 90% winners. The average S&P gain over the next 4 weeks was over 4%. Even the instances over the last year were followed by positive numbers over the next 3 weeks or so. They were 7/15/08 (+5.75% over the next 15 trading days), 8/7/08 (+2.73%), 12/9/08 (+1.64%), and 2/25/09 (+3.85%). Meanwhile, if you bought the leading SOX instead of the SPX the average 4-week trade across the entire sample set rose from 4% to 8.2%.
Score one for the bulls. (Although I’m still seeing several bearish studies as well.)
