double 9-to-1 signals The particular technical signal is referred to as a "Nine To One Up Day." It refers to the volume of all NYSE-listed stocks that go up on a given day, expressed as a percentage of the total volume of all stocks that rose or fell on that day. In this case 9 out of ten stocks are up, and double means twice in a close time interval. Based on a book entitled "Evidence-Based Technical Analysis" (Wiley, 2007) written by Professor Aronson, S&P 500 gained an average of 22% within 60-trading-day after a double 9-to-1 signal was triggered since 1942.
The last double 9-to-1 signal was: March 14 and 21 (within a week)
