The Dow Jones Industrial Average ended the day with a gain of 420 points, the biggest one-day point gain in more than five years.
But there's more reason for the bulls to cheer than the magnitude of the day's point gain. Tuesday's action also was strong enough to trigger a bullish technical event known as a "Double Nine-To-One" signal.
This indicator is based on 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. On a day when rising stocks' volume is the same as declining stocks' volume, for example, this ratio would be exactly 50%.
A single "Nine-To-One Up Day" occurs when this ratio is 90% or higher on a given day. According to Martin Zweig, who helped to develop this indicator several decades ago, such a huge imbalance of up volume over down volume "is a significant sign of positive momentum. In other words, when daily up volume leads down volume by a ratio of 9-to-1 or more, that tends to be an important signal for stocks." The quotation comes from Zweig's 1986 book, "Winning on Wall Street."
