I've discussed many times in the past that Tuesdays have a well-earned reputation for being a day when the market will often halt a decline. The study below is one from the larger Turnaround Tuesday study. It was last published in the 1/31/12 blog. All statistics are updated.
As you can see the market has strongly favored a quick move higher. And when that move hasn’t happened on Tuesday it has often happened in the next few days.
