Dips and Crashes: stocks that fell sharply

The Dips & Crashes scanner lists U.S. and Canadian stocks whose close fell at least 25% over the last 14, 30, 90, 180 or 365 days. When a single session dropped 15% or more along the way, it flags that day as a crash, with its date, size and volume.

Some of these stocks are cheap for a reason, and some bounce. Seeing how far a stock fell and how fast is a first step before you look at the news and the chart.
