>>5 "Magic Formula" Stocks for 2013

Stocks that are making large moves like these are favorites among short-term traders because they can jump into these names and try to capture some of that massive volatility. Stocks that are making big-percentage moves either up or down are usually in play because their sector is becoming attractive or they have a major fundamental catalyst such as a recent earnings release. Sometimes stocks making big moves have been hit with an analyst upgrade or an analyst downgrade.

Regardless of the reason behind it, when a stock makes a large-percentage move, it is often just the start of a new major trend -- a trend that can lead to huge profits. If you time your trade correctly, combining technical indicators with fundamental trends, discipline and sound money management, you will be well on your way to investment success.
