Top NYSE Short-Squeeze Plays

Updated from 10:07 a.m. EDT

Many investors are on the constant lookout for significant upward movement in stocks on a short-term basis. One way that an investor can make a quick gain is through a short-squeeze play.

A short squeeze takes place when a stock's short-sellers cover their positions quickly when good news boosts the price of the stock. This short-covering often drives the stock price even higher. The metric for measuring short-squeeze plays is the short ratio, which represents the number of days it would take a stock's short-sellers to cover their position based on the stock's recent average daily volume.
