Updated from 7 a.m. EDTThe recent stock market volatility has created significant short-squeeze opportunities. A short squeeze takes place when a stock's short-sellers scramble to cover their bearish positions when that stock moves sharply upward; their buying ends up pushing shares even higher. Short positions of stocks are measured by the short-squeeze ratio, which represents the number of days it would take for the short-sellers to cover their positions based on the recent daily volume of the stock.
