If a stock's price begins to rise significantly, investors who have short sold the stock will quickly begin to close out their positions (by purchasing shares off the open market), creating buying pressure for the stock and driving the price up even more. If a previously lagging stock turns very bullish, the buying action of short sellers can result in extra upward momentum and increased losses for short sellers who are slow to close out their positions. The longer the days to cover, the more pronounced this effect can be.
