What It Means: Over the years, I have often looked for stocks that have a high short-interest ratio as well as bullish volume and chart patterns. The high short interest in many cases has accentuated the price move.

Since I continue to think the overall market is vulnerable at current levels, I would look to buy these stocks close to good support where tight stops can be used.
