One final earnings short-squeeze idea play is aerospace and defense player Heico ( HEI), one of TheStreet Ratings' top-rated aerospace and defense stocks, which is set to release its numbers on Thursday after the market close. Wall Street analysts, on average, expect Heico to report revenues of $192.69 million. If you're looking for a strong uptrending stock ahead of the quarter, then take a strong look at shares of Heico. This stock has returned over 40% so far in 2011, and its currently trading just three points off of its 52-week high of $60.94 a share. The current short interest as a percentage of the float Heico is very high at 29.1%. That means that out of the 33.61 million shares in the tradable float, 3.37 million are sold short by the bears. This is a huge short interest on a stock with a reasonably low float. Any bullish earnings news should set this stock off for a monster short-squeeze. From a technical standpoint, HEI is currently trading above both its 50-day and 200-day moving averages, which is bullish. This stock hit a low in October at $45.18 a share, and since then, it has been uptrending strong making mostly higher highs and higher lows. Now HEI is setting up for a big breakout post-earnings if the company can report earnings that the bulls love. If you're bullish on HEI, I would wait until after its report and buy the stock as long as it stays above its 50-day moving average of $56.42 a share. If that level holds, I would then add aggressively once HEI triggers a major breakout above $60.50 to $60.94 on heavy volume. Look for volume that registers close to or above its three-month average action of 195,625 shares. I would short or avoid HEI after its earnings report only if the stock drops back below its 50-day of $56.42 on heavy volume. If that level is taken out post-earnings, then target a drop back towards the 200-day moving average of $51.79 a share, or possibly even lower if the bears gain control of this stock.
