Another potential earnings short-squeeze trade is global high-technology filtration player Polypore International ( PPO), which is set to release its numbers on Wednesday after the market close. Wall Street analysts, on average, expect Polypore International to report revenue of $175.90 million on earnings of 40 cents per share. The current short interest as a percentage of the float for Polypore International is extremely high at 32.7%. That means that out of the 42.70 million shares in the tradable float, 15.23 million shares are sold short by the bears. If the bulls on Polypore International get the earnings news they're looking for, then this stock could explode higher post-earnings as the bears rush to cover some of their bets. >>3 Big Tech Stocks to Trade (or Not) From a technical perspective, PPO is currently trending above both its 50-day and 200-day moving averages, which is bullish. This stock has been uptrending for the last few weeks, with shares moving higher from its low of $36.80 to its recent high of $42.68 a share. During that move, shares of PPO have been mostly making higher lows and higher highs, which is bullish technical price action. That move has now pushed shares of PPO within range of triggering a major breakout trade. If you're in the bull camp on PPO, then I would wait until after its report and look for long-biased trades if this stock manages to break out above some near-term overhead resistance levels at $42.68 to $43.13 a share and then once it clears more resistance at $44.27 a share with high volume. Look for volume on that move that hits near or above its three-month average volume of 478,000 shares. If that breakout triggers, then PPO will set up to re-test or possibly take out its next major overhead resistance levels at $48.50 to $55 a share. I would simply avoid PPO or look for short-biased trades if after earnings it fails to trigger that breakout and then drops back below both its 50-day at $39.66 a share and its 200-day at $38.32 a share with high volume. If we get that move, then PPO will set up to re-test or possibly take out its next major support levels at $36.80 to $35.10 a share.
