Another potential earnings short-squeeze trade is technology-based education player K12 ( LRN), which is set to release numbers on Thursday before the market open. This company offers curriculum and educational services designed to facilitate individualized learning for students in kindergarten through 12th grade. Wall Street analysts, on average, expect K12 to report revenue of $165.39 million on a loss of 3 cents per share. This stock has been off to a hot start so far in 2012, with shares up over 30%. Despite that hot start, shares of K12 are trending well off its 52-week high of $37 a share as we move close to its earnings report. >>10 Companies That Prove Stock Picking Is Still Alive The current short interest as a percentage of the float for K12 is extremely high at 41.1%.

If you're bullish on LRN, then I would wait until after its report and look for long-biased trades if this stock can manage to take out some overhead resistance levels to $23.94 to $25.39 a share with high volume. Look for volume on that move that registers near or above its three-month average action of 250,186 shares. If we get that breakout, then look for LRN to re-test and possibly take out its next major overhead resistance levels at $26.40 to $28.83 a share. I would avoid LRN or look for short-biased trades if after earnings it fails to trigger that breakout and then drops below its 200-day at $22 and its 50-day at $21.10 a share with heavy volume. If we get that action, then LRN will setup to re-test and possibly take out its next major support level at $20.28 a share.
