My first earnings short-squeeze play is nutritional and personal care products maker Usana Health Sciences ( USNA), which is set to release numbers on Tuesday after the market close. Wall Street analysts, on average, expect USANA Health Sciences to report revenue of $172.40 million on earnings of $1.14 per share. The current short interest as a percentage of the float USANA Health Sciences is extremely high at 29%. That means that out of the 6.67 million shares in the tradable float, 1.95 million shares are sold short by the bears. This is a stock with a huge short interest and a very low tradable float. Any bullish earnings news could easily spark a monster short squeeze for shares of USNA post-earnings. >>5 Rocket Stocks to Buy Now From a technical perspective, USNA 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 $78.94 to its intraday high of $88.73 a share.

That move has now pushed shares of USNA within range of triggering a big breakout trade post-earnings.

Look for volume on that move that hits near or above its three-month average action of 128,383 shares. If that breakout triggers, then USNA will set up to enter new 52-week-high territory, which is bullish technical price action. Some possible upside targets off that breakout are $105 to $115 a share. I would simply avoid USNA or look for short-biased trades if after earnings it fails to trigger that breakout and then drops back below some near-term support at $85 a share to its 50-day moving average at $82.64 a share with high volume. If we get that move, then USNA will set up to re-test or possibly take out its next major support levels at $78.94 to $76 a share, or even $73 a share.
