From a technical perspective, FRX is currently trading above both its 50-day and 200-day moving averages, which is bullish. Shares of FRX recently sold off from a high of $36.44 to a low of $31.28 with some above average selling volume. Following that low, shares of FRX have started to ramp higher and move back above both its 50-day and 200-day moving averages. That move has now pushed FRX back inside of its uptrend that had been intact before the recent selloff. If you're bullish on FRX, then I would look for long-biased trades as long as this stock is trending above its 50-day moving average of $34.40 with strong upside volume flows. I would consider any upside volume day that registers near or above its three-month average volume of 1.9 million shares as bullish. If FRX can maintain that trend, then this stock has a great chance of re-testing and possibly taking out its recent high of $36.44 a share. On the flipside, I would avoid FRX or look for short-biased trades if this stock fails to hold that trend, and then drops back below some near-term support at $33.50 a share with heavy volume. If we see that action soon, then look for FRX to re-test and possibly take out its 200-day moving average of $32.80 a share.
