A director just bought 5,000 shares, or about $204,000 worth of stock, at $40.99 per share. From a technical perspective, L is currently trending above its 200-day moving average and just below its 50-day moving average, which is neutral trendwise. This stock has been downtrending for the last month and change, with shares dropping from a high of $43.29 to a recent low of $39.50 a share. During that move, shares of L have been mostly making lower highs and lower lows, which is bearish technical price action. That said, shares of L have started to rebound off that $39.50 low and are now trading within range of triggering a near-term breakout trade. If you're bullish on L, then I would look for long-biased trades once this stock manages to break out above some near-term overhead resistance at its 50-day of $41.43 a share with high volume. Look for a sustained move or close above its 50-day with volume that registers near or above its three-month average action of 946,013 shares. If that breakout triggers soon, then L will set up to re-test or possibly take out its next major overhead resistance levels at $42.50 to $43 a share.
