One airline player that insiders are warming up too here is United Continental ( UAL), which transports people and cargo through its mainline operations, which utilize jet aircraft with at least 110 seats, and its regional operations. Insiders are buying this stock into some decent weakness here, since shares are off by around 21% so far in the last six months. United Continental has a market cap of $6.05 billion and an enterprise value of $10.74 billion. This stock trades at a reasonable valuation, with a trailing price-to-earnings of 15.56 and a forward price-to-earnings of 3.53. Its estimated growth rate for this year is 1.7%, and for next year it's pegged at 45.4%. This is not a cash-rich company, since the total cash position on its balance sheet is $7.7 billion and its total debt is $12.45 billion. The CEO and president just bought 55,600 shares, or about $1 million worth of stock, at $18.00 per share. The vice president also just bought 13,500 shares, or about $247,000 worth of stock, at $18.30 per share. From a technical perspective, UAL is currently trading below both its 50-day and 200-day moving averages, which is bearish. This stock recently formed a triple top chart pattern at around $24.79 to $24.95 a share. Following that top, shares of UAL plunged dramatically all the way down to its recent low of $17.45 a share. During that massive slide lower, shares of UAL were consistently making lower highs and lower lows, which is bearish technical price action. >>5 Big Stocks Ready to Pay You Bigger Dividends If you're bullish on UAL, then I would only look for long-biased trades once this stock manages to trigger a near-term breakout trade above some overhead resistance at $18.37 a share with high volume. Look for volume on that move that hits near or above its three-month average action of 5.3 million shares. If that breakout triggers soon, then I would look for a tradable bounce back towards its 50-day moving average of $21.05 a share. On the flipside, I would avoid UAL or look for short-biased trades if this stock fails to gain any traction on the upside, and then drops below some major near-term support at $17.45 with high volume. Any high-volume moves below $17.45 a share should setup UAL to re-test its 52-week low of $15.51 a share.
