An energy stock that insiders are snapping up a decent amount of shares in here is Endeavour International ( END), an independent oil and gas company engaged in the production, exploration, development and acquisition of crude oil and natural gas in the U.K. North Sea and U.S. Onshore. Insiders are buying this stock into major weakness, since shares are off by 64% in the last six months. Endeavour International has a market cap of $143 million and an enterprise value of $889 million. This stock trades at a cheap valuation, with a forward price-to-earnings of 7.30. Its estimated growth rate for this year is -90.8%, and for next year it's pegged at 116%. This is not a cash-rich company, since the total cash position on its balance sheet is $75.72 million and its total debt is $825.43 million. A beneficial owner just bought 250,000 shares, or about $884,000 worth of stock, at $3.53 to $3.56 per share. From a technical perspective, END is currently trending well below both its 50-day and 200-day moving averages, which is bearish. This stock has been downtrending badly for the last six months, with shares dropping from its high of $10.02 to its recent low of $2.95 a share. During that downtrend, shares of END have been consistently making lower highs and lower lows, which is bearish technical price action. That said, shares of END have entered extremely oversold territory, since its current relative strength index reading is now 18.18. Oversold can always get more oversold, but an extreme reading like this is often an area where a stock can experience a powerful bounce higher from. Traders who are bullish on END should now look for long-biased trades as long as it's trending above today's low of $2.95, and then once it manages to break out above some near-term overhead resistance at $3.50 a share with high volume. Look for a sustained move or close above $3.50 a share with volume that registers near or above its three-month average action of 806,297 shares. If that breakout triggers soon, then END could easily rebound back towards its next major overhead resistance levels at $4.50 to $5 a share, or even its 50-day moving average at $5.33 a share.
