One final stock in the oil and gas complex where insiders are buying up stock in is AmeriGas Partners ( APU). This company is a retail propane distributor in the United States. Insiders are buying into some weakness here since the stock is down 11% so far in 2012. AmeriGas Partners has a market cap of $3.5 billion and an enterprise value of $4.5 billion. This stock trades at a fair valuation, with a trailing price-to-earnings of 22.79 and a forward price-to-earnings of 18.72. Its estimated growth rate for next quarter is -300%, and for this year it's pegged at -103%. This is not a cash-rich company, since the total cash position on its balance sheet is $58.76 million and its total debt is a whopping $1.16 billion. A chairman of the board and director just bought 4,000 shares, or $161,000 worth of stock, at $40.29 per share. >>6 Small-Cap Stocks to Fuel Your Portfolio From a technical perspective, APU is currently below both its 50-day and 200-day moving averages, which is bearish. This stock recently dropped big from around $45 to a low of $39.60 a share on monster volume. Since that sizeable decline, APU has been able to hold above that $39.60 low, and it has trended higher and moved within near-term breakout range. If you're bullish on APU, I would look for long-biased trades once this stock triggers a near-term breakout above $41 a share with high volume. Look for volume on a move above that level that registers near or well above 287,474 shares. If we get that action soon, then look for APU to make a solid pop back towards its 200-day at $42.53 or its 50-day at $43.20 in the very near future. I would simply avoid any long biased trades on APU if this stock trends back below that recent low of $39.60 with high-volume.
