In the electronic instrument and controls complex, insiders are buying up some stock in Comverge ( COMV), a provider of intelligent energy management. This stock is off to a strong start in 2011, with shares up over 12%. Comverge has a market cap of $35.4 million and an enterprise value of $36.4 million. This stock trades at a price-to-sales of 0.25 and a price-to-book of 1.12. Its estimated growth rate for this year is 47.2%, and for next year it's pegged at 59.7%. This is not a cash-rich company, since the total cash position on its balance sheet is $25.5 million and its total debt is $27 million. A beneficial owner just bought 550,100 shares, or about $707,000 worth of stock, at $1.23 to $1.40 per share. From a technical standpoint, COMV is currently trading above its 50-day moving average and below its 200-day moving average, which is neutral trendwise. This stock dropped from its October high of $1.98 to a recent low of $1.03 a share. Since hitting that low, the stock has rebounded sharply to its current price of $1.42 a share. As this stock has uptrended to its current price it has been making higher highs and higher lows, which is bullish price action. If you're bullish on COMV, I would look to buy the next big breakout, which will trigger when this stock takes out $1.48 to $1.49 with volume. Look for volume that registers near or above its three-month average action of 145,410 shares. I would simply use a mental stop that's just below its 50-day moving average of $1.35 in case the breakout fails. That's also a great stop to use if you buy off weakness and anticipate the breakout.
