Another technology player that insiders are active in here is Acorn Energy ( ACFN), which provides digital solutions for energy infrastructure asset management. Insiders are buying this stock into major weakness, since shares are off by 56% so far in 2013. >>5 Dogs of the Dow to Stomp the Market Acorn Energy has a market cap of $62 million and an enterprise value of $45 million. This stock trades at a reasonable valuation, with a price-to-sales of 2.98 and a price-to-book of 1.56. Its estimated growth rate for this year is -11.8%, and for next year it's pegged at 50%. This is a cash-rich company, since the total cash position on its balance sheet is $13.35 million and its total debt is just $251,000. This stock currently sports a 4.3% dividend yield. A director just bought 80,000 shares, or $228,000 worth of stock, at $2.85 per share. From a technical perspective, ACFN is currently trending below both its 50-day and 200-day moving averages, which is bearish. This stock has been downtrending badly for the last four months, with share plunging from its high of $9.90 to its recent low of $2.85 a share. During that downtrend, shares of ACFN have been consistently making lower highs and lower lows, which is bearish technical price action. That said, shares of ACFN have now entered oversold territory, since its current relative strength index reading is 33.31. Oversold can always get more oversold, but it's also an area where a stock can rebound sharply higher from. If you're in the bull camp on ACFN, then look for long-biased trades as long as this stock is trending above some near-term support at $3.21 and then once it breaks out above some near-term overhead resistance at $3.59 a share with high volume. Look for a sustained move or close above that level with volume that hits near or above its three-month average action of 213,249 shares. If that breakout triggers soon, then ACFN will set up to re-test or possibly take out its next major overhead resistance levels at $4.50 to its 50-day moving average at $5.37 a share. This stock could even hit $6 if we see big volume move in here on that breakout.
