One renewable energy stock where insiders have been active in is FutureFuel ( FF), which engages in the manufacture and sale of specialty chemicals and biofuels in the United States and internationally. It operates in two segments: chemicals and biofuels. Insiders are still finding value in this stock after it has run-up of over 85% so far in 2011. This company has a market cap of $500 million and an enterprise value of $369 million. FutureFuel is a cash-rich company, with over $131.38 million in cash on its balance sheet and zero debt. A director just bought 49,047 shares, or $598,673 worth of stock, at $12.21 per share. From a technical standpoint, this stock is currently trading just below its 50-day moving average of $12.75 a share. This stock recently failed to breakout above $13.75 a share and traded down to a low of $11.81 a share. That $11.80 area has held so far and looks to be a major near-term support level. If you're interested in buying this stock, I would wait until it moves back above the 50-day moving average on strong volume. Look for volume that's well above the three-month average action of 80,600 shares. I would add to any long positions if the stock stakes out $13.75 and then add again on a breakout above $13.99 a share.
