Other closed positions of interest include Westport Innovations Inc. (USA) (NASDAQ:WPRT) and Zynga Inc (NASDAQ:ZNGA). Westport Innovations Inc. (USA) (NASDAQ:WPRT) has been designing engines powered by natural gas, including some heavy trucks. Bulls like its plans to expand in China and the nation’s expanding network of fueling stations. But the company remains unprofitable, and it just issued a poor earnings report and lowered guidance, sending its shares down and getting downgraded on Wall Street.

Online gaming specialist Zynga Inc (NASDAQ:ZNGA) also posted poor results recently, and compounded them by shuttering its real-money gaming plans. The company has been diversifying its revenue stream away from key partner Facebook, but it’s in the red. Think twice before jumping into these shares. Watching and waiting might be the best move.

We should never blindly copy any investor’s moves, no matter how talented the investor. But it can be useful to keep an eye on what smart folks are doing. 13F forms can be great places to find intriguing candidates for our portfolios.
