1. Town Sports International Holdings Inc (CLUB): Insider purchases have been going on here for the past one-and-a -half months. This is one of the two stocks we added into our hypothetical portfolio in November. Since then the stock went up by 23%. Currently it trades around $3.71. One insider, Bruce Bruckmann, purchased nearly 27,000 shares at $3.65-$3.70 on Tuesday. 2. World Heart Corp (WHRT): AWM Investment Company has been buying this company. It's a very illiquid stock. We are staying away from this one. 3. Bank of America ( BAC): E. Donald Powell initially purchased 5,000 shares at the beginning of December at $11.30. Last Friday, he purchased another 5,000 shares at $12.79. 4. Scientific Games Corp (SGMS): Insiders seem to be done with their purchases. They paid as high as $9.75 for SGMS , and the stock trades at $9.42. Jim Cramer didn't recommend buying the stock last week in Mad Money. Nevertheless, we are sticking with the insiders here.
