I told you we couldn't do that But the good news for SeaDrill hasn't spread to the entire industry. Hercules Offshore (Nasdaq: HERO) shares were hit hard last week when the company said the Securities and Exchange Commission and Department of Justice had opened an investigation into the company. Hercules was hit harder than most by a slowdown in the Gulf of Mexico, and with shares rocketing higher over the last six months the investigation may have put a crunch on momentum. Plus Hercules doesn't play in the increasingly valuable ultra-deepwater drilling space.
