Stock action is not always sensible nor predictable even with good stats to back it up. MMs can appreciate a certain degree of uncertainty in the air. Don't underestimate them. All investing is risky, least amount of risk is to get the best picture available of what it is you are investing in and then hold until you are comfortable selling. In my opinion, looking at an investment is a long term undertaking, otherwise it seems like casual betting to follow the momentum money trail.
