To invest, or not to invest: that is the question.

SmartMoney reports that Market Profile Theorems, which tracks insider moves, is now bearish on the energy sector, and rather bearish on the market as a whole. (I'm in agreement with them on the second part.)

Amusingly, however, their top stock pick is Kerr-Mcgee (KMG), and their top industries includes utilities - natural gas. (Carl Icahn's in agreement with them on the first part.)

I'm of the opinion that insider buys tend to be better signals than sells on individual stocks, but sales in large scale can be very convincing calls to get out as well.
