(IBM) - Get Report

. I think this stock could be the tell for where this market can go. IBM is the consummate cyclical tech name with great products and a terrific pedigree -- and a low price-to-earnings ratio.

IBM has, in the vernacular of the bulls, $6 in earnings power. It is reasonable to think that IBM can get a 25 multiple for those earnings.

In other words, it is reasonable that IBM can go to $150. I think this stock has played a leadership role off the bottom in September, having bottomed at $90 at the same time that the market bottomed. This stock has everything the bulls need in a company: earnings power, buyback, interesting new products and leverage to a recovery.

As long as this stock is moving up I don't want to get off this bull, and I don't care how much bucking and goring will be done in the ensuing drive to $150.

Those of you who like to watch stocks as tells, this should be your No. 1 tell. If it rolls over, you are going to have to be careful.

As long as it is "all systems go" to $150, though, you want to be longthis market.
