The mystery of

Nokia

(NOK) - Get Report

continues. That rally, starting at 3 p.m. in New York when the stock was at 174, took the company's stock to 184 in one hour! A close look at the trading during that hour reveals that no single large trade moved the stock. In fact, it was concentrated buying of the 2,000- and 4,000-share variety. In other words, this stock went up on nothing big at all. You would have expected to find some giant block trades of the 50,000 to 100,000 variety to move up a large-cap stock like this.

I figured that maybe there was a heavyweight buyer over in Finland, and New Yorkers were simply, and illegally, front-running him. Not true. The stock opened down 4 in Helsinki and then traded up ever so slightly to 180. No big buyer there.

So what happened? I think someone wanted this stock higher and simply bought it in a series of staccato, Gatling-gun purchases. I could be wrong. But this kind of manipulation up doesn't make the markets better; it makes them worse.

Forgive me for worrying what the downside would look like, but I don't like coming in on top of what has to now be regarded as a most shaky foundation and then having it pulled out from under me. Knowing and remembering the foundations and their makeup, shale, clay, granite or water have made me a boatload. Nokia is one of my favorite stocks, but I don't like those last 10 points. They can't support a run to 200 that I was hoping for before this one rested.
