NEW YORK (Real Money) -- Sell to buy, sell to buy. That's what this market is doing. It is churning at a pace that is pretty much completely mind-boggling, where everything that went up yesterday goes down today and we simply can't put good back-to-back days together.

A lot of this comes down to the dollar. We have had only two days of dollar weakness in a row, and that explains a lot of what you see. We know the dollar's going up, and if it doesn't go up today, then it will tomorrow. It really is like that, but who wants to flit in and out like this except hedge-fund managers who can sell every rally and buy every dip?

Of course, what will happen is today's the day you buy and the Fed just wrecks everything by dispelling the need to say it is being patient with rate hikes. Honestly, though, with that housing-start number, how could anyone not be patient? I know the weather was bad, but was it really that bad? No, and that's going to cause a lot of second-guessing.

In the meantime, only the now comically strong biotechs hold up and Regeneron (REGN) - Get Report is the total not-quit situation of all time.
