They make sense to me. Sell earthmovers, sell rock companies, sell sheetrock companies. Sell Home Depot ( HD) and Black & Decker ( BDK). But what happens if the Fed is done raising rates? Do you buy them back? Can you get in them lower? And what happens if the companies you sell aren't all that in bed with housing? Do you really need to sell every share of the Caterpillars ( CAT) and the Ingersoll Rands ( IR) because of housing? That's what's happening. (I saw the same thing happen yesterday in autos. Everyone knows autos are slow. But did it suddenly just dawn on everyone who owns Johnson Controls ( JCI) that the company is in the auto business?) I believe companies like Masco ( MAS), Fortune Brands ( FO) and American Standard ( ASD) have more going for them than a D.R. Horton ( DHI) or Lennar ( LEN). I could be wrong, and I am definitely wrong when it comes to the stocks ... for now. But six months from now, I bet these stocks are higher, not lower. And remember, stocks aren't always that savvy. Think of Procter & Gamble ( PG) at $53 and being given away a few months ago. Think of Altria ( MO) forever at $70. Yeah, short-term stocks get it wrong all of the time. But to write off every company that has a housing component is just plain stupid. Yet, that's what is happening.
