That's the homie sector ETF and, yes that's a cross over. What I like about this cross over and I don't like about the one several days ago on 05/09 is that this one was preceded by a BOB formation too. And that is an excellent entry into the cross over.

I'm not suggesting that you run out and get some - but I'd certainly keep an eye on XHB for awhile and if you get a weekly cross you might want to get real re: real estate.
