The run up in their stock prices has been massive, and current sentiment is the highest in quite some time. That is precisely why they are excellent short candidates. I particularly like a short of KBH at today's close of $16.15. They will all come back to reality when the decline in the major averages begins. Target price for KBH: $7-. This is a high probability trade.
A rise in long term interest rates?
It has somehow been forgotten here that the markets themselves can dictate interest rates without official FED approval. At a certain point, coming soon, a risk premium will be assigned to our Treasury bonds, no matter our unemployment rates. The risk will be expressed as an increase in the interest yield. It would only take a decrease in Treasury purchases by the Chinese, who have problems of their own, but are increasingly hip to the Fed's ponzi scheme. If you think none of this is true, ask the Greeks, the Italians, or the Spanish.
