If you ask because you're looking for a short play, none of these companies makes a good candidate. They've already been battered enough and upside potential, however unlikely, dwarfs what's left of the downside for these stocks.
An alternative you may want to consider is shorting homebuilders such as LEN, KBH, TOL, NDE, and BZH. While these stocks/companies have suffered as well, they have yet to realize the extent to which their bottom lines will be affected. The ailing real estate market is just the beginning. The real trouble rests in the increasingly stringent lending standards, which will eliminate the once insatiable appetite for cookie cutter complexes (100-1000 identical home projects).
