Welcome back to another Foolish review of the coldest stocks as ranked by Motley Fool CAPS. We're looking at the three worst-performing industries over the past 30 days and your favorite short and long candidates in each.

Last week and for the four weeks prior, ethanol producers led the retreat. But not this week. This time, bio-pharmaceuticals are colder than a hairless cat in the Arctic. Biotechs as a group are down 9.3% over the past 30 days.

Who are the others? Have a look:

  • Second worst are -- surprise! -- ethanol producers. Investors have lost the taste for steamed corn stocks like MGP Ingredients (NASDAQ:MGPI), which, as a group, are down 7.6% over the past 30 days.
  • Third worst are the tax services firms, whose returns have been, shall we say, lacking. Stocks in this sector, as a group, are down 5.5% over the past 30 days.

According to you, our Foolish readers, the worst stocks in these industries to own now -- i.e., those rated one or two out of a maximum five stars in CAPS -- are:
