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, the week prior, and the week before that, the ethanol producers were retreating faster than the hairlines at Rogaine headquarters -- and they're still the Fools at the bottom of the hill. Stocks in this sector are down 7.9% over the last 30 days.

Who are the others? Have a look:

  • Second worst are the optical components makers. Riding the light has brought forth dark times for stocks like Avanex (NASDAQ:AVNX) and Finisar (NASDAQ:FNSR), which are down by 7.4% over the past 30 days.
  • Third worst, and on the list for the second straight week, are distillers. Still too drunk to produce returns, bottle-tippers like Willamette Valley Vineyards (NASDAQ:WVVI) are down 6.3% over the past 30 days.

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