BALTIMORE ( Stockpickr) -- When everyone's opening presents this Christmas, it's no fun to get coal in your stocking. Likewise, when the market's sitting on new all-time highs this December, it's no fun to see "toxic" names drag your portfolio through the mud. >>5 Rocket Stocks to Buy Before 2014I like this market, and the evidence suggests that 2014 will tack on some respectable gains as well. But that doesn't mean that now's a good time to own all stocks. Laggard names are still poisonous to your portfolio in a bull market. Maybe more so. That's why we're taking a closer look at five "toxic" stocks you should be selling in December. To be fair, the companies I'm talking about today aren't exactly "junk." By that, I mean they're not next up in line at bankruptcy court. But that's frankly irrelevant; from a technical analysis standpoint, they're some of the worst positioned names out there right now. For that reason, fundamental investors need to decide how long they're willing to take the pain if they want to hold onto these firms this summer.

So without further ado, let's take a look at five toxic stocks you should be unloading.
