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 2014

I 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. And for investors looking to buy one of these positions, it makes sense to wait for more favorable technical conditions (and a lower share price) before piling in.

>>Buy the Dips: This Bull Market's Not Over

For the unfamiliar, technical analysis is a way for investors to quantify qualitative factors, such as investor psychology, based on a stock's price action and trends. Once the domain of cloistered trading teams on Wall Street, technicals can help top traders make consistently profitable trades and can aid fundamental investors in better planning their stock execution.

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

Cornerstone OnDemand

First up is Cornerstone OnDemand (CSOD), a $2.57 billion software stock that's been on a tear in 2013. Since the first trading session of the year, CSOD has rallied more than 69%. But the upside could be over thanks to a bearish setup that's been forming in shares.

CSOD is currently forming a descending triangle pattern, a bearish setup that's formed by a horizontal support level below shares at $46 and downtrending resistance to the upside. Basically, as CSOD bounces in between those two technical price levels, it's getting squeezed closer and closer to a breakdown below $46. When that happens, we've got a sell signal.

$46 gets some extra strength as a support level because it acted as resistance for shares on the way up back in the summer. The fact that buyers assigned some extra significance to $46 makes it a level that's worth watching on the way down. The 50-day moving average has been a good proxy for resistance on the way down. If you decide to bet against CSOD from here, that's where you'll want to keep a protective stop.

PNC Financial Services Group

Don't be fooled by the 30% premium on shares that $40 billion bank PNC Financial Services Group (PNC) commands today; the stock is starting to look "toppy" in the long-term here.

PNC is currently forming a double top, a bearish reversal pattern that's formed by two swing highs that top out around the same price level. The sell signal comes on a break below the trough that separates the two tops. For PNC, that support level comes into play at $70.50. If shares slip below that $70.50 level, we've got a sell signal.

Momentum, measured by 14-day RSI, adds some extra confidence to the topping setup in PNC. In the context of the long-term move, a drawn-out downtrend in RSI is still very much intact right now. Since momentum is a leading indicator of price, that's a signal that buying pressure is waning in shares of this big bank right now. Still, downside isn't a foregone conclusion until $70.50 gets violated.

Pearson

We're seeing the exact same setup in shares of UK-based education publisher Pearson (PSO), just in the shorter term. Pearson is showing a double-top of its own right now, with support at $20.75. If $20.75 gets taken out, it's time to be a seller in PSO.

>>5 Stocks Poised for Breakouts

Whenever you're looking at any technical price pattern, it's critical to think in terms of buyers and sellers. Triangles and double tops are a good quick way to explain what's going on in a stock, but they're not the reason it's tradable. Instead, it all comes down to supply and demand for shares.

That support level at $20.75 is a price where there had been an excess of demand of shares; in other words, it's a place where buyers were more eager to step in and buy shares at a lower price than sellers were to sell. That's what makes a breakdown below $20.75 so significant. The move would indicate that sellers are finally strong enough to absorb all of the excess demand above that price level. Wait for that trigger before you sell.

There's an abundance of gaps on Pearson's chart. Those gaps, called suspension gaps, are the result of off-hours trading on the London Stock Exchange. The gaps can be ignored from a technical standpoint.

CVR Refining

Meanwhile, it doesn't take an expert technical analyst to figure out what's going on in shares of $3.3 billion refinery stock CVR Refining (CVRR). This stock is showing traders about as simple a setup as it gets: a downtrending channel. With shares testing resistance this month, it's time to unload CVRR.

>>4 Stocks Breaking Out on Big Volume

CVRR's price channel has provided traders with a high-probability range for shares since the middle of the year. Despite the last four attempts at pushing through trendline resistance, shares have been swatted down on each attempt. A move all the way down to support looks likely at this point.

Relative strength has been bleeding off over the course of 2013, an indication that CVRR isn't just moving lower on an absolute basis, it's digging itself much deeper versus the broad market as the year progresses too. If you still own shares, selling now is likely to spare more of your capital from what's to come.

Revlon

Last up is $1.3 billion cosmetics name Revlon (REV). Despite a 72% rally since the calendar flipped over to January, Revlon is looking "toppy" from here in the long-term. That means that shareholders should start thinking defensively as REV moves lower into this week.

Revlon is currently forming a head and shoulders top, a bearish reversal setup that indicates exhaustion among buyers. The setup is formed by two swing highs that top out around the same level (the shoulders), separated by a bigger peak called the head; the sell signal comes on the breakdown below the pattern's "neckline" level, which is right at $23.50 at the moment for REV. If this stock can't catch a bid at $23.50, unload it.

REV's outperformance up to this point has been a byproduct of stellar relative strength for the first three quarters of the year. But that uptrend in relative strength broke back at the end of October, and shares have been giving points back ever since. The break in the relative strength line is a big signal that you don't want to own this stock anymore.
