BALTIMORE ( Stockpickr) -- It's a market of stocks, not a "stock market."

As overused as that phrase may be, there's some truth to it. And as we approach the first trading session in March, we're seeing some stellar examples of why paying attention to that market of individual stocks could save your portfolio's performance in 2013.

As I write, the S&P 500 is up 6.3% on the first two months of the year. No matter how you slice it, that's some stellar performance, especially if that market momentum can hold strong as 2013 progresses. But not all stocks are taking full advantage of the rally. In fact, some of the biggest names are looking downright scary right now -- and investors who think they're getting market-matching performance out of those names are going to be unpleasantly surprised.

So today we're taking a technical look at the bearish price setups forming in five of the biggest names on Wall Street.

If you're new to technical analysis , here's the executive summary.

Technicals are a study of the market itself. Since the market is ultimately the only mechanism that determines a stock's price, technical analysis is a valuable tool even in the roughest of trading conditions. Technical charts are used every day by proprietary trading floors, Wall Street's biggest financial firms, and individual investors to get an edge on the market. And research shows that skilled technical traders can bank gains as much as 90% of the time.

Every week, I take an in-depth look at big names that are telling important technical stories. Here's this week's look at the charts of five high-volume stocks to trade for gains .

Up first is PetroChina (PTR) , the $252 billion Chinese oil and gas giant. PTR has turned out some uninspiring performance in the last year, slipping around 7% in those 12 months while the rest of the broad market rallied. And now investors looking for more upside had better keep looking.

That's because PTR is currently forming a double top pattern, a setup that's formed by two swing highs that top out at approximately the same price level. PetroChina's first top came in back in October, and shares topped out for their second time in January. The sell signal for this setup comes on a breakdown through support at $130. If PetroChina can't catch a bid below that support level, you don't want to own it.

Momentum adds some extra evidence for downside in PetroChina. 14-day RSI broke its long-term uptrend at the start of this month, and it's been trending lower ever since. Since momentum is a leading indicator of price, that's an important indication that shares are losing steam at an increasing pace. While I wouldn't recommend unloading shares unless $130 gets taken out, traders will want to keep a close eye on this name in March. Exxon Mobil
