Don't settle for ordinary quarterly reports.

I take a look at three companies that beat market expectations every week, since I believe that it's the biggest factor in a stock beating the market. Leaving Wall Street's pros with stunned expressions can be a good thing. It usually means that the companies have more in the tank than analysts figured. Capital appreciation typically follows.

Let's take a look at a few companies that humbled the prognosticators over the past few trading days.

We can start with Select Comfort (Nasdaq: SCSS). Shares of the company behind the Sleep Number air-chambered mattresses gave its shareholders a peaceful night's sleep by earning $0.13 a share in its latest quarter. Select Number's bottom-line performance is well ahead of both the $0.08 a share it earned a year earlier and the $0.11 a share that analysts were targeting.

It was easy to see Select Comfort's strong performance coming. Rival Tempur-Pedic (NYSE: TPX) and home furnishings bellwether Bed Bath & Beyond (Nasdaq: BBBY) also landed ahead of the pros by double-digit percentage point margins in their most recent quarters.

Chipotle Mexican Grill (NYSE: CMG) is also chomping down the pros like a hungry patron eating one of the quick-service chain's signature burritos. Earnings per share soared 49% to $1.47 a share, fueled by a robust 12.6% spike in same-store sales for the quarter.

Analysts were banking on a mere $1.29 a share profit out of the burrito roller, but what else is new? Wall Street's been sorely underestimating Chipotle's earnings potential all year.

Finally we have Whole Foods Market (Nasdaq: WFMI) checking out nicely. The organic grocer's quarterly net income of $0.51 a share was considerably better than the $0.46 a share that investors were expecting. Whole Foods' strong report also sent shares of rival upscale grocer The Fresh Market (NYSE: TFM) nicely higher last week.

It's important to keep watching the companies that surpass expectations. Over time, it will be a lucrative experience for investors as the market rewards the overachievers.
