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 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 pros over the past few trading days.

We can start with SanDisk (Nasdaq: SNDK).

There was plenty of pessimism heading into the flash memory leader's quarterly report, especially after SanDisk had warned of sluggish demand relative to production in its previous report.

Well, the $0.21 a share that SanDisk earned was well short of its performance a year earlier, but it was more than enough to land ahead of the $0.18 a share that worrywart analysts were forecasting. A rosier outlook for the balance of the year should get Wall Street back on track.

Select Comfort (Nasdaq: SCSS) was another winner that had to overcome looming pessimism. The company behind the Sleep Number air-chambered beds saw rival Tempur-Pedic (NYSE: TPX) get slammed several weeks ago after posting uninspiring results.

Select Comfort also took a hit on Tuesday after retailer Mattress Firm (Nasdaq: MFRM) slashed its full-year sales forecast.

Well, Select Comfort's profit of $0.30 a share a day later -- besting the $0.27 a share where the pros were napping -- was enough to send the stock higher.

Finally, we have Joe's Jeans (Nasdaq: JOEZ) fitting in nicely. The premium denim company -- fueled by a 16% increase in sales and an impressive 10% pop in retail comps -- cranked out a profit of $0.02 a share. That may not seem like much, but it was twice as much as the market was expecting.
