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 Coinstar (Nasdaq: CSTR). The company behind the Redbox DVD rental kiosks cranked out an adjusted quarterly profit of $0.46 a share, more than twice the $0.22 a share that analysts were expecting.

It was a strong showing for the company that was already gaining momentum after massive Blockbuster store closures improved its near-term fundamentals. Netflix (Nasdaq: NFLX) and Coinstar may have been the butt of Tinseltown jokes after agreeing to 28-day freezes on new releases from some studios last year, but both fast-growing companies are having the last laugh now.

Exxon Mobil (NYSE: XOM) earned its right to command the country's chunkiest market cap with its fueled up profitability. The oil giant earned $2.14 a share in its latest quarter, ahead of the $2.07 a share that Wall Street was targeting.

Exxon Mobil's win may seem like a no-brainer in this age of soaring gasoline prices, but it's never that easy. The pros model the pain at the pump. Chevron (NYSE: CVX) also landed ahead of the Mr. Market's guesstimates, but Valero (NYSE: VLO) actually fell short on the bottom line.

Finally, we have China's Sohu.com (Nasdaq: SOHU) coming out on top. Sohu earned $1.01 a share in its latest quarter, boosted by strength in online display advertising, paid search, and its majority stake in web-based gamer Changyou.com (Nasdaq: CYOU). Investors figured that the new media darling would only score net income of $0.97 a share.

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.
