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 Kroger (NYSE: KR). The grocer managed to post double-digit growth in revenue and earnings, as the chain passed on rising food costs and patrons didn't flinch. Kroger's quarterly profit of $0.70 a share comfortably exceeded the $0.64 a share that analysts had in their carts.

Majesco Entertainment (Nasdaq: COOL) also bested Mr. Market. The video game maker's hit Zumba Fitness musical workout title helped reverse a year-ago loss with net income of $0.13 a share. Wall Street was expecting Majesco to earn roughly half as much, but it's not the only video game company to land ahead of the pros lately. THQ (Nasdaq: THQI), Take-Two Interactive (Nasdaq: TTWO), Electronic Arts (Nasdaq: ERTS), and Activision Blizzard (Nasdaq: ATVI) have all surpassed bottom-line estimates in their latest quarters.

Finally, we have Best Buy (NYSE: BBY) ringing up a quarterly profit of $0.35 a share in its latest fiscal quarter. Analysts banked on $0.33 a share in net income.

I still have my concerns with Best Buy. The consumer electronics retailer earned more a year earlier, and same-store sales have also been negative in each of the past three quarters. This may be a relative victory, but it's far from an absolute one.

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.
