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 AeroVironment (Nasdaq: AVAV) flying past the pros undetected. The maker of unmanned aircraft systems posted a fiscal second quarter profit of $0.30 a share, a 30-fold gain from the mere $0.01 a share that it posted a year earlier. More importantly for our purposes, analysts were only banking on net income of $0.20 a share.

I guess it pays to make military products that keep human lives out of harm's way, since PackBot maker iRobot (Nasdaq: IRBT) has been consistently landing ahead of Wall Street's projections for two years.

Titan Machinery (Nasdaq: TITN) also harvested a bountiful quarter. The farm equipment retailer planted a quarterly profit of $0.61 a share, well ahead of the $0.50 a share that the pros were expecting. Titan also raised its guidance. Rising food prices translate into farmers investing more in their agricultural pursuits.

Finally, we have Vera Bradley (NYSE: VRA) on the move. The maker of fashionable handbags, suitcases, and accessories rang up a profit of $0.32 a share. Analysts were only targeting net income of $0.28 a share. Since going public 14 months ago, Vera Bradley is 4-for-4 in beating Wall Street estimates on the bottom line. Happy travels!  

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.
