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 pros over the past few trading days.

We can start with Cisco Systems (NASDAQ:CSCO).

The maker of networking equipment has an impressive streak going. By cranking out a profit of $0.48 a share in its latest quarter -- just ahead of the $0.46 a share that analysts were projecting -- Cisco stretches its streak of better than expected profitability to 19 consecutive quarters.

That's surprising. Cisco hasn't exactly been a market darling over the past five years. It's been a flop -- and a Flip -- with consumer products. Competition on the enterprise end has been fierce. However, Cisco has somehow managed to surpass Wall Street's pessimistic targets.

PetSmart (NASDAQ:PETM) also isn't going to the dogs. The pet supplies retailer saw its quarterly profit soar 50% to $0.75 a share, lifted by a healthy 6.5% increase in same-store sales. Analysts were only holding out for net income of $0.63 a share.

Finally, we have NQ Mobile (NYSE:NQ) making the right connection. The global provider of mobile Internet services is growing at a steady pace, with adjusted earnings climbing 16% to $0.16 a share for its latest quarter. Wall Street was settling for a profit of $0.15 a share. It's not much, but NQ Mobile had come up short the prior quarter and simply met expectations the period before that.
