Don't settle for ordinary quarterly reports.

Every week, I take a look at three companies that beat market expectations, 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 Mosaic (NYSE: MOS) making fertilizer out of Wall Street's estimates. The potash specialist delivered a quarterly profit of $1.40 a share, topping the $1.28 a share the pros were targeting.

But Mosaic's strong showing wasn't enough to escape an analyst downgrade. Citi prefers the faster growth and comparable valuation of CF Industries (NYSE: CF), making it the analyst's top pick in the fertilizer space at the expense of downgrading Mosaic.

Shares of Xyratex (Nasdaq: XRTX) approached a 52-week high -- rising every trading day last week -- as the data storage company thumped Mr. Market's expectations. No one figured that Xyratex would come even close to the $0.69 a share that it rang up a year earlier, but it did.

Xyratex's fiscal-fourth-quarter profit of $0.73 a share was more than twice the $0.33 a share that Wall Street was forecasting.

Finally we have Landec (Nasdaq: LNDC) parlaying polymer into a plumper profit. Landec's quarterly net income of $0.13 a share landed just ahead of the $0.12 a share the pros were banking on.

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.
