Monday
The new trading week starts off with a nickel-and-dime-store juggernaut giving you its two cents' worth. Dollar General (NYSE:DG) earned $0.46 a share in its fiscal fourth quarter last year. This time around, analysts expect the company to come in a few pennies shorter, at $0.38 a share. Don't hold out for much more than that; Dollar General has missed Wall Street's targets in three of the past four quarters.

Tuesday
If it's Tuesday, it must be time to put on your game face; this time, video game retailer GameStop (NYSE:GME) will be stepping up to play. The Stock Advisor recommendation has held up well in recent quarters. Even though video game sales often hit a lull when new consoles are introduced -- they don't peak for another three to four years, when the systems have a wider user base -- GameStop has beaten the trend, thanks to its lucrative business of selling used games, systems, and accessories at generous markups.

Wednesday
Payroll processor Paychex (NASDAQ:PAYX) will have its shareholders hoping for payday on Wednesday. The company knows a thing or two about mailing out checks. We toasted the stock last summer, noting that among S&P 500 companies, only Intel (NASDAQ:INTC) had raised its dividends by a greater percentage.

Thursday
Next, we go lemon hunting at CarMax (NYSE:KMX). Those sour lemons won't be easy to find, though. CarMax is pretty particular about the maintenance of its used cars. Buyers and sellers know it, too, making the company a standout in the auto retailing industry. Analysts expect earnings to grow to $0.42 a share, but have you seen how the company has burned rubber over the pros' estimates in the past few quarters? CarMax has beaten expectations by anywhere from $0.09 to $0.17 per share in each of the last three quarters.

The test drive has rewarded investors, as CarMax's shares have nearly doubled since being singled out in Inside Value 15 months ago. Talk about getting some good mileage out of that pick!

Friday
Come Friday, you'll understand why I'm not telling you to back up the used truck on CarMax before Thursday's report. Why? Well, Global Payments (NYSE:GPN) reports on Friday. Back in January, I was singing the company's praises after it beat analyst estimates for 17 consecutive quarters. Alas, the streak died a few weeks later. Then again, we can't get steamed just because the financial-transaction processor merely met Wall Street's profit target. Let's not get too greedy, especially with the weekend just around the corner.

Until next week, I remain,
