The new trading week kicks off with GT Solar (Nasdaq: SOLR) and Chinese insurance broker CNinsure (Nasdaq: CISG) reporting their quarterly financials. Both companies are expected to post modest growth for the period.

(NYSE: AZO) gets in the zone on Tuesday. The auto-parts retailer appears to be an all-weather company. It coasted through the recession, delivering strong sales as cash-strapped drivers maintained their older cars. New-car sales have bounced back, and AutoZone is still growing.

You won't need a warehouse-club membership card to check out Costco's (Nasdaq: COST) earnings come Wednesday. The popular provider of groceries and other wares in bulk sizes is expected to earn $0.77 a share in its latest quarter, comfortably ahead of the $0.66 it delivered a year earlier.

Another company on the earnings block for Wednesday is NetApp (Nasdaq: NTAP). The enterprise data-storage company isn't growing its bottom line as quickly as Costco this quarter, although going from $0.50 a share last year to $0.53 this time around is at least a small step in the right direction.

There are a few high-end jewelers reporting earnings this week. Tiffany (NYSE: TIF) is the best known, and it reports what should be improved results on Thursday. If folks are spending money on expensive bling again, the economy can't be doing too badly.

The trading week closes out with Mentor Graphics (Nasdaq: MENT) sharing its financials heading into the long holiday weekend. Mentor's targeted net income of $0.18 a share would reverse a small year-ago deficit.

Until next week, I remain,
