The Nasdaq 100, a tech-heavy index, finished last week up 0.42% to close at 1,932.43. Investors appeared noncommittal amid uncertainty over the economic consequences of a contentious health-care bill that yesterday passed in a close vote in the U.S. House of Representatives.

A weekly tour of tech
The week's top stock, Cintas, a Motley Fool Inside Value pick and a supplier of corporate uniforms and related equipment, last week reported slightly better-than-expected earnings last week.

But the news is actually better than that. Revenue declined 5.1% during the company's fiscal third quarter, a vast improvement over the 10.2% decline Cintas suffered in Q2. Meanwhile, the balance sheet has improved nicely thanks to healthy free cash flow -- more than $350 million worth over the past nine months.

Contract manufacturer Flextronics -- a potential millionaire-maker penny stock a year ago -- rallied without reporting any major news, but it's up again today, maybe on hopes that a broad recovery in goods manufacturing bodes well for the business.

The New York Federal Reserve's manufacturing survey showed the new order index jumped 10.5 points in the region, rising to the index's highest level since October of last year, RTT News reports. Good news like this is bound to move the depressed shares of Flextronics, which traded for just more than 15 times this fiscal year's projected earnings as of this writing.

Finally, the week's top loser, SanDisk, wasn't much of an offender. If anything, the lack of news explaining the week's downturn suggests that investors decided to take some profits after seeing shares of the flash memory maker hit new highs the week prior.
