E-commerce stocks advance for the week, though some earnings reports fall flat

The stock market rebounded last week, and e-commerce stocks were right in the middle of the action.

The Internet Retailer Online Retail Index, which tracks the stocks of 25 online retailers and e-commerce technology providers, moved up 3.61% last week, right in line with the broader market. The Dow Jones Industrial Average advanced 3.58% and the Standard & Poor’s 500 Index moved up 3.78%.

Several e-commerce companies reported earnings last week, and they got mixed reviews on Wall Street. Among the reporting companies whose shares advanced were Akamai Technologies, whose content delivery network accelerates web sites, and online retailer 1800Flowers.com. E-retailers Shutterfly, Overstock and Amazon all moved lower after reporting quarterly results. Amazon lost 7.4% of its share value over profit worries, despite reporting a 44% increase in sales.

And Netflix absorbed another pummeling after disclosing that it had lost 800,000 U.S. subscribers last quarter following a botched effort to raise prices.
