Shutterfly leads the way as e-commerce stocks advance nearly 1% for the week

In a flat week on Wall Street, the Internet Retailer Online Retail Index advanced 0.78%.

That put it well ahead of the broader stock market, as the Dow Jones Industrial Average slipped 0.13% last week and the Standard & Poor’s 500 Index inched up 0.02%.

Leading the way among the e-commerce index stocks was online retailer Shutterfly, whose shares surged after it reported a third quarter sales gain of more than 20%. But investors were far less impressed with Overstock’s Q3 report, driving down the off-price e-retailer’s shares more than 16% for the week.

Here are the best-performing stocks last week in the Online Retail Index and the gain in stock price for each:

• Shutterfly, 17.5%

• VistaPrint, 9.2%

• Akamai, 8.5%

•United Online, 7.9%

• 1800Flowers.com, 6.5%
