The call for an audit of Facebook’s metrics comes a week after the social network acknowledged inflating its video metrics.
The Internet Retailer Online Retail Index fell nearly 6% for the week.
Investors bid up the stocks of No. 1 online retailer Amazon.com Inc. and web and mobile measurement vendor Keynote Systems Inc. last week after the two companies reported earnings. But otherwise Wall Street savaged e-commerce shares, dropping the Internet Retailer Online Retail Index 5.80% for the week, its worst showing of 2011.
The broader market was also down last week, although not as sharply. The Dow Jones Industrial Average lost 3.48% for the week and the Standard & Poor’s 500 Index declined 3.30%.
Only five Online Retail Index stocks advanced last week as 20 lost ground. The index tracks the stocks of 25 online retailers and e-commerce technology and service providers.
The biggest winner was Keynote, which last week reported a 25% year-over-year revenue increase, after adjusting for accounting policy changes. Also moving up for the week was Amazon, which reported another blockbuster quarter, with revenue 51% higher than the same quarter last year.
Online printing services retailer VistaPrint Ltd. took the biggest hit of the week, losing more than 40% of its value after management projected lower-than-expected earnings for the rest of the year. E-retailers Overstock.com Inc. and Shutterfly Inc. also suffered double-digit losses after reporting second quarter results last week.
