eBayled tech stocks higher Monday after Smith Barney raised its rating on the online auction king to "buy" from "hold."

Analyst Mark Mahaney said eBay's recent strong results appear sustainable, and he added that a significant obstacle was removed when Googleconfirmed that it is not working on a competitor to PayPal.

Fee increases, improved buyer protection and higher average selling prices are all benefiting eBay, Mahaney wrote.

"Based on channel checks, our proprietary listing database and incremental analysis, we believe the June quarter results are sustainable," he wrote.
