Despite the disappointing second-quarter report, Citigroup remains positive on Google.

"Google's underlying fundamentals are intrinsically strong," analyst Mark Mahaney wrote. "We'd be buyers on this pullback."

Mr. Mahaney noted that operating margin came in "modestly light" but that Google showed strength in revenue from its partner sites and licensing.
