The stock recovered, but plunged more than 20% in response to Facebook announcing quarterly revenue that fell short of Wall Street estimates. Facebook warned investors its top-line growth rates would decline by "high single-digit" percentages in the coming quarter as it ramped up its self-declared war on safety and security. Shares are down 34% from their record high set on July 25.
The data scandal and brutal earnings prompted Wall Street to sound the alarm the stock. Facebook is "not as in control of its business as it needs to be," Brian Wieser, a long-time Facebook bear at Pivotal Research Group said in October.
But Sanderson said that Wall Street may have ignored one key fact - Facebook' users are still sticking to the platform.
"Users may be spending less time, but Facebook is still firmly entrenched as a daily habit," Sanderson said. "We expect the substantial majority (nearly all) users will opt-in to sharing of personal data, usage and other data in exchange for better services, so long as they are free of charge."
By Sanderson's calculation, Facebook's daily US users equate to about one-ninth of the five largest US television networks. "Facebook is unique in its scale and reach, like television that continued to grow long past its peak in audience," he said, adding that Facebook's video-enriched Stories and Watch features have potential to reaccelerate engagement growth across the Facebook community.
Sanderson added that US regulators won't be too harsh on Facebook and other US tech companies for fear of hurting innovation.
"Global competitiveness will be a consideration for regulators and point to the pace of innovation on Chinese platforms that leverage troves of consumer data to create highly innovative and valuable services," he said.
Sanderson has a "buy" rating and $190 price target - 30% above where shares were trading Monday.
