LIVE: Facebook's Q3 Earnings

The full results will appear here.

Analysts are expecting:

• Earnings per share: 19 cents
• Revenues: $1.91 billion

Facebook stock has been trading around $49 all day, down from a recent high of $54.22 but up 50% since July. Some analysts have price targets of $65 for Facebook.

ComScore says mobile visits to Facebook grew in the quarter. Mobile users, and mobile revenue, are the key drivers of Facebook revenue over all.

Other issues we'll be watching and listening for:

• Instagram: The company just launched ads on the photo sharing platform. Will it affect revenue guidance?
• Video ads: Facebook keeps delaying the launch of these auto-play spots that are reportedly coming with a hefty price tag in the millions.
• Mobile app install ads: Facebook has made a big deal of the success of these ad units which urge people to download stuff onto their phones. Will we get new numbers?
• Forrester: The research group put out a much-criticized report this week. We'll see if CEO Mark Zuckerberg or COO Sheryl Sandberg feel stung enough by it to make some anti-Forrester zingers.
