NEW YORK (TheStreet) – Facebook (FB) - Get Report continues to post gains two days into its announcement it would offer a payment service for its Messenger app, rising 4.3% during this time. Tesla Motors (TSLA) - Get Report, meanwhile, tanked despite announcing its product enhancement update. AT&T (T) - Get Report also edged down as the telecommunications giant faced a multi-million fine.

Facebook rose 2.3% to close at $82.75. That gain adds to the stock's ascent since it closed at $79.36 on Tuesday following its Messenger app payment service announcement. 

The new service helped spur Facebook's shares to a new record high of $83, and a Benzinga report pointed to favorable comments from analysts at J.P. Morgan and Nomura as a potential catalyst.

Tesla Motors fell 2.5% to end the session at $195.65.

The high-end electric vehicle maker stumbled despite announcing it would soon offer upgrades to its Model S sedan, such as a hands-free driving capability. It also unveiled a Range Assurance feature that will alert drivers of its Model S when they are approaching the limit of their battery power, according to a Reuters report.

Tesla's shares also fell despite a positive report from RW Baird, which noted the analysts' recent meetings with Tesla's management made them more comfortable that the company will hit its delivery target, as well as its introduction of its Model X in the third quarter.

AT&T slipped 1.2% to end the day at $33.20.

The telecommunications giant got hit with a $40 million fine after failing to read a court document that a judge denied its request to overturn a jury verdict in its patent-infringement case with Two-Way Media, according to a Bloombergreport.

As a result, AT&T missed its 30-day deadline to appeal the jury verdict, which awarded Two-Way Media $27.5 million, plus interest, over AT&T's use of its tracking technology that reveals what users are watching on streaming video services, according to the Bloomberg report.
