US STOCKS-Tesla, Twitter among premarket's biggest movers

By Ryan Vlastelica

NEW YORK, Oct 2 (Reuters) - Tesla Motors Inc (Xetra: A1CX3T - news) was one of the biggest movers of Thursday's premarket session, after the company's chief executive hinted at a new product that would be unveiled next week.

Elon Musk, CEO of the electric car company, wrote on Twitter that it was "about time to unveil the D and something else." An image that accompanied the tweet suggested the unveiling might include a new vehicle model.

Shares (Berlin: DI6.BE - news) were up 3 percent to $247.50 before the bell. The stock has rallied about 60 percent in the year to date, building on last year's surge of more than 340 percent.

Twitter Inc (Xetra: A1W6XZ - news) also advanced in the premarket session, up 2.4 percent to $51.28 after JPMorgan upgraded the social network to "overweight" from "neutral" and raised its price target on the stock by $10 to $64.

"Twitter is a primary beneficiary of the shift toward mobile advertising ... and we are increasingly confident in the company's ability to grow users over time," the firm wrote in a note to clients.
