Tesla Motors rose 1.3% in premarket trading.

Tesla sold 21,900 electric vehicles in the first week of December in China, marking the company’s highest weekly sales in the fourth quarter of this year, according to Tesla China.

In November, Tesla set a record by selling over 73,000 units in China.

The Tesla Model Y topped the list as the best-selling passenger vehicle with 556,000 units sold last year.

To compete with rising market competition, Tesla introduced a limited-time discount on the Model Y. Buyers can receive a 10,000 yuan (around US$1,379) discount on outstanding loans.

GameStop sales fell from a year ago in the company's latest quarter, coming in below Wall Street estimates, but the videogame retailer also swung to an unexpected profit.

U.S.-listed shares of the company rose 4% in premarket trading, likely due to the surprise profit. The company reported net income of $17.4 million for the quarter, compared with a net loss of $3.1 million in the same period last year.

GameStop reported third-quarter adjusted earnings of 6 cents a share on net sales of $860.3 million. Analysts surveyed by FactSet expected the company to post a loss of 3 cents a share on revenue of $888 million.

Sales in the latest quarter were down 20% from the year-earlier period, when GameStop reported revenue of $1.08 billion.

GameStop, in its usual fashion, didn't schedule a news conference or a call with analysts and investors to discuss the results.

GameStop also said that during the quarter, it completed a previously disclosed "at-the-market" equity offering program by selling 20 million shares of its common stock. However, GameStop added that it doesn't anticipate any more offerings involving its stock during the current fiscal year.
