US: Tesla tumbles as stocks end mostly lower

[NEW YORK] Tesla shares tumbled Thursday following a report the company faces intensifying scrutiny from securities regulators as US stocks finished a quiet session mostly lower.

The Dow Jones Industrial Average dropped 0.3 per cent to 25,509.23.

The broad-based S&P 500 slipped 0.1 per cent to 2,853.58, while the tech-rich Nasdaq Composite Index added less than 0.1 per cent to 7,891.78.

Tesla Motors fell 4.8 per cent after Bloomberg News reported that US Securities and Exchange Commission enforcement attorneys in San Francisco were probing the electric car maker after chief executive Elon Musk said on Twitter Tuesday he was considering taking the company private.

The SEC, which had already been gathering information on Tesla's public pronouncements, added questioning of whether Musk's claim that he had secured funding for a takeover to the inquiry was meant to be factual, Bloomberg said, citing people familiar with the matter.

Analysts described broader market activity as low-key following US inflation data that was seen as benign in terms of allowing the Federal Reserve to maintain a gradual pace of interest rate hikes.

"It's been a very quiet day," said Quincy Krosby, chief market strategist at Prudential Financial. "Earnings have been very strong and the guidance has been positive but it's not new."

Drugstore chain Rite Aid dived 11.8 per cent after announcing it had called off a merger with Albertsons.

Booking Holdings slumped five per cent on disappointment over the company's third-quarter forecast.
