Stock futures were sliding on Monday, as investors looked set to begin December in a risk-off mood.

These stocks were poised to make moves:

New Fortress Energy jumped 32% ahead of the opening bell. Regulators in Puerto Rico said late Friday that they had tentatively approved a contract with the embattled liquefied natural gas supplier, which has faced questions about its ballooning debt. The deal may give the stock, down 92% this year, a much-needed boost.

Coupang slumped 8.9% in premarket trading after a massive data leak at the South Korean retailer, which is listed on the New York Stock Exchange. South Korean police said they were investigating the hack, which exposed about 34 million accounts.

Crypto stocks were sliding following another selloff in Bitcoin, which has dropped more than 5% over the past 24 hours to fall back below $90,000 to around $87,000. Shares in the crypto exchange Coinbase Global dropped 3.7%, while Bitcoin investor Strategy fell 4% and online-trading platform Robinhood Markets was down 3.3%.

Precious metal miner Newmont climbed 1% as gold futures rose and silver hit a record high of $58.61 an ounce. Silver prices have surged 98% this year, thanks to booming industrial demand and a trickle-down of safe-haven money away from gold.

Chip designer Nvidia, iPhone maker Apple, and Google owner Alphabet were down 1.2%, 0.6%, and 0.9% respectively ahead of the opening bell, as investors opted to start the month by ditching tech stocks. Apple and Alphabet both threatened to snatch Nvidia's crown as the largest U.S. company by total market capitalization last week, amid questions over whether Nvidia's graphics processing units can maintain their dominant market share.

Software developer MongoDB and provider of high-speed connectivity solutions for data centers Credo Technology are both expected to post earnings after Monday's closing bell.
