US stock futures fell Thursday as trading resumed after the Christmas holiday, as Wall Street looked ahead to one of the only economic data points of the week.

Futures tied to the S&P 500 (ES=F) were up 0.3%, and those on the tech-heavy Nasdaq (NQ=F) also declined 0.3%. Dow Jones Industrial Average futures (YM=F) lost 0.4%, leading the way down.

Meanwhile, bitcoin (BTC-USD) slumped, falling below the $96,000 level as volatile trading continued. Crypto-linked stocks like MicroStrategy (MSTR) tracked the declines.

Markets looked to be struggling in a bid to extend the start of the “Santa Claus rally,” which kicked off with a bang on Tuesday. All three major indexes rose around 1%. The S&P 500 (^GSPC) and Nasdaq Composite (^IXIC) are within striking distance of their records after clawing back gains from a Fed-fueled dive last week.

As Wall Street saunters back from its holiday break, the normally routine release on weekly jobless claims will grab more of the spotlight than usual, as it is the only piece of the jobs puzzle on the docket this week.
