U.S. stock futures wavered Monday as investors geared up for corporate earnings season to kick off this week. Futures tied to the S&P 500 slipped 0.3% after the broad-market index reached a record high on Friday. Futures linked to the Nasdaq-100 ticked up 0.1%, suggesting further gains in technology stocks after the Nasdaq Composite ended last week at a record. Dow Jones Industrial Average futures edged down 0.5%. In premarket trading, Virgin Galactic jumped over 7% after the company launched founder Richard Branson to the edge of space over the weekend. He returned to Earth safely on Sunday. The shares have doubled so far this year. Chinese ride-hailing company Didi Global slumped nearly 5% premarket. Beijing’s moves to crack down on data policy and on overseas IPOs have battered the recently listed company’s shares. Earnings season begins Tuesday and investors will be closely watching to see if companies’ results justify the high valuations in the equity market.
