How Corporate America Has Changed After the Capitol Attack

Flight cancellations surpass 1,000 for an 11th straight day. Nearly 1,700 flights were canceled yesterday, bringing the total since Christmas Eve to over 22,000. Labor shortages, in part because of coronavirus cases, were to blame.

WarnerMedia declares its pandemic streaming strategy a success. HBO and the HBO Max platform ended 2021 with nearly 74 million subscribers, surpassing expectations. WarnerMedia’s chief, Jason Kilar, said the news validated his decision to put his studio’s movies on HBO Max the same day they hit theaters, a move that angered Hollywood.

A notable short-seller is taking on Tesla. Fraser Perring, who identified fraud at Wirecard years before the German payments company collapsed, said he is betting that Tesla’s highflying stock price will crash. “I’m short again,” Perring tweeted. Tesla’s stock fell 5 percent yesterday, though its market cap remains above $1 trillion.

A Fed official’s stock trading disclosures raise questions. Richard Clarida, the central bank’s departing vice chair, previously came under fire for buying shares in a fund in early 2020, a day before the Fed announced potential pandemic support measures. The Fed initially described Mr. Clarida’s purchase as a routine, planned move. But a newly amended disclosure shows that he had sold that same fund a few days before.

Djokovic’s latest court battle

After being detained at a Melbourne airport, the Serbian tennis star Novak Djokovic was denied entry to Australia amid suspicions about his medical exemption from getting the coronavirus vaccine. The move throws into doubt his entry to the Australian Open — and raises thornier questions about vaccine mandates.

“Rules are rules,” Scott Morrison, Australia’s prime minister, tweeted of the move. It capped a whirlwind of developments: Djokovic, who had kept his vaccination status under wraps for months, was granted a last-minute exemption to Australian rules requiring visitors be vaccinated or stay in quarantine for 14 days, allowing him to attend the Open. (Tournament officials said medical experts involved in the exemption didn’t know his identity, and a “handful” of exemptions for other players were granted.)
