Good morning. New Year attacks in New Orleans and Las Vegas raise security fears. One man dominates Wall Street’s 2025 predictions. And how to make your resolution to get more sleep actually stick. Listen to the day’s top stories.

Authorities are investigating whether there’s any connection between yesterday’s truck attack on revelers celebrating New Year’s in New Orleans and the deadly explosion of a Tesla Cybertruck outside of President-elect Donald Trump’s hotel in Las Vegas. The suspect in the New Orleans assault—which killed at least 15 people—previously served in the US Army and may not have acted alone, according to the FBI. An ISIS flag and improvised explosive devices were found in his vehicle. The College Football Playoff quarterfinal at the Sugar Bowl between Georgia and Notre Dame was postponed a day.

The Las Vegas explosion injured seven people and killed the driver, who has not been publicly identified. Elon Musk said Tesla had confirmed the explosion was caused by “very large fireworks and/or a bomb” carried in a rented Cybertruck.

Dockworker union leaders and employers are set to resume contract talks on Jan. 7 as the threat of another strike looms, a person familiar said. New negotiations will be a relief for importers and exporters. The world’s No. 2 container carrier, Maersk, had already warned customers to remove cargo from East and Gulf Coast ports before a Jan. 15 deadline. Here’s what’s at stake.

All eyes are on Tesla’s sales numbers due today. Wall Street isn’t sure the carmaker can avoid its first annual sales decline in over a decade. Chinese rival BYD said it sold a monthly record of 509,440 plug-in hybrid and pure-electric passenger vehicles in December, taking its annual EV tally to 1.76 million. The rise in total sales puts it near to beating Ford and Honda for the year.

Chinese hopes for a brighter 2025 started badly as stocks posted their worst start to a year in nearly a decade. Weaker-than-expected manufacturing data and concern about Trump imposing more tariffs did the damage. US stocks looked poised for a more optimistic open as tech companies led futures higher.

The Big Take

Opinion

Buckle up. This year will be a rollercoaster for investors, Marcus Ashworth and Mark Gilbert write. The interplay of politics, economics and markets will make assaying the paths of stocks, bonds, commodities and currencies even harder than usual.
