On today's podcast:

1) Tesla Inc. shares plunged after Elon Musk’s pitch to look past slower sales growth fell flat with investors. The stock fell 8% in early trading Thursday, after Tesla narrowly missed earnings estimates and warned its rate of expansion will be “notably lower” this year. The company spent all of 2023 cutting prices to boost sales, which ate into profits.

2) Boeing Co. faces a commercial setback after the US Federal Aviation Administration froze planned production increases for its 737 Max aircraft, a move that interrupts the planemaker’s growth ambitions at a time of surging demand and intensifying competition with Airbus SE.

3) Two days after his decisive victory in the New Hampshire primary, Donald Trump is set to take the witness stand in New York to rebut defamation claims by writer E. Jean Carroll — testing his ability to sway a federal jury and a judge he’s already clashed with.
