Investing.com -- Tesla’s fourth-quarter update offered stronger margins and cash generation, but Jefferies said the real story was an earnings call that ranked as the company’s “most interesting” in many quarters, driven by sweeping investment plans and major strategic pivots. Jefferies analyst Houchois highlighted that Tesla delivered a “healthy beat on core auto margin and cash,” with group gross profit of $5 billion and a 20.1% margin, far above consensus. Free cash flow came in at $1.42 billion, with Tesla’s cash pile growing to $44.1 billion.
