Today's biggest winners and losers in the stock market.

On this episode of Stock Movers:
- Shell Plc said its fourth-quarter profit slumped, undershooting expectations as lower crude prices, a weak oil-trading performance and a struggling chemicals business dented earnings.
- Volvo Car shares plunged the most on record after the Swedish-origin automaker closed out last year with worse-than-expected earnings.
- A.P. Moller-Maersk plans to cut jobs and focus on cost discipline this year as the container giant seeks to insulate its earnings against deteriorating freight rates with Red Sea routes reopening. The shares fell.
