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

On this episode of Stock Movers:
- Stellantis will take roughly €22 billion ($26 billion) in charges linked to a sweeping overhaul of its operations as high costs and muted electric-vehicle sales force the automaker to adjust its strategy. Stellantis shares fell as much as 14% in Milan, with the announced charges exceeding analyst projections.
-Societe Generale's stock declined after it reported fourth-quarter results for its trading units that missed estimates. Revenue from buying and selling fixed income securities and currencies fell 13% in the period from a year earlier, while equities trading fell 5.3%, it said in a statement on Friday. Analysts had anticipated growth for both units. Shares in the lender dropped as much 3.9% in early Paris trading. 
- Banco Sabadell Chief Executive Officer César González-Bueno is leaving in a surprise move just a few months after he led the lender’s successful defense against a hostile bid from rival BBVA. Shares in Sabadell dropped as much as 6.5% in early Madrid trading.
