Volvo shares jumped over 20% after it announced plans to stop funding subsidiary Polestar Automotive. Volvo may hand stewardship of Polestar to majority shareholder Geely Holding, which owns 78.65% of Volvo. Volvo's CFO said this allows both companies to fully focus on growth as Polestar moves to a new trajectory. Volvo Cars announced a significant increase in fourth-quarter operating income to $639 million, surpassing expectations and showing growth from $372 million in the same period the previous year.
