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

On this episode of Stock Movers:

- Meta Platforms (META) and Google Parent Alphabet (GOOG) shares were down today as investors see a long-term overhang related to verdicts in a social media addiction trial. Yesterday, a jury found Meta and Google liable for a 20-year-old woman's mental health struggles, which she said were caused by her addiction to social media, and ordered them to pay damages.

- Shares of haircare brand Olaplex Holdings (OLPX) surged after German consumer brand Henkel announced that it has agreed to buy the company.

- As travelers across the US endure hours-long security lines at airports due to the partial government shutdown, investors are piling into car-rental companies on bets the disruption will push more people onto the road. Hertz Global Holdings Inc. (HTZ) shares rose about 9.2% on Thursday, while Avis Budget Group Inc. (CAR) surged 13% for its biggest one-day gain since June, as chaos at US airports drove optimism that more travelers would rent cars instead. Traffic to Hertz’s website jumped about 15% this week as customers looked for ways around air-travel disruptions. The company has been promoting discounts on last-minute reservations and one-way rentals.
