On this episode of Stock Movers:

- Airbnb (ABNB) shares fell after a New York Times article said that the Spanish government ordered the company to remove almost 66,000 listings from its platform. The move widens a “crackdown on tourist rentals as it seeks to alleviate a housing crisis that has become among the worst in Europe,” the New York Times said. Airbnb said in a statement that it would continue to appeal all decisions linked to the case, according to the article; a company spokesperson said the listings would be kept up until the appeal made its way through the courts

- Moderna (MRNA) stock rose on news that US regulators will no longer approve Covid booster shots for healthy adults and children without new studies. The new rule adds a costly requirement for drugmakers, though boosters will still be available for millions of high-risk Americans. Food and Drug Administration Commissioner Marty Makary and Vinay Prasad, who leads the agency’s vaccine division, outlined the approach they intend to take with updated versions of the immunizations in an article published Tuesday in the New England Journal of Medicine. The agency’s willingness to continue making the shots available for high-risk people with a wide range of health conditions was a relief to the industry, which feared a wave of restrictions from President Donald Trump’s political appointees who questioned the vaccines. Investors were buoyed as the new policy doesn’t require the costly trials for older adults who are more likely to get vaccinated.

- Amer Sports (AS) shares hit a record high as the maker of Wilson tennis rackets and Salomon ski boots boosted its adjusted profit forecast for the full year and reported first-quarter results that topped expectations.
