Meta Platforms Inc. changed its narrative in a big way this week, and that’s resonating on Wall Street. Three months ago, Chief Executive Mark Zuckerberg and his leadership team sounded fairly defiant as they laid out big spending plans despite economic angst, an attitude that helped send shares toward one of their worst days on record. Shares of Facebook’s parent company closed up 23.3% in Thursday trading to stage their second-largest one-day percentage rally on record, and their best performance since July 25, 2013, according to Dow Jones Market Data.
