On this episode of Stock Movers, we take a look at some of the week's biggest gainers and decliners:

- Meta Platforms' (META) plans to manufacture its in-house AI chip made companies like Applied Materials, Lam Research, and KLA Corp. happy. The AI infrastructure companies' stocks rose, with Lumentum rising 12% and KLA and Lam Research advancing 4.5% and 6.3%, respectively. Meta's decision to move forward with its in-house chip could be a boon for Applied Materials, Lam Research, and KLA, which make wafer fab equipment that turns raw silicon wafers into microchips.

- Paramount Skydance Media (PSKY) shares are trending after a report that U.S. states could sue to block the company’s $110 billion acquisition of Warner Bros. Discovery. States concerned about the deal’s competitive impact could file suit as soon as next week, according to sources familiar with the matter.

- Forte Biosciences shares surge as much as 47%, most intraday since May 2025, after the biotech company said its experimental molecule FB102 showed a statistically significant benefit in vitiligo observed by week 24 after completion of 12-week treatment period.
