Confluent, Inc. (CFLT) gained 0.64% after IBM announced plans to acquire the data streaming platform for $31 per share. The acquisition news prompted multiple analysts to raise their price targets, signaling confidence in the deal's value.

Rocket Lab Corporation (RKLB) rocketed higher by 22.78% as the aerospace company advanced a South Korean Earth-imaging mission into its next available launch window. Investors continue to see Rocket Lab as a serious player in the commercial space race.

Warner Bros. Discovery, Inc. (WBD) climbed 8.65% as the entertainment industry heated up with a bidding war between Paramount and Netflix. The competitive dynamics in streaming content appear to be working in Warner Bros.' favor.

Mining and Manufacturing Round Out the List

Pan American Silver Corp. (PAAS) increased 11.18% as precious metals companies traded higher across the board. The strength in commodities appears driven by investor optimism around a potential Federal Reserve rate cut, which typically benefits hard assets like gold and silver.

Hecla Mining Company (HL) rose 15.86% during the week, riding the same precious metals wave that lifted Pan American Silver.
