Market Movers — June 13, 2026

The 100 most actively traded US stocks on June 13, 2026, ranked by volume — 56 up, 44 down. Here are the day's biggest moves and the headlines driving them.

The market take

Roku's 20% surge stands as the lone breakout winner today, though the headline lacks specifics—suggesting investor optimism around streaming or advertising trends unmoored from broader market sentiment. Meanwhile, space stocks are in visible retreat despite what should be a tailwind from SpaceX's moment in the spotlight. Firefly, AST SpaceMobile, Intuitive Machines, Redwire, Rocket Lab, and Planet Labs all retreated sharply, with headlines pointing to a sector rotation away from smaller space players after SpaceX's debut stole momentum. Intuitive Machines faced an additional headwind missing a NASA rover contract, though moon base ambitions remain intact.

The AI chip sector offered a separate lift: Arm and POET both rallied solidly as semiconductor names benefited from renewed AI enthusiasm. Meanwhile, EchoStar stumbled on dual pressures—SpaceX-linked competition concerns combined with debt payment risks tied to DISH. Breadth remained modestly positive at 56 up versus 44 down among the top 100 most active names, but the day reveals clear thematic bifurcation: established AI beneficiaries and high-momentum retail plays gained ground, while speculative space ventures and satellite operators faced indiscriminate selling.
