Vistra's roughly 5.5% move added about $3 billion in market value in a single session.

The stock climbed off the open and held those gains, a sign of sustained buying pressure.

Vistra sits in the independent power producer group, a corner of the market where large single-session moves tend to draw attention across the sector. When a name of this size moves this much, it becomes a reference point for how the broader group is trading.

Keep an eye on the stock into the close: finishing near session highs would confirm the move's strength.
