NEW YORK, Jan 20, 2026, 12:29 EST — Regular session.

• Vistra shares fell about 3.9% to $160.12 in midday trade.
• Power names slid broadly as Wall Street sold off and volatility picked up.
• Traders are watching Vistra’s Jan. 22 debt deal closing and the next policy headlines tied to power prices and data-center demand.

Shares of Vistra Corp fell 3.9% to $160.12 in midday trading on Tuesday, extending a choppy stretch for a stock that has become a proxy for the U.S. power-demand trade.

The slide matters because investors have been leaning into generators tied to the data-center buildout, and Vistra sits near the center of that story. When risk appetite fades, the group can move fast.

That backdrop got uglier…
