Vistra shares have rallied sharply over the past week, up 15.3% over five days to $161.48, with the move tied to a conditional Energy Department loan for its nuclear fleet. The stock remains 23.0% below its 52-week high of $217.10, though it trades 11.8% above its 20-day moving average with an RSI of 69 approaching overbought territory.
