Citi Examines Utility Stock Volatility Ahead of Q3 End
Citi conducted an analysis of 30‑day implied volatility across a basket of 30 utility‑sector equities as the third quarter of 2026 draws to a close. The assessment identified a range of volatility levels, with several stocks displaying notably elevated implied volatility.
The utilities with the highest implied volatility were PG&E Corp (NYSE:PCG), NRG Energy (NYSE:NRG), Constellation Energy (NASDAQ:CEG), Edison International (NYSE:EIX) and Ormat Technologies (NYSE:ORA). California‑based utilities exhibited heightened volatility, which Citi attributes to recent legislative outcomes affecting the state’s power sector. Independent power producers, in contrast, are contending with uncertainty surrounding datacenter‑related policy and the sustainability of their business models. Ormat Technologies also disclosed that it will host an analyst day in the near term.
Over the preceding two‑week window, NRG Energy was the sole company in the cohort to record an increase in implied volatility, rising by 2.88 %. Evergy (NYSE:EVRG) showed no change, while the majority of the remaining utilities experienced a decline in implied volatility. The most pronounced two‑week reductions were observed in stocks that began the period with the highest volatility levels, led by NET Power followed by Sempra Energy (NYSE:SRE).
Consolidated Edison (NYSE:ED) posted the lowest implied volatility reading within the sample, with a modest increase of 0.75 % over the measurement horizon. Other utilities positioned near the bottom of the volatility spectrum included Atmos Energy (NYSE:ATO) at –0.34 %, Evergy at –0.95 %, Duke Energy (NYSE:DUK) at –0.49 %, WEC Energy Group (NYSE:WEC) at –0.06 %, Southern Company (NYSE:SO) at –0.90 % and CMS Energy (NYSE:CMS) at –0.20 %.
