Expected impact

potential downside pressure as investors reassess the valuation premium

Evidence & confidence

Market effects

Energy stocks may see short‑term rally but valuation concerns could limit broader sector upside.

Tightening oil supplies and near‑$100 crude prices could lift global energy equities, though overvaluation risks remain.
