Price chart — 52 weeks
OakBag could not build a reliable fair-value estimate for National Grid Plc (NGG) — none of its valuation methods cleared the model's safety checks (typically a company running an operating loss, where a discount can't be trusted). At a recent price of $83.99 the traffic light is set so it looks fairly valued, benchmarked against other Utilities names. This is a model output for research, not a price target or a recommendation.
