Market Prism's verdict on COST

Market Prism classifies COST as Overvalued Stable — the price sits above what the narrative justifies, but the story isn't actively breaking down. Narrative energy is moderating at 53%, an early sign of fatigue.

Valuation outlook for COST

Overvalued-but-stable names can hold a premium for a while. The risk is asymmetric: limited upside, with a long way to fall if the story cracks. The 40.1% fair-value deviation is extreme and, historically, tends to revert within 30–60 trading days.
