COST (COST)

Secondary decision view: valuation · portfolio context · the data you need before acting on a single-source signal.
Neutral

COST is rated NEUTRAL as it trades far above all estimated floors with expensive PE and PB percentiles, yet carries no red alerts and has high floor confidence.

  • Current PE of $53.15 sits at the 87th percentile, flagged as expensive, and the stock trades 381.5% above the buyzone floor, indicating extreme premium pricing.
  • Despite the premium, all three computed floors (dividend, valuation, EPV) are valid and carry high confidence, with a 4.8% discount to the combined floor suggesting some downside cushion.
  • No risk alerts are present (0 alerts), and implied volatility rank is at its 1-year high (100%), signaling elevated option pricing but no fundamental distress.
Verdict bucket from deterministic rule (validation / floor distance / risk alerts). LLM narration only — never picks the bucket.

AI Synthesis
根据分析师评论,Costco远期市盈率达44.8倍,处于87%分位,估值偏高。尽管0.98的PEG指数和46%的盈利增长部分支撑此高估值,但市场已充分计入增长预期,业绩稍有不及便可能面临估值大幅下调风险。在此背景下,本次估值采用“回撤基准法”。通过ATH(历史峰值)回撤50%的公式计算,得出其估值底部(floor price)为$520.12。根据ATH回撤35%(即ATH的65%),得出黄金买入区域的参考价(golden price)为$676.15。本次估值的置信度为低。

Glossary (click to expand)
Forward P/E
P/E using analysts' next-12-month EPS estimates. More forward-looking than trailing P/E, but exposed to forecast error.
Trailing P/E
P/E using actual EPS from the last 12 months. Distorted by one-time events (asset sales, impairments) until they roll out of the window.
P/B (Price-to-Book)
Stock price / book value per share. Meaningful for asset-driven sectors (banks, insurers); high values are normal for asset-light sectors (tech, consumer).
PEG
P/E ÷ earnings growth rate — \"how much P/E you pay per 1% of growth\". <1 = cheap-ish, >2 = priced-in.
Regime-mismatch drawdown model
When P/E distribution undergoes a structural shift (business transformation, sector re-rating), traditional \"revert to historical P/E percentile\" misleads. This model uses historical max drawdown × current EPS instead.
EPV (Earnings Power Value)
Greenwald framework: assume zero growth + current earning power is sustainable. Yields a conservative lower bound (asset + franchise value).
Heuristic Fallback
Backup estimator used when the primary method (P/E percentile, yield reversion, etc.) is unreliable due to data issues. **Lower confidence** — reference only, not auto-execute.
Confidence
Primary method applicable → high; multiple methods agree → medium; single heuristic fallback → low. Low confidence means review before acting.

Is COST (COST) overvalued right now?

COST (COST) is currently trading at a trailing P/E of 53.1, sitting at the 87th percentile of its 5-year valuation history. A high percentile suggests the market is pricing the stock above its own historical norm — useful context before sizing a new position or selling premium against it.

COST (COST) — what's the SELL PUT risk profile?

Selling cash-secured puts on COST (COST) is a common income strategy, but the right strike depends on your floor price (the level you'd happily own at) and the option chain's buffer/APY tradeoff. The full ladder view (deferred to a future release) ranks candidates by buffer percentage first, then APY — see the option ladder methodology for why buffer matters more than yield in this strategy.

COST (COST) — which option strategy fits your view?

If you're bullish long-term but cautious near-term on COST (COST), SELL PUT into your floor zone collects premium while waiting for a better entry. If you already own it and are neutral-to-mildly-bullish, COVERED CALL caps upside but harvests time decay. The wrong strategy on the right ticker still loses money — match the trade to your view, not the other way around.

COST (COST) — is now a good entry?

Entry timing on COST (COST) is a function of your floor price (hard buy zone) and golden price (back-the-truck-up zone). Both are personal — set them in your watchlist and we'll alert you when the market hits either level.

FAQ

Why does COST show different P/E numbers on different sites?

Different data providers use different earnings windows (TTM vs forward, GAAP vs adjusted) and update at different cadences. We surface trailing P/E with a 5-year percentile rank to give context — a P/E of 30 is hot for one stock and cold for another.

Does this page show COST's implied volatility?

Not on this v0 page — the dedicated volatility tool covers IV with multi-source voting (IBKR + Polygon + yfinance). For pure IV lookup, use /tools/volatility. This page is for decision-stage queries that pull together valuation + portfolio context.

How is this different from Yahoo Finance or 雪球's COST page?

Those sites are great for raw data discovery — last price, news, headline P/E. This page is built for the second look: you've already seen a single-dimension signal somewhere else, now you need multi-dimensional decision context (your floor, the valuation percentile, your portfolio overlay) in one view, not five tabs.
