What the KC Score says about Costco
Costco (COST) currently carries a KC Score of 31 out of 100 — a grade of D+. In plain terms: soft — price is below key averages and momentum is fading. The score is a transparent, rules-based read of roughly the last twelve months of Costco's daily closing prices. It describes momentum, trend, range position and stability — it is not a buy or sell recommendation, and it knows nothing about Costco's valuation, earnings or news. At the last hourly update the stock traded near USD904.70, up 0.7% on the session, sitting 24% of the way up its 52-week range and about 17.5% below its 52-week high.
Momentum scores 40 out of 100. Over the past three months Costco has moved -5.9%, and -7.1% over six months — a decline over both windows that weighs the momentum reading down. On trend (4/100), the price is below its 50-day moving average and below its 200-day average. Trading below both averages is the shape the model reads as a downtrend.
Range position scores 24/100: at 24% of its 52-week band, Costco is trading toward the lower end of where it has been over the last year. Stability scores 93/100, off annualised volatility of about 20% — relatively low for a single stock. Lower volatility means steadier day-to-day movement, though it is never a guarantee against a large fall.
For a long-term investor, one stock's score matters far less than the system around it: keeping costs low, staying diversified, and giving compounding time to work. Treat COST's reading as a single input, not a verdict, and compare it against other Retail names rather than in isolation. The math always wins — a low-cost, broadly diversified portfolio held for years reliably beats reacting to any one score, including this one.
