Clavix Risk Report · October 19, 2026

The riskiest and safest US stocks right now

Every trading day, Clavix grades 1,019 US stocks and ETFs A+ to F by combining four weighted risk dimensions: price stability, macro resilience, news sentiment and sector resilience. A fifth, financial health, is scored and shown next to the grade and carries no weight in it. This report ranks that universe by composite risk score as of October 19, 2026. Higher scores mean lower risk. It is an educational risk read, not investment advice.

As of October 19, 2026, the highest-risk name in the covered universe is Fuelcell Energy Inc (FCEL) at a F (11.9/100), and the lowest-risk is iShares 1-3 Year Treasury Bond ETF (SHY) at a A+ (96.6/100). By sector, Leisure Products carries the highest average risk and Dividend Equity the lowest.

How to read this

Each grade is a weighted composite of four independently scored dimensions, remapped to a fixed A+ to F scale so the meaning never drifts. A low grade flags elevated risk as Clavix measures it today; it is not a prediction that a stock will fall, and a high grade is not a prediction that one will rise. Read the full grading methodology, or see any name in the stock risk directory.
