Return per unit of risk over the last 90 days
Sharpe (90d) asks how much recent return the asset delivered per unit of volatility over roughly the last three months. It is a speedometer for efficiency, not just raw performance.
A high Sharpe means the recent payoff looked efficient relative to total noise. It does not prove the move is durable, cheap, or safe outside that short window.
Technical definition, calculation notes and sources stay available here without dominating the explanation.
The Sharpe ratio relates return to risk.
Higher values occur when an asset delivered returns while moving relatively smoothly (with less volatility).
We use a short 90-day window. It reacts quickly to market regimes, but it’s also more sensitive to short-term outliers.
Important: in this simplified variant we don’t subtract an explicit risk-free rate - it’s mainly meant for comparisons within this universe.
Use the ranking after the explanation, not as a standalone investment signal.

Compare it with Sortino (90d) to see whether downside-only risk tells a different story than total volatility.
Use Volatility (365d, annualized) to see whether the broader recent risk backdrop matches the 90-day efficiency read.
Use Return 1 Year to see whether short-term efficiency also translated into stronger longer-window outcome.
