Color: green = healthy, red = caution (absolute thresholds, value/quality metrics only). Downside vol & Sortino are annualized. Max drawdown = largest drop from a 3-year peak; volatility = 1-year annualized. Price/Graham < 1 = below Graham fair value (profitable, positive-equity names only). RSI < 30 = oversold.
