Is the business good?
A genuinely good business: earnings fully cash-backed (1.3×) and margins widening.
Mixed fundamental signals. Nine pass/fail tests of year-over-year health from the filings.
Operating profit is fully backed by cash.
Positive operating leverage, operating profit is growing faster than sales, so margins widen as the business scales.
Margin-driven, fat margins on slower asset turns. ROE 17% = margin × turnover × leverage.
Unless marked, from derived.
