BSXBoston Scientific
Is the business good?
A genuinely good business: 7 of 9 health tests passed, earnings fully cash-backed (1.1×), and margins widening.
High fundamental quality. Nine pass/fail tests of year-over-year health from the filings.
Operating profit is fully backed by cash. Conversion is worsening vs a year ago.
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 13% = margin × turnover × leverage.
Unless marked, from derived.
Against the whole market›
Percentile against every name Ryufin tracks. Higher is better; the tick marks the middle of the market. Context, not one of the checks above.
Where this answer is blind. The F-score rewards improvement, so an already-elite company can score mid-pack.
