Boston Scientific has 69% gross margins. Abbott has 56%. Yet Abbott's ROIC is 2.6x higher. This paradox reveals something fundamental about capital efficiency in medical devices—and why screening for 'high margin' stocks can lead you astray.
The conventional wisdom says Visa is the safer, higher-quality payment stock. Our ROIC analysis tells a different story: Mastercard's 78% ROIC dwarfs Visa's 36%, and the reason reveals something important about how to read these metrics.
Wall Street treats homebuilders as a monolithic 'housing play.' But our analysis reveals a 4x ROIC spread (NVR 35% vs LEN 9%) that cannot be explained by margins alone. The divergence stems from three structural factors: NVR's asset-light lot model vs LEN's Millrose spin-off creating structural margin compression, DHI's $26B in specific performance land contracts creating downside asymmetry, and NVR's paradoxically 'cautious' guidance signaling genuine competitive strength.
Wall Street loves CVNA's +30% ROIC turnaround story. But our 8-quarter trajectory analysis reveals CarMax is in crisis mode: CEO fired December 2025, forced margin cuts, -8% volume decline. The data shows this isn't online vs traditional—it's about execution quality.
Devon Energy generated 48% ROIC in Q3 2025. ExxonMobil generated 11%. Both produce oil and gas. Why the 4.5x difference? The answer lies in capital allocation: XOM returns 73% of FCF as dividends while pure E&P operators reinvest in high-return wells.
Qualcomm's consolidated margins hide a secret: the QTL licensing segment earns 72% operating margin vs QCT hardware's 30%. When Apple moves fully to in-house modems, what happens to QCOM's profitability? Our semiconductor ROIC comparison reveals the answer.
Wall Street ranks Lockheed Martin's 30% ROIC as best-in-class. But our 8-quarter trajectory analysis reveals LMT's capital efficiency is actually declining (-0.018 trend) while RTX improves (+0.004). The data suggests the market may be mispricing defense contractor quality.
