When you're deciding between two stocks, the question isn't "which one has a lower P/E?" The question is "which one has the better combination of moat, durability, management, valuation, and resilience?" That's a 7-metric framework, not a single-ratio comparison.
This post walks through the 7 metrics that matter in any two-stock comparison, with Apple (AAPL) vs Microsoft (MSFT) as the worked example. (You can view this comparison live with current numbers at /compare/aapl-vs-msft/ on invest-like.)
The 7 metrics
Each metric maps directly to one of the 5 Buffett pillars + price + risk:
| # | Metric | What it measures | Pillar |
|---|
| 1 | ROIC trend (10y) | Capital efficiency stability | Moat |
| 2 | Gross margin stability | Pricing power, durability | Durability |
| 3 | Buyback timing | Capital allocation quality | Management |
| 4 | Owner-earnings yield | Price reasonableness | Valuation |
| 5 | Current ratio + debt | Balance-sheet resilience | Health |
| 6 | Revenue concentration | Single-customer / single-product risk | Risk |
| 7 | Forward earnings consensus | Market expectation | Cross-check |
Every two-stock comparison should walk through all seven. Stopping at "lower P/E wins" is the same mistake that produces value traps.
Apple vs Microsoft, metric by metric
Metric 1: ROIC trend (10-year)
- Apple: ROIC has been in the 25-50% range for the last decade. Currently very high (~130%+) due to buyback-driven equity compression. Trend = strong throughout.
- Microsoft: ROIC has been 18-30% range for the last decade. Currently ~30%. Trend = improving over the cloud-transition decade.
Winner: Apple on absolute level. Microsoft on trend slope (improving vs holding).
Interpretation: Apple is a steady high-ROIC compounder. Microsoft has had a re-rating story (cloud) that took it from 15% ROIC to 30%. If you believe more re-rating is possible (AI), MSFT is the better forward bet. If you believe AAPL's franchise is durable, AAPL is the safer steady bet.
Metric 2: Gross margin stability
- Apple: gross margin has expanded from ~38% (2014) to ~46% (2024). Stable upward trend driven by services mix increase.
- Microsoft: gross margin has expanded from ~63% (2014) to ~70% (2024). Cloud high-margin contribution.
Winner: Microsoft on absolute level (70% vs 46%). Both have positive trend.
Interpretation: Microsoft is a higher-quality margin profile in absolute terms. The 24% margin gap is a structural reflection of software-only vs hardware-+-services.
Metric 3: Buyback timing
- Apple: spent $97.7B on buybacks in fiscal 2024. Cumulative buyback over the last decade: roughly $700B+. The buyback has been opportunistic - increased during 2018 and 2020 weakness, slowed during stronger periods.
- Microsoft: spent $17.7B on buybacks in fiscal 2024. More modest pace. Steady cadence regardless of price.
Winner: Apple on aggressiveness and timing discipline. Microsoft on capital prudence (avoiding overpayment during strength).
Interpretation: Apple's buyback is one of the most-disciplined capital-allocation programs in the S&P 500. Microsoft's is more methodical but less opportunistic. Different management styles.
Metric 4: Owner-earnings yield (Buffett's preferred valuation)
- Apple: owner earnings ~$99.7B on market cap ~$3,400B = 2.93% yield.
- Microsoft: owner earnings ~$78B on market cap ~$3,100B = 2.52% yield.
Winner: Apple by a hair (3% vs 2.5%).
Interpretation: Both fail Buffett's 5% floor for stable businesses. Microsoft fails harder. Either you accept the "wonderful business at unfair price" framing (Munger), or you wait.
Metric 5: Current ratio + debt
- Apple: current ratio ~1.0 (low by Graham standards), but $171B of cash and marketable securities. Net cash position is positive ($170B+). Debt-to-equity ratio ~1.5 (high, but supported by cash).
- Microsoft: current ratio ~1.7. Net cash also positive. Debt-to-equity ratio ~0.6 (cleaner).
Winner: Microsoft on Graham's defensive criteria. Apple is fortress-safe but only because of the cash pile, not because of balance-sheet discipline.
Interpretation: Both pass any reasonable solvency test. Microsoft passes the Graham defensive screen more cleanly. Apple needs the cash interpretation.
Metric 6: Revenue concentration
- Apple: iPhone is ~51% of revenue. Single-product concentration is real. Services + Mac + iPad + Wearables make up the other ~49%.
- Microsoft: Cloud (Azure + AI) is ~38%. Productivity & Business Processes (Office) ~30%. Personal Computing ~25%. Gaming ~7%. Much more diversified.
Winner: Microsoft by a clear margin.
Interpretation: Apple's revenue is more concentrated. If iPhone replacement cycles extend dramatically (or smartphones get disrupted), Apple has a single-product reset to absorb. Microsoft's diversified mix is structurally more resilient.
Metric 7: Forward earnings consensus
- Apple: forward EPS growth consensus ~7% (next 2 years).
- Microsoft: forward EPS growth consensus ~12-15% (next 2 years, AI-driven).
Winner: Microsoft on forward growth rate.
Interpretation: The market expects Microsoft to grow faster than Apple over the next 2 years. If that materialises, MSFT is the better forward bet. If AI capex margins compress and growth disappoints, MSFT becomes overvalued faster than AAPL.
The summary scorecard
Apple wins 2 of 7 (ROIC absolute level, owner-earnings yield). Microsoft wins 5 of 7 (gross margin, buyback prudence, current ratio, revenue diversification, forward growth).
But the two metrics Apple wins are foundational ones: capital efficiency and price. The five metrics Microsoft wins are sustaining metrics that compound the headline numbers.
The honest read: Microsoft is the better business forward; Apple is the better business currently and historically. Both pass 6-of-7 frameworks on our consensus screen. The choice between them depends on whether you weight forward growth (favoring MSFT) or current cash generation (favoring AAPL).
What the comparison page does
The /compare/aapl-vs-msft/ page on invest-like surfaces all 7 metrics side-by-side with live data, plus the 7-framework consensus comparison and the Boardroom debate transcript. The intent is exactly the comparison this post walks through - but with current numbers and the supporting evidence one click away.

How to use this in your own analysis
When you're stuck between two stocks:
- Open /compare/-vs-/ on invest-like
- Walk through each of the 7 metrics above
- Identify which metric you weight most heavily (different investors weight differently)
- Make your call
The 7-metric framework is more robust than the single-ratio comparison ("AAPL has lower P/E, AAPL wins") that most retail analysis collapses to.
