Enterprising
Defensive — Graham's strict criteria (P/B, P/E, dividends, stability)  ·  Enterprising — Profitability & cash flow focused, accepts higher valuations for quality
Metric Explanations
What each dimension measures and where the thresholds come from.
Gross Profit Margin
Revenue minus cost of goods sold. Graham's ≥40% threshold identifies businesses with durable pricing power. Note: software and financial companies naturally exceed this; retailers and manufacturers rarely reach it due to their cost structures.
Operating Margin
Profit after operating costs before interest and taxes. A consistent ≥15% operating margin signals a business with real competitive advantages. Capital-intensive industries (airlines, auto, commodities) rarely hit this threshold due to their structural cost base — compare within industry for context.
Net Income Margin
Bottom-line profit as a percentage of revenue. The ≥20% target reflects Buffett's preference for highly profitable businesses. Financial engineering (buybacks, tax optimisation) can inflate this temporarily — look for consistency across multiple years rather than a single strong result.
Working Capital
Current Assets minus Current Liabilities. Negative working capital can be a deliberate efficiency strategy in businesses that collect cash before paying suppliers (retailers, fast food franchises, subscription businesses). Assess alongside free cash flow generation for full context.
Margin of Safety
How far below the Graham Number the stock trades. Graham required a 33% discount as a buffer against analytical error. However, the Graham Number itself assumes 1960s-era P/E and P/B norms — for modern asset-light businesses it often understates true intrinsic value, making 0% MoS appear misleadingly bad.
Price-to-Book
Market price vs book value per share. Rarely below 1.5x for quality businesses today. Intangible assets (brand, software, patents) don't appear on the balance sheet under accounting rules, making P/B artificially high for asset-light companies. Negative P/B indicates book equity has been reduced by buybacks — common in highly profitable capital-return businesses.
Free Cash Flow
Operating cash flow minus capital expenditures. Buffett's most important metric — cash a business actually generates for its owners after maintaining and growing its asset base. Consistently positive FCF is one of the strongest indicators of a durable, well-run business regardless of accounting profits.
CapEx % of Net Income
Capital expenditure as a share of net income. Low CapEx signals a capital-light business that doesn't need heavy reinvestment to sustain earnings — Buffett's ideal. High CapEx is structurally necessary in manufacturing, airlines, telecoms, and semiconductors. For these industries, a high reading reflects the business model, not poor management.
Owner Earnings
Net Income + Depreciation & Amortisation − Capital Expenditures. Buffett's preferred measure of a company's true annual earning power — what could theoretically be distributed to owners without impairing the business. More reliable than reported EPS because it accounts for the capital cost of maintaining the business.

Full Graham Analysis

Mr. Market is currently offering Intuitive Surgical, Inc. at $452.35.

The business passes 4 of 7 of Graham's defensive criteria — adequate but not exceptional.

At $452.35, the stock trades at a 379% premium to its Graham Number of $94.40. Graham would consider this price speculative.

There is no margin of safety at the current price. Graham would advise patience and waiting for a better entry point.

Trading at 22.1x NCAV. Expected for most quality businesses — NCAV was designed to find depression-era bargains and rarely applies to modern profitable companies..

Conclusion: This stock is better suited for Graham's Enterprising investor — one willing to devote time and skill to security selection.

These metrics estimate what Intuitive Surgical, Inc. is worth based on its fundamentals — independent of what the market currently prices it at. Graham's Fair Value and NCAV are conservative floors rooted in 1930s–60s principles. EPV assumes zero growth. None are price targets — they are reference points for judging whether the current price offers a margin of safety.

Graham's 7 Criteria — Explained
What each criterion measures and why it may or may not apply to modern businesses.
✅ Adequate Size — $10.1B vs > $1.5B revenue
Graham required companies large enough to withstand economic downturns. This threshold ($1.5B) is inflation-adjusted from Graham's original $100M — virtually all S&P 500 companies pass this today.
"The minimum size of an enterprise should be not less than $100 million of annual sales."
✅ Strong Financial Condition — 4.87x vs Current Ratio > 2.0x
Current assets must be at least twice current liabilities. Note: highly profitable companies (Apple, Domino's) often run negative or low working capital deliberately — they collect cash fast and stretch payables. A failing score here is not always a warning sign.
"For industrial companies, current assets should be at least twice current liabilities."
✅ Earnings Stability — No loss years (4 yrs data) vs No negative EPS years
Graham required uninterrupted positive earnings. Any loss year is a red flag for defensive investors. Growth companies and cyclicals may show occasional losses during investment cycles or downturns without being fundamentally unsound.
"The company should have shown no deficit in the past ten years."
❌ Dividend Record — No dividend vs Uninterrupted dividends
Graham valued dividends as evidence of financial discipline and shareholder alignment. Many excellent modern businesses (Alphabet, Amazon, Berkshire Hathaway) pay no dividend, preferring to reinvest cash at high rates of return. Failing this criterion does not indicate a poor business — it may indicate a high-growth one.
"Some current dividend payments — for at least the past 20 years."
✅ Earnings Growth — +115.6% EPS growth vs > 33% EPS growth
EPS grew from $3.65 to $7.87 over 3 years. Graham's 33% threshold was set over a 10-year period. Measured over fewer years (as here), the bar is proportionally lower. Share buybacks can also inflate EPS growth without reflecting underlying business improvement.
"A minimum increase of at least one-third in per-share earnings over ten years."
❌ Moderate P/E Ratio — 54.9x vs P/E ≤ 15.0x
Graham's 15x P/E threshold was calibrated to 1960s market averages when interest rates were higher. Today's lower rate environment structurally supports higher multiples — the S&P 500 long-run average P/E is now closer to 20–25x. A stock trading at 20x is not automatically speculative in the modern context.
"The price-earnings ratio should be no more than 15 times average earnings."
❌ Moderate Price-to-Book — 8.99x P/B (P/E×P/B: 493.4) vs P/B ≤ 1.5x | P/E × P/B ≤ 22.5
Graham's 1.5x P/B threshold made sense when most company value was tangible. Today, intangible assets — brand, software, patents, network effects — rarely appear on the balance sheet. A high P/B in tech, pharma, or consumer brands often reflects intangible value, not overvaluation. P/FCF or EV/EBITDA are more reliable for asset-light businesses.
"The price should not be more than 1½ times book value. P/E × P/B ≤ 22.5."
