Costco's 0.45% earnings yield versus 4.33% Treasuries violates Graham's first principle — never accept risk for inferior returns.

Applying Benjamin Graham's published criteria reveals a superb business trading at a price that violates every principle of intelligent investing.

Does the stock yield meaningfully more than government bonds? If not, why accept equity risk when a safer alternative pays more?

The framework's fundamental test fails decisively — an investor receives 0.45% for equity risk while Treasury bonds pay 4.33% with no risk. This 3.88 percentage point deficit means accepting downside risk for inferior returns, violating the first principle of intelligent investing.

Has this company earned money consistently over 7-10 years, or are its profits volatile and unpredictable?

The business demonstrates textbook earnings stability with predictable revenue growth from membership fees and consistent operating performance. This framework values such reliability highly, though stability alone cannot overcome price.

At the current price, how much room is there for error? If the business disappoints, does the price protect the investor from permanent loss?

No margin of safety exists — the price assumes perfection in perpetuity. At 224% above calculated fair value and P/E at decade highs, any disappointment risks permanent capital loss. The framework demands protection; this price offers exposure.

Is the company financially strong enough to survive a prolonged downturn? What do the current ratio, debt levels, and interest coverage say about solvency?

The balance sheet represents a fortress — negative net debt, strong cash generation, and exceptional working capital efficiency. This framework recognizes financial strength but notes that balance sheet quality cannot overcome valuation excess.

Through Benjamin Graham's published framework, Costco emerges as a superb business available at an unintelligent price. The 0.45% earnings yield versus 4.33% Treasury bonds fails the framework's fundamental test — why accept equity risk for inferior returns? While the balance sheet fortress and 92.1% renewal rates confirm business quality, paying 55.5x earnings with no margin of safety violates core principles. At what earnings yield would this framework consider the defensive qualities fairly priced?
