07 — Finance & Investing

Value Investing.
Three Frameworks.
One Integrated Verdict.

Beyond cloud engineering, value investing is my personal passion. I built this platform to combine my love for technology with my fascination for finance and the stock market — evaluating every company through Graham's intrinsic value, Buffett's durable competitive advantage, and Sowell's economic context. Three independent perspectives — one integrated verdict.

Investing with a single framework is like looking at a company with one eye. This approach combines three perspectives that together create a complete three-dimensional picture.

🏛️

Benjamin Graham

Is the PRICE right? Intrinsic value, 33% margin of safety, investment vs. speculation classification. The quantitative discipline that prevents you from overpaying.

🎩

Warren Buffett

Is the COMPANY exceptional? Durable competitive advantage, owner earnings, consistent ROE, gross margins >40%. The quality filter that ensures decades of earnings.

📈

Thomas Sowell

Does the CONTEXT favor it? Price signals, natural vs. artificial competition, government distortions. The macro radar that detects invisible threats.

How It Works

01 · Graham Filters by Price

Calculates intrinsic value with mathematical formulas. Demands a 33% margin of safety. Classifies as investment or speculation based exclusively on quantitative data.

02 · Buffett Filters by Quality

Evaluates durable competitive advantage. Consistent ROE >15%. Gross margins >40%. Low CAPEX. Buybacks. Can this company defend its earnings for decades?

03 · Sowell Filters by Environment

Analyzes price signals, competition, government distortions, incentives, and systemic risks. Do external forces favor or threaten the company?

04 · Only When All Three Say "Yes"

Triple convergence drastically reduces the risk of error. If one says "no" — you wait. If two say "no" — you avoid. Only complete alignment generates a buy signal.
