Find Stocks That Survive Chaos

The anti-fragility screener that asks "what can kill this company?" — not "what's the growth story?" Screen for survival, not hype.

Traditional Screeners Have It Backwards

Most tools chase growth narratives. We focus on what actually matters for long-term wealth: not blowing up.

Growth-Chasing Approach

  • × "What's the upside potential?"
  • × Chases momentum and narratives
  • × Ignores balance sheet risks
  • × One bad quarter = portfolio disaster

Anti-Fragility Approach

  • "What can kill this company?"
  • Screens for survival first
  • Deep dive into debt, cash flow, runway
  • Chaos = opportunity to buy more

The 5 Dimensions of Anti-Fragility

Every stock is scored across 5 critical dimensions. Each score ranges from 0-10. Together, they reveal whether a company can survive — or will crumble under pressure.

Leverage Score

How much debt does the company carry? Can they service it?

High score (8-10) Debt-to-Equity ≤0.3
Low score (0-3) D/E >5x, weak coverage

Cash Flow Score

Are earnings backed by real cash, or accounting tricks?

High score (8-10) FCF margin ≥25%
Low score (0-3) Negative FCF

Survival Score

How long can they survive without external financing?

High score (8-10) Years of runway
Low score (0-3) Months of runway

Failure Mode Score

What concentration risks could kill the business?

High score (8-10) Low intangibles, diversified
Low score (0-3) Acquisition-heavy

Robustness Score

Overall operational and financial strength combined.

High score (8-10) Net cash, strong equity
Low score (0-3) Negative flexibility

The Anti-Fragility Scale

Every stock gets classified into one of four categories. This tells you instantly whether it's built to survive — or destined to crumble.

80+ Anti-Fragile

Benefits from disorder. Can deploy capital when others are panicking. These are the companies you want to own through chaos.

60-79 Robust

Survives any stress. Solid balance sheet, real cash flows. Won't thrive in chaos, but won't die either.

40-59 Fragile

Harmed by stress. Weaknesses that need monitoring. Position sizing is critical here.

<40 Highly Fragile

Existential risk. One bad quarter could be fatal. Avoid or short.

Position Sizing That Protects You

The Taleb scoring system doesn't just classify stocks — it tells you exactly how much of your portfolio to risk. Because surviving is more important than winning big.

Decision Band Taleb Score Max Position What It Means
Reject 0-50 0% Do not invest. Too many ways to die.
Micro Only 50-65 ≤0.25% Tiny position. Lottery ticket only.
Speculative 65-75 ≤0.5% Calculated bet. Upside potential with risk.
Rare Opportunity 75+ ≤1% Strong conviction. Asymmetric upside.

Position sizes are maximums. Your actual allocation depends on portfolio construction and correlation.

Focus on what can kill a company, not what can make it succeed. Survival is the prerequisite for compounding.

Not Another Generic Screener

TradingView, Finviz, and Yahoo Finance show you the same metrics everyone else sees. We show you what they're missing.

Real SEC Data

Direct from 10-K and 10-Q filings via SEC EDGAR. Not aggregator feeds that can be stale or wrong.

Insider Tracking

SEC Form 4 filings reveal who has skin in the game. Founders buying = confidence. Officers dumping = warning sign.

Asymmetry Detection

Find stocks with option-like payoffs: limited downside, 5-10x upside potential. The holy grail of Taleb investing.
