YTD Performance +14%
Trailing Year +97% to +262%
Recent Action Acquired Skyloom
🏆 Best Approach: REALISM WINNER
Exit Strategy Based on Objective Fundamentals
  • Why Realism Won: Focused on objective reality - $446M insider selling signals true company insiders' view
  • Austrian Failed: Looked for malinvestment but missed timing on correction
  • Keynesian Misread: Betting on gov't intervention narrative proved premature
  • Marginalism Partial: Risk-adjusted position sizing helped, but didn't predict scale of correction
  • Pragmatic Worked: "Truth as what works" approach validated exit based on evidence
  • Realist Insight: Truth correspondence - insider actions contradicted stock price, signaling objective reality

-3% to -8% Week
YTD Performance +62%
Trailing Year +1,590% to +2,810%
Insider Activity $45.6M net selling
🏆 Best Approach: AUSTRIAN ECONOMICS WINNER
Classic Malinvestment Identification
  • Why Austrian Won: Textbook malinvestment case - massive gains from artificial credit-induced boom, extreme P/S 300x+
  • Realism Partial: Identified overvaluation but harder to time exact correction
  • Keynesian Failed: Animal spirits suggested contrarian buy at extremes - wrong timing
  • Marginalism Helped: Diminishing marginal returns visible at peak

YTD Performance +170%
Trailing Year +1,420% to +3,060%
Insider Activity $224M net selling
🏆 Best Approach: PRAGMATISM WINNER

  • Austrian Identified: Malinvestment but P/S 350x harder to act on without pragmatic risk rules
  • Keynesian Trap: Beauty contest thinking kept investors hoping for "greater fool"
  • Marginalism Good: Position sizing helped but needed pragmatic exit rules
  • Realism Warning: Insider selling $224M should have triggered exit
  • Pragmatic Discipline: 1-2% position sizing, stop losses, accepting "being wrong" preserved capital
QUBT - Quantum Computing Inc.
+8.5% Week
YTD Performance -30%
Trailing Year +627% to +1,260%
Q3 Revenue $384K (+280% YoY)
🏆 Best Approach: KEYNESIAN WINNER
Animal Spirits Contrarian Play
  • Why Keynesian Won: Extreme fear after -42% drop from high created contrarian buy opportunity before earnings
  • Austrian Concerned: Viewed as ultimate malinvestment with minimal revenue
  • Realism Skeptical: Fundamentals weak ($384K revenue)
  • Marginalism Opportunity: Marginal opportunity cost high vs other oversold names
  • Pragmatic Validation: Earnings beat provided concrete results
  • Keynesian Insight: Animal spirits oversold, sentiment extreme fear created short-term bounce +8.5%
QTUM - Defiance Quantum ETF
-1% to -3% Week
Price Nov 18 $104.02
YTD Return +62.45%
AUM $3.03B
🏆 Best Approach: MARGINALISM WINNER
Diversification & Risk-Adjusted Returns
  • Why Marginalism Won: Marginal utility of diversification outperformed individual stock risk
  • Austrian Benefit: Diversification across stages reduced single malinvestment exposure
  • Keynesian Smoothing: ETF structure dampened animal spirits extremes
  • Realism Validation: Mix of MSFT, GOOGL, NVDA with pure-plays = objective balance
  • Pragmatic Sense: "Don't put all eggs in one basket" proven right
  • Marginalist Insight: Diminishing marginal returns from concentrated bets avoided, -3% vs -40% individual stocks
