Data limitations

• Bias-tagged assets: current large-cap basis — survivorship bias exists
• High risk-tagged assets: crypto is extremely volatile
• Precious metals: futures basis — rollover costs not reflected
• Crypto: from Binance listing date (differs from BTC's actual first trade in 2009)
• Green years (20+): suitable for long-term analysis
• White years (10-20): includes major crisis periods
• Gray years (under 10): limited analysis window
• Fees and FX spreads not reflected
