Investors cannot accurately calculate true returns on leveraged portfolios because volatility drag calculations are complex and error-prone

Sophisticated investors using leverage (margin, options, futures) struggle to determine their actual geometric returns because volatility drag—the performance drag caused by compounding losses during market swings—is mathematically complex and poorly documented. Existing financial calculators and spreadsheets either ignore volatility drag entirely or implement it incorrectly, leading investors to overestimate their real returns and make poor capital allocation decisions based on flawed performance metrics.
