After-Tax Risk Adjusted Return
After-tax risk-adjusted return is a performance metric that evaluates the profitability of an investment or derivative strategy after accounting for both tax liabilities and the volatility of the asset. It provides a more accurate picture of net wealth accumulation than gross return metrics.
By adjusting for tax, traders can compare the true economic utility of different instruments, such as holding Bitcoin versus trading options on a centralized exchange. The calculation incorporates the marginal tax rate, the cost of capital, and the volatility of the position.
This metric is essential for professional traders who must justify the risk taken in adversarial market environments. It highlights the impact of tax drag on compounding returns over time.
A strategy that appears profitable on a gross basis may yield poor results after taxes and risk adjustments are applied. It is the ultimate benchmark for measuring investment success.
