Capital Market Line
The capital market line is a graphical representation of the risk-return trade-off for efficient portfolios, specifically those that are perfectly diversified. It is the line that connects the risk-free rate to the market portfolio, which contains all risky assets in the market.
Any portfolio lying on the capital market line is considered optimal because it provides the highest possible expected return for a given level of total risk. In the crypto context, this line serves as a benchmark for comparing the performance of active management strategies.
If a strategy consistently underperforms the capital market line, it suggests that the active management is not adding value relative to the risk taken. It provides a clear target for investors looking to achieve market-efficient returns.
The line helps in understanding the role of systemic risk and the limits of diversification. It is a cornerstone of modern financial theory applied to capital allocation.
