Capital Market Line
Also called: CML, capital allocation line
The capital market line joins the risk-free asset to the tangency portfolio, showing the best return available at each level of total risk once borrowing and lending are allowed. Its slope is the market's Sharpe ratio. Its conclusion is radical and still contested: every investor should hold the same risky portfolio and adjust risk only by mixing it with cash or leverage, rather than by picking different stocks.
