Passive portfolio strategy

A strategy that involves minimal expectational input, and instead relies on

The expected return/standard deviation pairs of all portfolios that can be
constructed from a given set of assets.

Alpha

A measure of selection risk (also known as residual risk) of a mutual fund in relation to the market. A
positive alpha is the extra return awarded to the investor for taking a risk, instead of accepting the market
return. For example, an alpha of 0.4 means the fund outperformed the market-based return estimate by 0.4%.
An alpha of -0.6 means a fund's monthly return was 0.6% less than would have been predicted from the
change in the market alone. In a Jensen Index, it is factor to represent the portfolio's performance that
diverges from its beta, representing a measure of the manager's performance.
