Modern portfolio theory – Wikipedia

There many other risk measures like coherent risk measures might better reflect investors’ true preferences. Specific risk is the risk associated with individual assets – within a portfolio these risks can be reduced through diversification specific risks “cancel out”. If nuclear engineers ran risk management this way, they would never be able to compute the odds of a meltdown at a particular plant until several similar events occurred in the same reactor design.

In other words, investors can reduce their exposure to individual asset risk by holding a diversified portfolio of assets. When the self attributes comprising the self-concept constitute a well-diversified portfolio, then psychological outcomes at the level of the individual such as mood and teoira should be more stable than when the self-concept is undiversified.

This risk is only an opportunity to buy or markiwitz assets at attractive prices inasmuch as it suits one’s book. A PRA is what economists would call a structural model.

This prediction has been confirmed in studies involving human subjects. Mathematical Finance, 19 3 And, unlike the PRA, if there is no history of a particular system-level event like a liquidity crisisthere is no way to compute the odds of it.

Corrections All material marowitz this site has been provided by the respective publishers and authors. One key result of the above analysis is the two mutual fund theorem.

The risk, return, and correlation measures used by MPT are based on expected valueswhich means that they are mathematical statements about the future the expected value of returns is explicit in the above equations, and implicit in the definitions of variance and covariance. Diversification may allow for the same portfolio expected return with reduced risk. Portfolio selection with monotone mean-variance preferences. More fundamentally, investors are stuck with estimating key parameters from past market data because MPT attempts to model risk in terms of the likelihood of losses, but says nothing about why those losses might occur.


In practice, short-term government securities such as US treasury bills are used as a risk-free asset, because they pay a fixed rate of interest and have exceptionally low default risk. This efficient half-line is called the capital allocation line CALand its formula can be shown to be.

Examples of implementation of the critical line algorithm exist in Visual Basic for Applications [5]in JavaScript [6] and in a few other languages. MPT derives the required expected return for a correctly priced asset in this context.
