The Post-Modern Portfolio Theory (PMPT)

The post-modern portfolio Theory (PMPT) is a portfolio optimization methodology that uses the strike threat of returns rather than the mean friction of investment returns used by the ultramodern portfolio Theory (MPT). Both Theory describe how parlous means should be valued, and how rational investors should use diversification to achieve portfolio optimization. The difference lies in each Theory’s description of the threat, and how that threat influences anticipated returns. 

  • The Post-modern portfolio Theory (PMPT) is a methodology used for portfolio optimization that utilizes the strike threat of returns. 
  • The PMPT stands in discrepancy to the ultramodern portfolio Theory (MPT); both of which detail how parlous means should be valued while stressing the benefits of diversification, with the difference in the Theorys being how they define the threat and its impact on returns.
  • •BrianM. Rom and Kathleen Ferguson, two software contrivers, created the PMPT in 1991 when they believed there to be excrescencies in software design using the MPT. 
  • The PMPT uses the standard divagation of negative returns as the measure of threat, while the ultramodern portfolio Theory uses the standard divagation of all returns as a measure of threat. 
  • The Sortino rate was introduced into the PMPT rubric to replace MPT’s Sharpe rate as a measure of threat- acclimated returns and bettered upon its capability to rank investment results. 


  • The Post-Modern portfolio Theory (MPT) is a system that can be used by threat-antipathetic investors to construct diversified portfolios that maximize their returns without inferior situations of threat. 
  • The Post-Modern portfolio Theory can be useful to investors trying to construct effective and diversified portfolios using ETFs. 
  • Investors who are more concerned with strike threats might prefer the post-modern portfolio Theory (PMPT) to MPT. 

Criticism of the MPT 

Maybe the most serious review of the MPT is that it evaluates portfolios grounded on friction rather than strike threat. That is, two portfolios that have the same position of friction and returns are considered inversely desirable under the ultramodern portfolio Theory. One portfolio may have that friction because of frequent small losses. Another could have that friction because of rare but spectacular declines. utmost investors would prefer frequent small losses, which would be easier to endure.

The post-modern portfolio Theory (PMPT) attempts to ameliorate an ultramodern portfolio Theory by minimizing strike threat rather than friction. Difference Between the Modern Portfolio Theory and the Post-Modern Portfolio Theory The post-modern portfolio Theory (MPT) was an advance in particular investing. It suggests that a conservative investor can do better by choosing a blend of low-threat and unsafe investments than by going entirely with low-threat choices. More importantly, it suggests that the more satisfying option doesn’t add a fresh overall threat. This is the crucial trait of portfolio diversification.  The post-modern portfolio Theory (PMPT) doesn’t contradicts these introductory hypotheticals. still, it changes the formula for assessing threats in investment to correct what its inventors perceived as excrescencies in the original.  Followers of both Theory use software that relies on either MPT or PMPT to make portfolios that match the position of threat that they seek.  the Benefits of the Modern Portfolio Theory The ultramodern portfolio Theory can be used to diversify a portfolio to get a better return overall without a bigger threat.

Another benefit of the modern portfolio Theory (and of diversification) is that it can reduce volatility. The stylish way to do that’s to choose means that have a negative correlation, similar as U.S. coffers, and small-cap stocks.  Eventually, the thing of the ultramodern portfolio Theory is to produce the most effective portfolio possible.  The effective frontier is the foundation of the ultramodern portfolio Theory. It’s the line that indicates the combination of investments that will give the loftiest position of return for the smallest position of threat. When a portfolio falls to the right of the effective frontier, it possesses lesser threat relative to its prognosticated return. When it falls beneath the pitch of the effective frontier, it offers a lower position of return relative to threat.
