Without a blueprint – you can’t create a house! With out a focal investment strategy most traders (and their financial advisors) make psychological, illogical, and often irrational investment decisions to their own financial detriment. In 1990 Harry M. Markowitz, a teacher at Baruch University of the populous city College or university of New York, won a Nobel Prize in Economic Sciences.
His lifelong studies in the fields of investment risk, investment come back, security relationship and stock portfolio diversification will be the basis of what we realize today as “Modern Portfolio Theory”, or “MPT”. Modern Portfolio Theory is well-known in the investment community as a logical basis for sound portfolio management concepts. Modern Portfolio Theory should serve as a base for your investment planning “blueprint” as well. The crux of Modern Portfolio Theory (MPT) is the relationship between investment risk, come back, and correlation.
Those factors are charted on what’s called the “efficient frontier” graph. The efficient frontier graph illustrates a securities expected return and the chance associated with attaining that expected investment return. On the still left of the efficient frontier graph (the Y axis) is the expected investment come back plotted vertically. The horizontal footing (the X axis) is a dimension of the security’s expected risk (as illustrated by it’s standard deviation). The efficient frontier is a gently sloping arch stretching out up-wards, starting in the low left corner and fading in to the upper right corner. That gently sloping line represents portfolio possibilities providing the utmost long term expectation of profile return, with the least risk (volatility or standard deviation) possible.
A portfolio on the efficient frontier range is reported to be “efficient” or “optimized” to garner the maximum financial benefit for every device of risk exposure. On a single chart as the efficient frontier you might have multiple asset classes plotted in a apparently random fashion. United States treasuries would be plotted with little come back and little risk in the low left part of the X & Y axis.
Asset classes such as growing market equities (stocks and shares) would be plotted in the far upper right corner of the graph representing a high level of risk with a high potential investment come back. USA equities would fall someplace among them representing moderate risk and moderate investment return (when compared to treasuries and growing market equities). Each asset class has a historical “correlation” to another asset class, meaning some investment securities perform differently at different periods in our financial cycle.
For example, in 2008 commodities like silver and essential oil fluctuated wildly both along in value while USA collateral holdings floundered through the third quarter, then sank dramatically in the fourth quarter as commodities stabilized. Treasury bond prices tended to trend down upwards as rates of interest came. These are excellent types of “non-correlation”.
Asset class investments performed good or bad relative to each other, and even though most asset classes ended up reduced value, there have been varying levels of investment loss. The efficient frontier is made up of collection solutions which statistically balance asset course correlations using their expected investment return and risk. These collection solutions are fully varied and contain no securities or investment holdings with specific risk publicity.

It is not possible to have a stock portfolio plotted ABOVE the effective frontier, as it could have corresponding higher expected return and lower expected risk than what is possible given the available information. It really is however possible to have a stock portfolio plotted BELOW the efficient frontier series – or what we should call an “inefficient portfolio”.
The most investors have “inefficient” portfolios, indicating they’re taking on more investment risk than their expected investment come back would require based on available information and objectives for the future. Modern Portfolio Theory says how rational traders use diversification to optimize their investment profile. MPT should theoretically provide an investor with the greatest possible investment come back for just about any given level of investment risk.
Are you spent such as a pro? Or the person? The common Joe buyer throws parts and bits of different shared funds, stocks, exchange traded money, bonds, etc. into a profile and telephone calls it “diversified”. Chances are good, however, they’re actually not thoroughly diversified and haven’t eliminated all the specific risk in their portfolio. In addition, they could or might not have added enough non-correlative asset classes to their investment technique to effectively reduce the systematic risk to the greatest level possible. Modern Portfolio Theory has it’s faults however. The correlation, investment return and risk is situated off historical results and future objectives.
