An example of a positive correlation between shares or options is the price of crude oil and the shares of large oil companies. If the oil price rises, the value of these companies will increase and the shares will also increase in value. If a portfolio consists of an efficient combination ...
a portfolio also has investment risks. The primary objective of portfolio theory or management is to maximize gains while reducing diversifiable risk. Diversifiable risk is so named because the risk can be reduced by diversifying assets.Systemic risk, on the other hand, cannot be reduced...

The Modern Portfolio Theory focuses on the relationship between assets in a portfolio in addition to the individual risk that each asset carries. It exploits the fact that a negatively correlated asset offsets losses that are incurred on another asset. For example,crude oil pricesand airline st...
什么是现代资产组合理论 现代资产组合理论(Modern Portfolio Theory,简称MPT),由马柯维茨提出,也有人将其称为现代证券投资组合理论、证券组合理论或投资分散理论。是将概率论和线性代数的方法应用于证券投资组合的研究,探讨了不同类别的、运动方向各异的证券之间的内在相关性,并于1959年出版了《证券组合选择》一书,详...
What Are Some Examples of Modern Portfolio Theory? At its heart, MPT is a mathematical justification for asset allocation within a portfolio, as it amounts to a weighted average of the expected returns on individual assets. As an example, say an investor has a two-asset portfolio (for simp...
As an example, contrary to what the theory predicts, a researcher in the late 1970s,Sanjay Basu, demonstrated that lowprice-to-earnings ratiostocks outperform high P/E stocks. And in the early 1980s, another researcher,Rolf Banz, demonstrated that small-capitalization stocks outperformed large-ca...
Modern portfolio theory focuses on diversification as a means to build wealth. The theory encourages investors to choose investments that match how much risk they’re willing to take. MPT helps investors build portfolios that align their savings objectives with their risk tolerance. ...
Most importantly, because assets have different risks and for different reasons (bonds tend to go up, for example, when stocks are down), you can actually have a lower level of risk for your portfolio than for each asset individually.3Thus, MPT allows investors to choose a portfolio from th...
Modern portfolio theory takes this idea even further. It suggests that combining a stock portfolio that sits on the efficient frontier with arisk-free asset, the purchase of which is funded by borrowing, can actually increase returns beyond the efficient frontier. In other words, if you were to...
