Modern portfolio theory (MPT) is an investment frameworkthat focuses on maximizing returns while minimizing risk by constructing adiversified portfolio. It was developed by economist Harry Markowitz in the1950s and has since become a cornerstone of investment management.
The key idea behind MPT is that an investor should notsolely focus on the individual performance of each investment but ratherconsider how these investments interact as a whole. By diversifying acrossvarious asset classes and spreading investments, the theory aims to reduce theimpact of any single investment's performance on the overall portfolio.
MPT revolves around two important concepts: expected returnand risk. Expected return refers to the potential gain an investor anticipatesfrom an investment, while risk represents the uncertainty or volatilityassociated with that investment. According to MPT, investors should aim toachieve the highest expected return for a given level of risk, or conversely,minimize risk for a desired level of return.
To achieve this, MPT suggests that investors shoulddiversify their portfolios across different asset classes, such as stocks,bonds, and commodities, as well as within each class by investing in variousindividual securities. By doing so, they can potentially reduce the riskassociated with any one investment while still seeking to generate attractivereturns.
MPT also emphasizes the importance of analyzing thecorrelation between different investments. Correlation measures how closely theprice movements of two investments are related. Ideally, MPT encourages theinclusion of assets that have a low or negative correlation with each other.This way, if one investment performs poorly, others in the portfolio may helpoffset the losses, leading to a more stable overall portfolio.
In practice, MPT suggests that investors should allocatetheir capital based on their risk tolerance and investment objectives. By diversifyingacross different asset classes and carefully selecting investments with lowcorrelations, investors can aim to achieve a balance between risk and returnthat aligns with their goals.
