Portfolio Theory Modern portfolio theory originated with the work of Markowitz (1952), who recognized that by combining assets that are not perfectly correlated (for example, assets whose returns do not move in complete unison with each other) an investor could reduce his or her investment risk without reducing expected returns. MPT - Modern Portfolio Theory - represents the mathematical formulation of risk diversification in investing, that aims at selecting a group of investment assets which have collectively lower risk than any single asset on its own. Portfolio diversification, in terms of exploiting multiple species or populations, has been shown to stabilize interannual variability in commercial fisheries and fishing communities 6,11,20,21,22. The implications of these findings for both the port- folio manager and the investor are significant. where in the Hebrew bible it quotes "But divide your investments among many places, for you do not know what […]. The idea derives from Modern Portfolio Theory (MPT), developed by Harry Markowitz in the 1950s, for which he shared the Nobel prize in Economics in 1990. It may even call for concentration, if not of one’s portfolio, then atleast of its owner’s mind. To illustrate the value of this sort of diversification, consider the period often referred to as the “lost decade” by the financial press. You're probably familiar with the saying "don't put all your eggs in one basket", a short but effective analogy for explaining diversification. Maximum Diversification Theory Maximum diversification theory also uses volatility to measure risk. Developed through time-tested finance research, modern portfolio theory seeks to increase investment return while lowering risk. Large insurance, hedge funds, and asset managers base their investment decisions on modern portfolio theory. Diversification strives to smooth out unsystematic risk events in a portfolio so that the positive performance of some investments will neutralize the negative performance of others. A rule of conservative investing is not putting all of your investment eggs in one basket.
