Do I Need to Sell My Investment? 

In the 1950’s Harry Markowitz published his article “Portfolio Selection” which set the framework for what he dubbed Modern Portfolio Theory (MPT). This theory became so widely adopted that Markowitz was awarded the Nobel Prize in Economics in 1989. A basic tenant of the investment philosophy outlined by MPT says that diversification of portfolios reduces the volatility of the portfolio, which in turn can improve investment performance over multiple market cycles.
