Diversification may be thought of as "Di-worse-fication" according to legendary investors like Charlie Munger or Peter Lynch. We explain misconceptions with the popular financial advice to "diversify" your assets, but what does this really mean? People are not necessarily diversified enough within a country or asset types, so there are many factors to consider. The best investors like Warren Buffett prefer to have high concentration in a few assets, which could still have some amount of diversification but not an overwhelming amount. Different strategies work for different mindsets as the "know-nothing" investor may be better off with a Buffett recommendation in a low-cost S&P 500 index fund.
