This article is part of our 'Perspectives' series, in which Morningstar features third-party contributions from renowned investment professionals. In this article, Feifei Li, Ph.D., director and head of research at Research Affiliates discusses 'true' diversification.

We learn in finance theory that diversification simply means not putting all your eggs in one basket.

Simple as the idea is, most investors do not hold portfolios that are even close to being truly diversified. Two reasons make this sensible objective difficult to achieve. First, most investors are not disciplined enough to implement diversification. To illustrate my point, pause and check whether you are willing to reduce equities when the trailing 12-month return on stocks is 20+ percentage points higher than bonds?
