Diversification means not placing all of your exposure in one place. It is a familiar idea, but it is often misunderstood as a way of avoiding loss. It is better understood as a way of avoiding a single point of failure.
What diversification does
When holdings behave differently from one another, a setback in one can be offset in part by steadier results elsewhere. This tends to reduce the swings in the overall picture without removing risk altogether.
What it cannot do
Diversification does not guarantee a profit or protect against loss, and in broad downturns many holdings can fall together. It also does not substitute for understanding what you own and why.
The same idea in business decisions
Organizations face concentration risk too: one customer, one supplier, one market, one key person. The project risk register we describe elsewhere is a practical way to surface these concentrations before they become problems.
Public education resources from the SEC's Investor.gov explain asset allocation and diversification in neutral terms and are a good place to begin.
