What is a Zero Beta Portfolio?
A zero-beta portfolio is a portfolio built with zero systematic risk.
How Does a Zero Beta Portfolio Work?
The investments comprised in a zero-beta portfolio are chosen in such a way that the portfolio's value does not fluctuate as a result of market movements. In other words, a zero-beta portfolio eliminates systematic risk.
Why Does a Zero Beta Portfolio Matter?
The absence of systematic risk in a zero-beta portfolio effectively means that its return is the same as the risk-free rate. For this reason, the return on a zero-beta portfolio is low and, without exposure to market volatility, does not allow it to benefit from potential upswings in the value of the overall market.
