Barbell-Shaped Portfolio Definition

A Barbell-Shaped Portfolio is an investment strategy in which half of a fixed-income portfolio contains long-term bonds while the other half is made up of short-term bonds.

This type of investment strategy weighs heavily at both sides, the strategy looks like a barbell which is why is it called a barbell-shaped portfolio.

A barbell shaped portfolio is a combination of high-risks and low-risk assets in a bid to get a better yield.

Portfolios in which the barbell is being increasingly used include; stock portfolios and asset allocation, low-beta sectors/assets, high-beta sectors/assets and others.

A Little More on What is a Barbell – Shaped Investment Portfolio

When barbell is used as an investment strategy, a fixed-income portfolio would have both short-term bonds and long-term bonds and no other bonds between them. Frequent monitoring is required on the part of a portfolio manager that implements a barbell portfolio. Since this strategy is that that combines assets with high risks and those with low risks in order to get maximum return, monitoring is needed.

Usually, a barbell portfolio contains 50% safe investments and 50% high-risk investments. However, the weightings of both halves of the portfolio are not fixed at 50%. That is, in barbell portfolios, the weightings can be adjusted based on market conditions.

There are many reasons barbell investments or portfolios are attractive to investors. Investors using barbell techniques reduce investment risks and at the same time have to potential to obtain higher returns. For instance, in cases of increase in the interest rates of short-term bonds, the yield of the bonds can be reinvest or used to purchase additional bonds to maximize profit. The short-term bonds in the investment portfolio have short maturity period, thereby providing liquidity for investors.

Despite the benefits of barbell portfolios, its drawback is that it makes no room for middle or intermediate-term bonds. This might not be ideal, especially in cases of economic boom where medium or intermediate-risk bonds have outstanding market returns.
