Write on the money

Back in June 2023, we provided an overview of BuyWrite strategies, and since then, investor demand has surged significantly – to-date, assets managed under the iShares fixed income BuyWrite range has expanded from USD 60mn to USD 2,196mn. With income remaining a key theme in fixed income investing, we take a closer look at how BuyWrite ETFs can effectively enhance income during periods of elevated market volatility.

Recap

BuyWrite strategies combine a long position on the underlying security and a short call option. Thus, the investor sacrifices the upside of the underlying but is compensated, to an extent, by option premiums.

Volatility as opportunity

Covered call ETFs are a valuable tool for investors seeking a differentiated source of income. However, while the investor receives consistent option premiums, the upside is capped as the calls are typically written with strike price targets of 100%-102%. This trade-off makes BuyWrite strategies more defensive, prioritizing income over capital appreciation.

As yields broadly retraced and spreads remain tight amid the Fed’s easing cycle, investors who are underweight long-end fixed income due to higher demand for term premium or seeking additional income – can consider BuyWrite strategies, where consistent option premiums can help reduce overall portfolio volatility. While bond market implied volatility has stabilized in the post-COVID era, risks for volatility spikes and rangebound rate environments create opportunities for investors to capitalize on volatility through BuyWrite strategies.

BuyWrite strategies generally outperform in stable markets or during market downturns
