Convertible bonds: a low governance equity hedge
Uncertain times call for resilient portfolios, particularly for pension schemes and insurers holding equities.
Equity holdings are exposed to the current uncertain environment as global markets are buffeted by geopolitical risk, including the US-China trade war. This has led to volatility in stock indices globally, amid some correction from the very highs hit in early 2019.
Convertible bonds could provide a flexible solution to address some of the equity drawdown issues facing pension schemes and insurers.
Convertibles are corporate bonds with an embedded equity call option. This hybrid structure means that convertible bondholders tend to be less exposed to falls in share prices than a customary equity holder because the bond element enables them to effectively dampen the equity downturn.
Strategically, convertible bonds have provided attractive risk-adjusted return characteristics compared to traditional equity allocations1.
Convertibles could also be a powerful alternative to equity options, in our view. Firstly, investing in convertibles requires a less onerous governance framework than that required for equity options. Secondly, convertibles have, on average in the past, provided better protection against volatility than some equity option strategies2.
Investors could use convertibles to temper the exposure of their equity allocation to volatility by rebalancing part of the equity allocation away from equities and towards convertibles. Reducing the equity allocation by 30% and replacing this with convertibles has historically protected a portfolio during drawdowns by approximately 20%3.
It is important to tailor the convertible bond mandate to suit specific investor needs, and to optimise the distinctive features of the asset class.
We believe that convertible bonds offer compelling arguments to mitigate exposure to volatility, both in terms of the asset class’s higher Sharpe ratios and its lower governance features compared to equity options.
