Global growth spurs convertible bonds opportunities, strong issuance may be ahead
• Convertible bonds have outperformed equities and bonds over the long term • NN IP anticipates two economic scenarios in which interest rates will increase and economic growth will either remain range-bound or break out on the upside, supporting the case for convertible bonds. • NN Investment Partners (NN IP) expects monetary tightening and higher bond yields to prompt greater issuance of convertible bonds
Convertible bonds (CBs) have generated equity-like returns with much lower volatility over the long term, reveals analysis by NN Investment Partners (NN IP). The analysis underlines that over the 20 years until March-2018, CBs have outperformed equities, global corporate bonds and global government bonds.
NN IP anticipates two possible economic scenarios in which interest rates will increase and economic growth will either remain range-bound or break out on the upside. Jasper van Ingen, Senior Portfolio Manager at NN Investment Partners explains below why CBs offer outstanding tactical investment opportunities in both scenarios.
Van Ingen expects monetary tightening and higher bond yields will prompt greater issuance of convertible bonds. He comments: “CBs have generated equity-like returns with much lower volatility over the long term, making them an attractive addition to many investors’ portfolios. As we look ahead, rising rates and bond yields are likely to incentivise companies to issue CBs as a means of saving on interest expenses, improving market dynamics and widening the pool of investment opportunities.”
Asymmetric return profile
An important feature of CBs is their asymmetric return structure: they capture equity upside while protecting against the downside. Over the economic cycle, CBs capture 30-60% of the performance of their underlying equities. This asymmetry generates a positive relationship with volatility. Van Ingen says: “The asymmetric return profile means that all else being equal, a CB benefits more from an increase in the underlying share price than it loses from a decline of similar magnitude. This attractive characteristic means that higher stock volatility is good for CBs.”
High credit quality, low default rate
CBs present an attractive risk profile, with the average credit quality of the balanced CB universe currently at BBB-. In times of stress, the default rate of the CB universe is much lower than that of high yield bonds. For example, in the 2008 financial crisis, the CB default rate peaked at less than 3%.
Correlation and diversification
Like equities, CBs have a negative correlation to government bond returns (-11% over the past 20 years), while the correlation between CB and equity returns is high (87%), providing protection for investors during times of increasing Treasury yields. Indeed, CBs showed strong positive return during the last significant rise in Treasury yields - the “taper tantrum” of May-September 2013 - when five-year Treasury yields increased from 0.71% to 1.60%.
CBs’ limited correlation to other traditional asset classes makes them a valuable diversifier, increasing a portfolio’s expected risk-adjusted return.
Gains from M&A and other corporate activity
CBs typically have in-built protections that allow investors to benefit in the event of corporate takeovers. Investors can be rewarded both through an increased share price following a transaction and through change-of-control protection features often built into them.
Van Ingen concludes: “We believe CB’s represent an interesting investment opportunity going into 2018 and beyond. The asset class combines several characteristics that may prove very valuable: a low effective duration, moderate correlation to other asset classes and participation to equity markets that are supported by growth expectations”.
