Has the time come to adopt a more defensive approach to high yield? The structure, breadth and complexity of the high yield market make it a challenging environment for investors. But it also offers attractive returns compared to other credit segments and high yield bonds receive a fixed allocation in many portfolios. As timing the peak of the market is notoriously difficult, what are the options for managing the high yield allocation in the later phases of the credit cycle?
Robeco Dynamic High Yield offers a solution to this quandary. This is a strategy that enables investors to maintain high yield exposure, while outsourcing the ‘timing decision’. It does this by reducing risk when spreads are expected to widen and the high yield market looks bearish, or by increasing exposure if spreads look set to tighten and prices to move higher.
Decisions on when to dynamically adjust exposure are fully based on the signal from a proprietary quantitative market-timing model, which is rooted in academic research. The model applies various fundamental, well-established and technical variables to forecast credit returns, including macro factors and equity market trends.
By systematically adjusting the investment portfolio according to the model’s signals, the strategy avoids well-known human behavioral biases and can even benefit from them. When markets are driven by investors’ emotions, the model sticks to the fundamentals.
The high yield corporate bond market lacks the liquidity of the equity or developed government bond markets, so it can be difficult for investors to move in and out of it rapidly. As this strategy focuses on market timing, it requires this flexibility and thus uses credit default swaps (CDS) to gain high yield exposure rather than buying individual high yield bonds.
Investing in a CDS index means buying one single market instrument to gain a broad high yield exposure. No bottom-up issuer selection is required, differentiating this approach from traditional fundamental high yield approaches. The CDS indices the strategy uses are well-established, cover a representative range of issues and are regularly rebalanced, thus ensuring their quality in terms of liquidity and diversification. Trading these indices instead of individual bond issues offers flexibility in terms of trading volume and enables portfolio changes to be implemented quickly while keeping transaction costs down.
‘A liquid high yield solution that dynamically allocates market exposure’
At times of market turmoil, when high yield bond returns can be hit severely, the impact on these more liquid instruments is less extreme and drawdowns are historically less severe. While the lower liquidity of cash bonds increases risk, this is not rewarded with higher returns. So in this respect, CDS indices are able to deliver more stable returns over time and offer a better risk-return ratio than the global high yield bond index.
As the chart below illustrates, the Dynamic High Yield strategy’s performance somewhat lags that of the high yield bond market in bull markets. But its strength lies in the combination of the timing element and the CDS exposure and the protection this offers in bear markets; a factor which can be particularly significant in a volatile segment like high yield.
In bear markets, including the market corrections of 2002, 2008 and 2015, the cash high yield bond market suffered more acutely than the CDS indices. For example, in 2008, when the market plummeted, falling around 29%, the losses incurred by the more liquid CDS indices were much smaller and the strategy lost only 2.1%. Although high yield bonds recovered more strongly, as is reflected in their higher return in bull markets, both the CDS indices and the strategy posted higher returns over the period as a whole.
As a quant high yield approach, Robeco’s Dynamic High Yield strategy can function as a style diversifier. For example, it offers investors in traditional high yield strategies an alternative way of gaining high yield exposure. It is also suitable for tactical investors as it offers the flexibility to make short-term decisions and more effectively time high yield exposure.
But in the current market environment, the most compelling argument for this strategy lies in its ability to offer high yield exposure in a more defensive way. It is a solution that combines less risk, lower costs and more stable returns. It has outperformed in bear markets and addresses the liquidity concerns sometimes associated with weaker high yield markets. These attributes result in a superior risk return profile and a higher Sharpe ratio over the credit cycle as a whole.
