A Tour of the Signature Short-Term Bond Fund

Paul Borean's picture

Throughout the era of highly accommodative monetary policy that has endured over much of the last decade, a core fixed income solution is still viewed by many investors as the key source of diversification for portfolio risky-asset exposures. This preference has held even during a regime where bonds’ correlations with risky assets have not always behaved as one would expect.

The implication in practice is that when typically negative Canadian bond and equity return correlations do not apply, as they have at points within the last few years (see plot below), the degree of interest rate sensitivity of portfolio fixed income holdings becomes a point of concern. Fixed income allocations cease to provide the intended portfolio insurance if interest rates across the curve are rising alongside a sell-off in equity markets.

Short-term fixed income portfolios can be beneficial for filling this niche, reducing the return hit to portfolio fixed income holdings during periods when interest rates are rising across the curve, while still providing some risky-asset diversification benefits when equity market returns soften and typical negative return correlations hold.

In the following, we briefly highlight some further compositional differences between short-term and broad fixed income exposure in the Canadian context, and discuss Signature’s approach to short-term fixed income investing, including recent performance and positioning.

Different from broad fixed income exposure

There is a wide gap in the overall interest rate sensitivity of short-term bonds relative to the broader Canadian fixed income market, represented here by the FTSE/TMX Canada Short-Term Bond Index (“Short-Term Index”) and FTSE/TMX Canada Universe Bond Index (“Universe”) respectively. The duration of the Short-Term Index is just over one-third of that of the Universe, making its returns less exposed by approximately this amount to a given shift higher in the level of interest rates. In addition, the Short-Term Index exposure is limited to issues ranging from 1 to 5 years to maturity, while the Universe spans the whole maturity spectrum from 1 year onwards, entailing different interest rate volatility exposures, which can vary materially at the various points across the yield curve.

Beyond the raw interest rate risk, there are also noticeable divergences in credit composition between the two market segments. More specifically, the Short-Term Index exhibits a sort of barbell in issuer content compared to the Universe, carrying a larger presence of federal and corporate paper and a much lesser quantity of provincial debt (see bottom plot above), partly reflecting the preferred habitat of the issuance programs of these various bond issuers. The quality of the corporate credit in the Short-Term Index also displays a notable tilt toward higher-rated names, with some 10 percentage points less BBB-rated paper compared to the Universe (see the two plots below).

Given these variations in the beta exposures between short-term and broad fixed income markets, actively managing shorter-term fixed income portfolios requires a different approach.

Short-Term Bond Portfolio Positioning at Signature

In the interest of maintaining diversified exposure within the Signature Short-Term Bond Fund (see our blog titled “Portable beta in modern fixed income design” for more about this framework), we have spent much of the year carrying exposure across the US term structure, with these positions being reallocated primarily from 5-year maturity Canadian bonds. Our US investments include USD investment-grade emerging-market sovereign debt, agency mortgages and inflation-linked bonds, and we retain positions in such issues today. Although some of these US assets range beyond the typical 5-year longest maturity of instruments in our benchmark, we have managed this exposure to be mindful of the balance of risks around taking positions in longer-dated US bonds relative to shorter-term Canadian bonds, as well as any credit risk and residual currency exposure, after accounting for hedges in the latter.

Our inflation-linked bond positions were scaled back during the first nine months of the year, in part to limit exposure to their underperformance relative to US nominal benchmark bonds, but also to take advantage of the outperformance of US duration relative to the Canadian market. In addition, once much of the adjustment higher in Canadian yields prompted by the Bank of Canada had taken place, we took Canadian duration moderately higher mainly via purchases in 5-year maturities. This added duration also helps provide some insurance against a potential softening in credit-risky assets, which have performed admirably relative to Canadian government benchmark bonds year-to-date.

Heading into the final month of the year, the short-term bond portfolio has shifted duration close to its benchmark, though the portfolio remains short in the 3- to 5-year area of the Canadian yield curve. Within the spread product arena, in addition to the US asset positions highlighted above, we remain overweight corporate and provincial credit and underweight Canadian government agency debt.

Appendix: Signature Short-Term Bond Fund Performance Analysis

The Signature Short-Term Bond Fund advanced by 1.34% year-to-date as of November 30, 2017, outperforming the FTSE/TMX Canada Short-Term Bond Index (the portfolio benchmark) by 0.81%. The total return outcome of the portfolio was primarily driven by the net compression of corporate credit spreads, and to a lesser degree government credit spreads, with a modest offset coming from the rise in Canadian interest rates.

On a relative-to-benchmark basis, duration and yield curve positioning was a key contributor to portfolio alpha, benefitting from an underweight duration position in 5-year maturity Canadian bonds, both outright and relative to the US, amid a hawkish shift from the Bank of Canada during the second quarter and two rate hikes being delivered in the third quarter. In the spread product arena, overweight positions in corporate credit, US agency mortgages and emerging market spreads were all beneficial for alpha, with corporate credit registering the largest alpha contribution. Please refer to the table below for a detailed breakdown of the performance.
