Systematic High Quality Corporate Fixed Income: Q1 2026 commentary
- Markets were dominated by geopolitical shocks that disrupted energy markets and raised volatility levels; despite a late-quarter reversal, markets largely absorbed the deteriorating newsflow.
- Our SAFI strategies continued to perform well, delivering consistent alpha in the latest quarter, driven by complementary factor behavior—notably in value and momentum.
- Higher volatility contributed to increased dispersion in factor scores, helping to expand the opportunity set; systematic, continuous rebalancing helped capture those opportunities.
Amid elevated uncertainty, follow the alpha signals for strong, consistent investment outcomes
Geopolitical tensions were at the heart of the market narrative in Q1 2026. From the US capture of Venezuelan President Nicolas Maduro in early January to the US-Israel strikes on Iran in late February that sparked retaliation, the impact on global energy markets in particular has been immense. For broader financial indexes, the returns for Q1 suggest that investors had largely taken the deteriorating backdrop in stride, although the reversal in March was not insignificant. As is always the case during periods of uncertainty, we remain disciplined in our Systematic Active Fixed Income (SAFI) approach, relying on our time-tested value, momentum, and sentiment signals to guide security selection. The performance of our strategies in the latest quarter is reflected in Figure 1.

From SAFI inception in December 2023 through March 2026, our Systematic US High Quality Corporate strategies delivered alpha and risk outcomes that, in many instances, ranked near the top of the US active credit manager eVestment universes, gross of management fees.

Factor alignment and high dispersion drove strong performance
Evaluating SAFI results requires understanding how factors behave, when they tend to work (or not), and how they interact. Value is typically the main source of outperformance in most environments. Momentum plays less of a role in driving performance when spreads are rangebound, but this factor tends to be most powerful during periods of credit weakness.
Figure 3a shows value and momentum factor performance since SAFI inception.1 Over this period, we have experienced three notable episodes of credit weakening: Yen carry trade unwind in August 2024, Liberation Day in April 2025, and the Iran War in March 2026. In contrast to many active peers, our SAFI portfolios generated consistent outperformance (or effectively limited downside risk) through each of these environments, as highlighted in Figure 3b.

Figure 4a also highlights that factor behavior is often complementary, with value and momentum frequently offsetting each other – an important contributor to the consistency of SAFI’s alpha generation across regimes. In March, the market environment was constructive for SAFI because value and momentum were aligned and positive. In February, spread widening created value opportunities. At the same time, momentum2 tilted our portfolios towards attractive issuers/sectors that performed well and underweighted those that did not.
Having tightened to new multi-decade lows of 70 basis points (bps) in January, US investment grade corporate spreads widened to over 90 bps by the end of the quarter, while Treasury yields rose sharply as inflation concerns intensified against the backdrop of surging energy prices. Despite these moves, our SAFI strategies generated strong and consistent outperformance, underpinned by diversified factor contributions and attractive drawdown characteristics. In March, SAFI HQ Long delivered 35 bps of alpha, including 9 bps from value and 9 bps from momentum.

Dispersion created opportunity, systematic rebalancing captured it
The rise in market volatility created the high dispersion in factor scores, particularly in March, creating broad scope to improve portfolio factor scores through efficient day-to-day turnover. Capturing the opportunities requires disciplined, systematic rebalancing.
Security-level attribution in March supports this: the distribution of factor contributions by ticker in the long strategy was right-skewed (Figure 5). Of the 344 tickers that were in either the long portfolio or its benchmark, 225 provided positive contributions, adding 42.5 bps, while 119 detracted, subtracting 23.6 bps. This efficacy across a broad range of market environments, including credit drawdowns, is exactly what we target in our SAFI portfolios.
Maintain objectivity and agility through volatility via alpha signals
The SAFI process keeps the portfolio systematically allocated to bonds that are most attractive based on empirically supported alpha signals. By maintaining continuous, efficient exposure to these factors, we have a strong belief the strategies can outperform and support clients’ objectives over the long run. Importantly, even in periods of high uncertainty and volatility, the signals help us reposition nimbly and objectively—without relying on discretionary reactions to headlines.
