One of the most important elements of our systematic strategies is our collaboration with Barclays Quantitative Portfolio Strategy (QPS), a group that has long been recognized as one of the leaders in quantitative portfolio research. Each day, Barclays QPS provides us with a custom systematic strategy index that reflects individual signal scores for three style factors for each bond in a specified index. We use a combined score of the three signals to rank index constituents. Our process seeks to maximize exposure to high scoring bonds.
In this post, we discuss our goals for the construction of portfolios and the choices behind the signals used.
We designed our portfolio construction process to aim for the following goals:
As a bottom line, we want to be consistent with the “client-first” mindset that drives our team’s decision making. We need to make sure that the systematic portfolios are generating alpha, are in line with client objectives and are measured against an appropriate benchmark.
The first systematic strategies coming out of our collaboration with QPS are focused on investment grade corporate credit where strategies are based on signals related to three factors: Value, Momentum and Sentiment.

To implement our systematic portfolios, we use the combined signal score of each individual bond in the universe in a portfolio optimization process. An important part of this process is that we incorporate risk controls to ensure that the portfolio risk profile remains aligned with the target benchmark index. Daily, we review the duration-times-spread (DTS), the duration, the sector weightings, the ratings, and the issuer concentration of our systematic portfolio versus the target benchmark index, and make sure that the portfolio remains within specified ranges of the benchmark on those parameters.
Furthermore, we want to focus portfolio rebalancing on those bonds that are more liquid and more likely to be easily traded. To identify these bonds, we consider the Trade Efficiency Score (TES), which combines recently realized turnover with estimated transaction costs. Then, we control portfolio turnover, as excessive turnover can come with elevated transaction costs and can be detrimental to net performance.
We are cognizant of transaction costs and the negative impacts they can have on portfolio outcomes. Our analysis aims at striking the right balance between actively seeking opportunities in high score securities while avoiding excessive transaction costs.
By incorporating risk and liquidity constraints, we aim to construct portfolios that maximize the combined signal scores while controlling turnover and keeping risk parameters close to the target benchmark index (Figure 1).

Optimized Portfolio Structure Maximizes Risk-constrained Exposure to Style Factors
Through our collaboration with Barclays QPS, we can use robust algorithmic signals to identify securities that are most beneficial for constructing systematic portfolios. However, transparency and pricing need to be considered as well. Fixed income markets are broad and fragmented, and even though the asset class has made great strides in trading efficiencies, illiquidity remains a concern for certain issuers and issues.
Our capabilities as an index manager allow us to efficiently build portfolios that maximize portfolio signal scores, limit risk exposure relative to the benchmark, and control turnover and transaction costs. We combine the Barclays QPS data excellence with our practical portfolio sampling and implementation experience.
