Systematic Fixed Income by Scott Richardson: A Complete Guide to Bond Investing
Bonds are boring. That’s the general take, right? Stocks get all the attention. Crypto gets all the hype. Bonds just sit there collecting interest like a savings account with extra steps.
Except the global bond market is worth over $100 trillion. That’s trillion with a T. It dwarfs the stock market. And here’s the thing most people don’t realize: the way big institutions manage their bond portfolios is stuck in the past. Most active bond managers still rely on gut feeling and personal judgment to make decisions. In a market that massive, that’s a problem.
Scott Richardson wrote Systematic Fixed Income: An Investor’s Guide to address exactly this gap. And this blog series is going to break the whole book down for you, chapter by chapter.
What Is This Book About?
The short version: how to invest in bonds using data and rules instead of gut feeling.
The slightly longer version: Richardson lays out a complete framework for systematic fixed income investing. That means using models, algorithms, and structured processes to make investment decisions in bond markets. The same approach that has reshaped stock investing over the past few decades but hasn’t really caught on in fixed income yet.
The book covers everything from the big picture (why should bonds be in your portfolio at all?) down to the details (how do you actually pick individual bonds and build a portfolio?). It tackles government bonds, corporate credit, emerging market debt, and the practical challenges of trading in markets that aren’t as liquid as stocks.
If you’ve ever wondered why bond funds underperform, why active bond managers tend to just chase higher yields, or how quant approaches could work in fixed income, this book has answers.
Why Does This Matter?
Here’s something that might surprise you. Most stock investors know about factor investing by now. Buy cheap stocks, buy quality stocks, follow momentum. These ideas have been around for decades and manage hundreds of billions of dollars.
But in fixed income? Most active managers still run things the old way. A portfolio manager looks at the market, forms an opinion, and makes trades based on experience and judgment. Richardson calls these “discretionary” approaches. And he argues they have a real problem: they tend to drift toward reaching for yield.
What does that mean? Bond managers, under pressure to beat their benchmark, often buy riskier bonds that pay higher interest. This feels smart in normal times. You’re earning more income than the benchmark. But it quietly erodes the whole reason you own bonds in the first place, which is diversification from stocks. When the stock market crashes, those risky bonds crash too. Your “safe” allocation turns out to be not so safe.
Systematic approaches can fix this. By prespecifying your investment rules and sticking to them, you can keep bonds doing what they’re supposed to do (providing safety and diversification) while still adding returns through smart security selection.
Who Is Scott Richardson?
Richardson isn’t just another finance professor writing about theory. He’s lived on both sides of the fence.
On the academic side, he’s a professor at London Business School. He earned his PhD from the University of Michigan and was an assistant professor at the University of Pennsylvania. He’s published widely in top journals and won the Notable Contribution to Accounting award in 2009 for his research on earnings quality.
On the practitioner side, he spent years at Barclays Global Investors (BGI, which later became part of BlackRock). At BGI, he was part of what he calls “the original large-scale effort for systematic fixed income investing.” He led their European equity research and global credit research teams. After that, he moved to AQR Capital Management, one of the most well-known quantitative investment firms in the world. There he co-headed the fixed income team and was a senior member of research and portfolio management.
So when Richardson talks about systematic fixed income, he’s speaking from direct experience building and running these strategies at two of the biggest names in quantitative investing. This book actually grew out of an elective course he teaches at London Business School on systematic investing in fixed income.
What Will This Series Cover?
The book has 11 chapters, and we’ll cover each one. Here’s the roadmap:
- Setting the Stage - Key terms, what “systematic” actually means, and bond math basics like yields, duration, and convexity
- Fixed Income: Strategic Asset Allocation - Why bonds belong in your portfolio and how much to allocate
- Fixed Income: Tactical Asset Allocation - When to adjust your bond allocation based on market conditions
- Incumbent Active Fixed Income Managers - How most bond managers operate today and why their approaches fall short
- Security Selection: Rate-Sensitive Assets - Picking government bonds and interest rate strategies using systematic methods
- Security Selection: Credit-Sensitive Assets - Choosing corporate bonds systematically (this one is big enough for two posts)
- Security Selection: Emerging Markets (Hard Currency) - Applying systematic approaches to emerging market debt
- Portfolio Construction Considerations - How to put it all together into an actual portfolio
- Liquidity and Trading Considerations - The practical reality of trading bonds, which is messier than trading stocks
- Sustainability - ESG considerations in fixed income
- Putting It All Together - The complete picture of systematic fixed income investing
Who Is This Series For?
This series is for you if:
- You want to understand bond investing beyond “bonds go up when stocks go down”
- You’re curious about how quant firms like AQR and BlackRock approach fixed income
- You work in finance and want to understand systematic approaches to bonds
- You’re a student or early career professional looking to build fixed income knowledge
- You like data-driven investing and want to see how it applies beyond stocks
You don’t need a finance degree to follow along. Richardson’s book is aimed at institutional investors, but I’ll keep things accessible. Where the material gets technical, I’ll explain the concepts in plain language.
A Quick Note
This is a retelling and review series. I’m breaking down the book’s ideas and sharing my perspective on them. This is not investment advice. Always do your own research and talk to a professional before making investment decisions.
The book itself is dense and rigorous. It’s packed with academic references and real data. I’ll try to capture the key insights without drowning you in equations. But if you’re the type who wants all the details, I’d recommend picking up a copy of the book itself.
Let’s get started.
