Spurred by groundbreaking insights on systematic investing from its Nobel Prize-winning advisor Eugene Fama, Dimensional Fund Advisors has been extending duration in its core bond portfolios this year.
Fama-inspired research spanning decades of market history over thousands of securities shows longer-dated bonds have plenty to offer now that forward rates are on the march. Thank the combination of a steepening U.S. yield curve and the rising compensation for holding long-term Treasurys, or the term premium.
All that is spurring the allocation models that guide David Booth-founded Dimensional to flash buy signals across the asset class.
The Austin, Texas-based manager’s conviction adds to the Wall Street divide over the world’s biggest bond market as inflation breaks out and debt burdens swell.
“Rising interest rates do not automatically imply a negative return for a bond,” said Dave Plecha, the global head of fixed income at Dimensional, which has some $650 billion in assets overall. “We develop portfolios with higher expected returns than the benchmark and over the years we’ve delivered on that.”
Treasurys have taken big hit this year thanks to a sharper-than-expected economic rebound spurred by the rollout of vaccines for COVID-19. While Federal Reserve officials insist inflation will prove
That’s prompted the likes of Bridgewater Associates founder Dalio to lambaste the safety of Treasurys and tout the hedging potential of Bitcoin as an alternative, with onetime debt king Bill Gross also among
But finance legend and Dimensional consultant Fama isn’t buying it.
“Companies and governments are issuing tons of debt and they’re all getting snapped up,” said the professor at the University of Chicago Booth School of Business in an interview. “Investors are still buying a lot of bonds.”
While the selloff in U.S. government debt has retreated this quarter, the yield curve, as measured by the gap between two- and 10-year yields, remains near the steepest in over five years. The 10-year term premium — the compensation for the risk of holding longer-dated U.S. debt over rolling shorter-maturity securities — turned positive in February for the first time since 2018.
These moves have increased forward rates, or the expected returns derived from current yields and the interest-rate curve. To Dimensional, that’s a sure-fire signal that longer-dated bonds today offer richer rewards.
As a result the firm is running higher interest-rate risk, or duration, than the benchmarks in its core strategy allocations.
Despite long-term outperformance, many of the leading 20 have suffered short-term losses.
This includes the some $13 billion DFA Investment Grade Portfolio, which has beaten 80% of its peers over the past three years with an annual return of 6.19%, though it’s underperformed over the past year, according to Bloomberg data. The $6.6 billion DFA Inflation-Protected Securities Portfolio has surpassed 90% of peers with an annual return of 7.08% over the past three.
Dimensional’s approach differs from discretionary investors who like to dissect an issuer’s business and model the monetary cycle, and also other fixed-income quants that
In stocks, Dimensional has never wavered from its faith in the value strategy, which the firm helped bring to the masses through its network of
Pretty premiums
Looking at past prices as an allocation guide may be beside the point if Wall Street bears are right that Treasurys are in uncharted territory. A surge in inflation could dramatically erode the value of future bond payments, severely undermining potential future returns.
But to Plecha in Santa Monica, California, sticking to tried-and-tested rules over the long haul is preferable to trading on unknowable existential bets.
“Fama’s work shows that, on average, when yield curves are upwardly sloped, you can expect larger premiums for moving out the curve,” he said. “That tells us to go out and extend duration and collect them.”
