In October 2022, the investment committee of a $12 billion university endowment reviewed its overlay program’s performance. The overlay — a derivatives-based strategy designed to manage risk, rebalance efficiently, and harvest tax losses across the endowment’s 40+ external managers — had a straightforward mandate: reduce volatility and improve after-tax returns.
The numbers told a different story. The overlay had subtracted 180 basis points of value year-to-date. Not because the derivatives misfired, but because the overlay did exactly what it was programmed to do — and what it was programmed to do was wrong for the environment.
The endowment’s CIO described the meeting to a colleague afterward: “We built a machine to keep us disciplined. In 2022, discipline was the problem.”
What overlays are supposed to do
Portfolio overlay management coordinates multiple investment managers within a single portfolio framework. Instead of letting 40 managers each trade independently — generating unnecessary transactions, conflicting positions, and tax inefficiencies — the overlay manager uses derivatives (futures, swaps, options) to adjust overall exposures centrally.
The value proposition has three pillars. First, efficient rebalancing: rather than redeeming from one manager and funding another (triggering taxes and transaction costs), the overlay uses futures to shift exposures synthetically. Second, risk control: the overlay can dial portfolio beta up or down, hedge currency exposure, or implement tactical tilts without disrupting underlying managers. Third, tax management: centralized loss harvesting across the entire portfolio, capturing losses that individual managers — focused on pre-tax returns — would ignore.
The industry has grown substantially. Overlay strategies now manage an estimated $3 trillion in institutional assets globally, according to industry surveys. Major providers include Russell Investments, Parametric Portfolio Associates (a Morgan Stanley affiliate managing over $500 billion), and Overlay Capital. For large institutions with complex multi-manager structures, overlays have become standard infrastructure.
In normal markets, they work beautifully. The problems emerge when markets stop being normal.
How 2022 broke the models
The 2022 bear market was historically unusual: stocks and bonds fell simultaneously. The S&P 500 declined 19.4%. The Bloomberg US Aggregate Bond Index fell 13.0% — its worst year in history. The 60/40 portfolio, the bedrock assumption underlying most overlay programs, experienced its third-worst year in a century.
Overlay programs are typically calibrated on historical correlations. The rebalancing algorithms assumed — based on decades of data — that bond futures would offset equity declines. When both fell together, the overlay’s hedging derivatives amplified rather than dampened losses. A program designed to maintain target allocations through futures kept buying the dip in both asset classes, doubling down on declines that didn’t mean-revert.
The tax-loss harvesting component faced a different problem: there were too many losses. Overlay algorithms are designed to harvest losses selectively, balancing tax benefits against transaction costs and tracking error. In 2022, virtually every position showed a loss. The algorithms, lacking a framework for “harvest everything,” either froze — harvesting nothing while losses evaporated in subsequent rallies — or harvested indiscriminately, generating transaction costs that exceeded the tax benefits.
Currency overlay programs suffered independently. The dollar’s historic surge — the DXY index rose 19% from January to September 2022 — triggered massive hedging activity. Programs designed to hedge 50% of international currency exposure found their hedge ratios whipsawing as central bank interventions and energy price shocks drove unprecedented volatility. Several large pension funds reported currency overlay losses exceeding 100 basis points — not from being wrong about direction, but from the cost of maintaining hedges through violent swings.
The university endowment’s 180 basis points of negative value-add wasn’t an outlier. Industry data suggests the median overlay program detracted 50-120 basis points in 2022, with the worst performers losing over 200. For strategies marketed as risk reducers, this was a reputational catastrophe.
The redesign
The overlay industry didn’t collapse after 2022 — but it changed fundamentally. Three shifts stand out.
First, regime-aware programming. Pre-2022 overlays used static rules calibrated on long-term historical averages. Post-2022 programs increasingly incorporate regime detection — algorithms that identify when historical correlations are breaking down and adjust hedging behavior accordingly. Parametric has been vocal about integrating “correlation stress indicators” that reduce hedge ratios when stock-bond correlations turn positive.
Second, humility about rebalancing. The mechanical discipline that overlays enforce — buy losers, sell winners, maintain targets — is valuable in normal markets but destructive in trending ones. Newer programs include “circuit breakers” that pause automated rebalancing when volatility exceeds thresholds, requiring human CIO approval to continue. The machine still provides discipline, but a human can now override it.
Third, tax-loss harvesting sophistication. The 2022 experience exposed the limits of rules-based harvesting. Leading providers now use optimization frameworks that consider the full distribution of potential outcomes — not just current losses — and that account for the probability of whipsaw reversals. The goal shifted from maximizing harvested losses to maximizing after-tax risk-adjusted returns, a subtly but importantly different objective.
The counterargument: overlays still earned their fees
Defenders of the overlay model argue that 2022, while painful, doesn’t invalidate the concept. Every risk management strategy looks bad in the specific scenario it wasn’t designed for. The question is whether overlays add value across full market cycles, not whether they predicted an unprecedented stock-bond correlation regime.
The long-term data supports this defense — partially. A 2024 study of overlay programs over 15-year periods found average annual value-add of 35-60 basis points after fees, driven primarily by tax management and rebalancing efficiency. The 2022 drawdown, while severe, didn’t erase a decade of accumulated gains for most programs.
But this defense concedes the critical point: overlay value is cyclical, not consistent. The programs add the most value in stable, mean-reverting markets — precisely when investors need them least. In crisis periods, when risk management matters most, the models can fail. That asymmetry should be reflected in how institutions evaluate and pay for overlay services.
The more honest pitch isn’t “we reduce risk.” It’s “we improve efficiency in normal markets and try not to hurt you in abnormal ones.” Few providers market themselves that way, but the sophisticated allocators are starting to demand it.
What the endowment did next
The $12 billion university endowment didn’t terminate its overlay program after the 2022 review. Instead, it renegotiated the mandate: added regime-based circuit breakers, required human approval for rebalancing during high-volatility periods, and shifted the fee structure to include a performance component tied to after-tax value-add.
Three years later, the program has recovered its 2022 losses and then some. But the CIO is candid about the lesson: “We thought we were buying risk management. We were buying operational efficiency with a risk management label. Now we know the difference.”
That distinction — between efficiency and protection — is the real legacy of 2022 for the overlay industry. The programs that survived are better designed, more humble about their limitations, and more honest about what they can and cannot do. The ones that didn’t adapt are gone, acquired by competitors who learned the lesson.
In portfolio management, as in everything else, the most expensive education is experience. The class of 2022 paid tuition. The question is whether the industry learned.
