The Paper Trail: Academic Alpha

The lunches are packed, the pencils are sharpened, and kids everywhere are mourning the unofficial end of summer. Back-to-school season has arrived.

Speaking of which, investing has always had an interesting relationship with academia. Many of the ideas we now take for granted started as academic research, while others have been debated, refined, challenged, and occasionally discarded as they collided with the real world. That tension between theory and practice is part of what makes investment research so interesting in the first place.

So the timing was fitting when AQR published a paper this month titled Academic Alpha, which revisits investment ideas grounded in decades of academic research and asks whether well-documented sources of return can still add value once they are widely known by market participants.

From there, August’s curriculum ranges from the virtues of doing nothing to the dangers of zombies in private equity, with detours through direct lending, secondaries, prediction markets, hybrid capital, real estate, electricity demand, and even outer space.

Class is now in session!

Can an investment strategy still generate alpha if everyone knows about it?

"The most valuable academic alpha signals have a demonstrated ability to deliver returns even when they are well-documented and well-known to market participants. How? Because each has a persistent ‘other side.’"

Can investors combine downside protection with equity-like upside in the same private market investment?

"The floor may reduce the severity of a bad outcome, while the participation component may prevent the investment from being capped at a lending return when things go right. That is why hybrid capital is not simply ‘higher-yielding credit’ or ‘safer private equity.’"

What will private equity need to do differently to earn its historical returns?

"Said differently, the old levers have not disappeared. We believe private equity should still focus on maintaining EBITDA multiples, using leverage effectively, and driving double-digit growth. But reliance on those drivers alone may not be a sufficient path to historical returns."

Is market concentration a flaw, or simply what successful compounding looks like?

"These two principles point in different directions on the question of concentration. Breadth of inclusion argues for holding many names. Restraint in trimming argues for allowing some of those names to become large. A portfolio that follows both will hold a wide cross-section and will let its winners grow, which produces concentration as a result rather than as a deliberate choice."

Where will direct lending find its next leg of growth?

"Direct lending still has a long adoption curve ahead. In mature markets such as the U.S., the opportunity set continues to broaden beyond sponsor-backed lending into founder, family and management-owned businesses while in Europe and Australia, the runway is longer still, as more companies become familiar with non-bank capital."

Should portfolios be organized by asset classes or around the economic exposures investors actually want?

"The framework is not about reducing the differences between public and private markets; it is about using those differences more intentionally, and starting portfolio construction with why an investment belongs rather than where."

Is AI really the biggest driver of the coming electricity boom?

"In fact, data centers (AI and non-AI combined) are expected to drive less than 10% of global electricity demand growth over the next few years. In Europe, EVs are expected to be bigger drivers of electricity demand than data centers, and emerging market demand revolves more around economic development and infrastructure expansion."

What changed to make space a commercially viable industry?

"In 1981, getting a kilogram of mass into LEO cost $65,400/kg on the US Space Shuttle. Today, SpaceX Falcon Heavy has brought costs down to $1,500/kg."

Has private real estate finally repriced enough to create attractive entry points?

"Conversely, assets in the transaction market seem to be trading at higher cap rates than those within the index. As seen in Exhibit 3, assets in the transaction market have been repriced to more favorable levels and seem to provide a healthier risk premium over the 10-year Treasury yield."

Can prediction markets be smart when most of their participants lose money?

"The profits in prediction markets tend to accrue to a small percentage of participants. One study that included nearly 600 million trades on Polymarket from November 2022 through March 2026 showed that among users with gains, the top 1 percent captured 77 percent of the profits and the top 10 percent gathered 96 percent. Of the 2.4 million users overall, 69 percent lost money."

Should listed REITs and private real estate really be treated as separate asset classes?

"Listed and private real estate are ultimately anchored by the same underlying property cash flows, but they are priced differently. Private real estate valuations typically adjust gradually through appraisal-based processes, while listed REITs reprice continuously in public markets."

Why are investors paying more for the most concentrated secondary deals?

"Despite par-to-premium pricing and the inherent concentration of SACVs, buyers are underwriting them to higher, not lower, returns. Target multiples average ~2.3x for SACVs, against ~1.9x for MACVs, ~1.8x for single LP Interests and ~1.7x for diversified LP portfolios."

How big is private equity's aging asset problem?

"Although exits have begun to recover modestly, the industry is now contending with a sizable backlog of aging assets—many held for five years or longer, and some well beyond their typical holding periods—with no clear path to an attractive exit."

Private Equity's Zombie Problem (PitchBook)

Who is going to pay for the AI buildout?

"No single financing market will be large enough to meet these needs. The financing mix will depend on market conditions, rating considerations, asset type (e.g., GPUs, data centers) and the willingness of hyperscalers and chipmakers to provide contractual support to data center developers and other ecosystem participants."

What happens if investors simply buy stocks and never sell them?

"While history may indeed have included cases where, for example, an individual purchase of three shares of stock for $180 grew to a value of $7 million seventy five years later, the much more frequent cases where narrow portfolios underperform rarely lead to dedicated Wikipedia pages."
