The Replication Crisis That Wasn’t

March 24, 2021 - Cliff Asness

Factor investing has long faced criticisms of data mining, and more recently faced another criticism – some backtests might never have been right to begin with. A growing body of mostly well-done papers examine these issues, generally concluding that factors have been disappointing since their “discovery.” We’ve long addressed these concerns through robust out-of-sample evidence and a compelling theory for why a factor should work. What we’ve lacked, until now, is a formal test. My colleagues’ new paper tests brilliantly, what we have argued, largely anecdotally, for years. Their results are rather startlingly (even to me) positive for the field in general.

The Long Run Is Lying to You

March 4, 2021 - Cliff Asness

Everyone knows the value strategy has been a grave disappointment out-of-sample since, say, 1990, based on realized returns. However, odd as it might sound, the realized average return on a strategy is not necessarily the best estimate of its true long-term expected return. In fact, the right estimate of the true long-term expected return of the value strategy is considerably higher than many might think if they were to just look at simple past returns – especially right now. Why? I explain it in this note (spoiler: it has to do with changes in valuation).

Now There's Nothing Certain But Death

January 15, 2021 - Cliff Asness

Over the last few years, we’ve built a considerable effort in tax-optimized investing. Admittedly, this was a little bit of a “if we build it, they will come” venture, given many taxable investors seem to ignore after-tax returns. Thus, it is gratifying to see my AQR colleagues win the Top Graham and Dodd Award for their research on tax optimization, a topic that I’ve long thought deserved a much more prominent place in asset management.

A Gut Punch

December 22, 2020 - Cliff Asness

Sure, the last nearly three years have hurt, but at least the explanation was straightforward. A core part of our process, value, suffered. So when value rebounds, we will too, right? Well, not necessarily. To be clear, if value makes a prolonged major recovery, we certainly believe we will as well, but over short periods that doesn’t have to happen. Unfortunately, this is what we have experienced since the end of October. Regardless, it does not change my view one drop that going forward multi-factor investing is a darn good bet in a world that needs some darn good bets.

There Is No Size Effect: Daily Edition

September 18, 2020 - Cliff Asness

We have written several pieces on the famous small-firm or size effect, the two most important being our study of the interaction of size and quality and a fairly comprehensive survey of all things size. This note focuses on daily instead of the longer-horizon data studied in these other papers and, while not changing the overall story, this leads to a powerful illustration of what’s going on in small stocks.

The Valuesburg Address

February 27, 2020 - Cliff Asness

One score and eight years ago Fama and French brought forth on this world, a new factor, conceived in either risk or behavioral effects, and dedicated to the proposition that all portfolios are not created equal. Now we are engaged in a great drawdown, testing whether investors in that factor, or any factor so conceived and so dedicated, can long endure…

Sic Transit Gloria Mundi

February 25, 2020 - Cliff Asness

To quote Kipling, it’s crucial to “meet with Triumph and Disaster and treat those two imposters just the same.” Cliff explains that throughout the good and bad times, we’ve stressed that long-term investment success is about sticking with real but modest edges.

Never Has a Venial Sin Been Punished This Quickly and Violently!

February 19, 2020 - Cliff Asness

Three months ago in “It’s Time for a Venial Value-Timing Sin,” Cliff demonstrated the value factor’s historic cheapness, suggesting it’s time to “sin a little” and modestly overweight value. While portfolio tilts are seldom promptly rewarded, it’s also rare they are instantly punished. In this piece, Cliff shows how 2020 has been the exception to the rule, as value has begun this year with its worst loss in its decade-long drawdown.

The Illiquidity Discount?

December 19, 2019 - Cliff Asness

Conventional wisdom is you get an expected return premium for bearing illiquidity. But what if this is backwards? What if investors will actually pay a higher price and accept a lower expected return for very illiquid assets?

It’s Time for a Venial Value-Timing Sin

November 7, 2019 - Cliff Asness

Cliff discusses how to measure whether a factor, in this case the value factor, is itself rich or cheap versus history. The answer, regardless of the approach taken in measuring cheapness, is that value is currently quite cheap compared to history.
