  1. It seems that now everyone wants to time factors. Indeed, we’d love to as well if we thought it was a very useful endeavor. But, although tempting, in an editorial piece for a special upcoming Journal of Portfolio Management issue focused on quantitative investing — written at the kind request of long-time editor, Frank Fabozzi — I argue that this tempting siren song should be resisted, even if I know some will be disappointed with this view.

  2. If you’re still hawking the story that the original results of Fama and French, Jegadeesh and Titman, Lakonishok, Vishny and Shleifer — and even yours truly and others — were the result of data mining, you have been completely defeated on the field of financial battle, and you must stop.

  3. Miles Johnson of the FT takes strong issue with an article I didn’t write but, rather, one he thinks someone like me would write (I’m sorry if that’s hard to follow but it’s Miles’s fault).

    I wrote a fairly narrow piece pointing out that articles marveling at the 2015 compensation of the top 25 hedge fund managers (e.g., here or here) are about wealth when they purport to be about income. That’s basically it.  Not a statement that wealth wasn’t important.  Not a defense of this wealth.  Ayn Rand didn’t leave the building as she never entered it.  I mentioned that this “mistake” likely occurs as higher numbers sell more papers (or whatever people buy or read for free these days) than do lower numbers. I made a point of saying that this is not about the inequality debate, rather, it’s just about exaggeration and imprecision. That was it. 

    In fact, in the email I sent when recirculating this article I wrote a year ago (sorry you missed it the first time Miles) I specifically said and meant, “There’s plenty to debate on the investing merits and the inequality issues here without simply bad, and intentionally misleading, math.” 

    Nowhere in my original piece, or anywhere else, is my obtuse denial of these important issues actually detectable. Nowhere did I say that wealth wasn’t an important part of the debate.  Nowhere did I defend the hedge fund business model (quite the opposite, more on that below).  I pointed out, literally just this — that wealth is not income, and that these now annual articles confuse this, probably intentionally. I stand by that as fact. 

    Actually, I have written a lot criticizing hedge funds and I’ve done it for a long time. My firm isn’t really a hedge fund by fees or majority of assets, but that is apparently too subtle for Miles (or inconveniently didn’t fit his slant) as labels are so much easier.  I actually say as a matter of disclosure here that my firm has likely benefited from the move to lower fees and truly hedged products and away from the traditional hedge fund model and that I have a long history of criticizing overpriced and under-hedged hedge funds.  In the age of Google it would not take an incredible effort of journalistic research to note my analysis and commentary going back to 2001 in hereherehere, or maybe here?   I got yelled at by many in the hedge fund industry for it (especially the first one when I was younger and would actually listen to semi-famous people yelling at me on the phone!).  The hedgies didn’t want balance and accurate analysis back then any more than Miles does now.

    I also wonder if Miles has such harsh words for other critics of the misrepresented top 25 managers’ earnings lists like Matt Levine at Bloomberg View. I’m guessing no as despite Matt and I repeatedly overlapping on this issue Johnson couldn’t misrepresent Matt’s career, history, and motivations in order to write the political screed Miles clearly wanted to pen.

    Miles, some advice. Click on a few hyper-links and actually read the background pieces. Try to understand the (admittedly narrow in my original piece) point of what you read, not the point you think the person might be making based on who they are.

    I 100% stand by the piece Miles criticizes and find his criticisms to be based entirely on a non-existent essay he thinks people like me would write.  Finally, I’m proud of my long history of balance and willingness to criticize and advocate for change in the hedge fund industry.


  4. A recent interview with Professor Eugene Fama represents another sign that much confusion about momentum unfortunately remains. While my faith in Professor Fama is exceptionally high, this is one of the few topics where we fundamentally disagree. While debates and discussions about momentum will undoubtedly continue, in this post I’ve tried to sort out fact from fiction by bringing clarity regarding the facts and interpretations about momentum and debunk some myths along the way.

  5. First, I must issue a disclaimer. This is for wonks already immersed in the factor literature. There's lots of inside baseball, assumed terminology, etc., in this one. I explain what I’m doing along the way, but rarely from scratch. If this stuff is brand new to you and you still understand it all you are way smarter than me (you are allowed to find that to be faint praise). There’s nothing more mathematical here than a regression model but there is lots of shop talk. So, if "factor wonk" doesn't describe you, you probably have friends and a social life, so that’s nice, but this piece won't make much sense (consider it even).

  6. CalPERS made big news today announcing it will end its investments in hedge funds. AQR has long researched and commented on the hedge fund industry and here we reference that body of work to put CalPERS's decision into context.

  7. Clearing up a misguided quibble over a previous post about the efficacy of the small-cap factor.
