AQR Hedge Fund moving into Trend Following

Quote from JezLiberty:

re: Superfund, yes, this is the issue when CTAs offer multiple funds. I just have to pick one,

Looks like the various Superfund products were down anywhere from 16.5% to 32.5% for the month of May. Ouch. Significantly worse that most other trendfollowers.
 
Thanks - I'll try to add those - but as you say, its not always easy to find CTA performance reported every month (ie some CTAs only make it availabelt ot clients, etc.)
 
Quote from zodiacmindwarp:

nieder always makes thing more complicated. its simple--above 20o day SMA buy pullbacks, below, sell upthrusts.

nothing to it.

Interesting... any way to computerize this algorithm?

And maybe 200 day SMA is popular only for stocks not commodity futures?

Thanks!
 
Quote from Daal:

The fact that the funds are still here and VN isn't is not significant evidence that TL works or that mean reversion doesnt work. This is the same small sampling type argument michael covel makes in his flawled book 'Trendfollowing'

What's the flaw in that book?
 
Quote from JezLiberty:

Thanks makloda, exactly my point :D

The probem is that people have a short/selective memory...

And many still hold the old Vic as a master trader...

There are many other examples, look at LTCM.. And John Meriwhether is opening his new fund after blowing up the one he set up after LTCM! :confused:


@Daal
I dont really want to get into an endless debate on this TF v MR, but I believe the examples are here to illustrate the theories/concepts behind it (and not the other way around):
- risk of ruin is increased by leverage/optimization of results (which is what mean reversion typically is about)
- markets exhibit fat-tail events and if you trade against them, you increase your risk of ruin, hence it makes sense to use a strategy that benefits from them (read Trend Following)
- you cannot predict...

A book that is much better than Trend Following to illustrate some of these points, imho, is The (mis)behavior of the markets by Mandelbrot. It is also very entertaining to read (I think it is better than Taleb's Black Swan and definitely much less arrogant - if any!)


All that being said, I believe from a pure business point of view, it might make more sense to set up a fund similar to Niederhoffer, LTCM, etc:
- your strategy makes people think you are very clever and can identify inefficienc
- people forget quickly about blow-ups
- your performance until you blow up will be much more impressive than TF funds, bringing lots of forgetful clients, bringing more AUM, and bringing in even more fees (both based on performance incentives and more AUM).

Now, if we talk about business ethics, long-term client relationship, it might make more sense to use a strategy that will ensure decent return and survival over the long term (read Trend Following)...
:cool:

What's the definition of blow-up here?
TF can also have very large drawdowns and it's embeded in its roots.
What strategy does Niederhoffer use?
I don't think people use only one strategy... they all run as many strategies as possible.
 
Blow-up: see Amaranth, LTCM, Niederhoffer, etc. basically holding positions that go the wrong way and keeping holding until the losses are too big that they "blow up" and force you to unwind the position and close the fund.

Typically happens with Option-writing strategies: look (very) good until they blow up by a Black Swan event.

This never happens with Trend Following thanks to the use of stop losses - of course there can also be large drawdowns resulting from many small losses, but the art of Money Management is to make sure that these strings of small losses keep you in the game until the next big moves..

Not sure that Dunn, JWH, Chesapeake, Abraham, Eckhardt, etc. use anything else than Trend Following at the root of their strategy...
 
Quote from makloda:

IMO, this "trend" or "direction" non-sense isn't half as important as the idea of volatility-based position sizing, letting winners run and cutting losing positions relentlessly (without averaging down). I believe it was David Harding from Winton Capital who said something along the lines of:

"You could even enter in a random direction, we tested it. If you just let your few winners run and cut your losing positions fast then you would have made money historically". I believe it was in one of his interviews somewhere.

Is it possible?

You mean use random signal + trailing stop?

Please quantify as precise as possible. Thanks
 
Quote from psytrade:

Trend followers get the biggest edge when other people are short volatility - because at that point, risk is cheap, and TF's can pick up contracts with low risk entries or exits... and with less volatility/slippage on their positions.

That is why, implicitly, "the flaw" that TF funds trade off of cannot go away, as long as people sell volatility.

The only time the effect of being short volatility works against them is during a Market intervention where government positions the Market to work in favour of those short volatility. Unfortunately for trend followers, for a number of years, 2009 included, Market intervention has created something like a "synthetic trend" that a trend follower cannot easily enter into.

Interesting. So you mean TF works best when the vol of a security is low?

TFs made lots money in 2009.
