Quote from JezLiberty:
I ranked Trend Following CTAs and funds including Superfund, it was ranked as the second worst of all the managers, providing negative value compared to a simple and cheaper benchmark...

Thanks makloda, exactly my point![]()
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!![]()
@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)...

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.
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.
