I'll
have a go at defining pairs trading for you.
<FONT face=Arial color=#0000ff

To me,
there are two different kinds of pairs trading (fundamental and
technical).
<FONT face=Arial color=#0000ff
size=2>
Before
I get into that, however, I'll start by telling you that pairs trading is
NOTHING MORE than buying one stock and shorting another. Usually, the
dollars invested would be the same for each stock.
<FONT face=Arial color=#0000ff
size=2>
<FONT face=Arial color=#0000ff
size=2>Fundamental pairs trading would be based on YOUR INTERPRETATION of the
fundamentals for those two companies. If you spent the time to
review the annual reports for Ford and General Motors, for instance, you might
decide that FUNDAMENTALLY Ford should outperform General Motors over the next
six months. So, you would buy Ford and short General Motors.
Your trade, in theory, should not be affected by any move in the entire market
or even the automotive sector. At the end of the six-month period
you would liquidate both positions.
<FONT face=Arial color=#0000ff
size=2>
<FONT face=Arial color=#0000ff
size=2>Technical pairs trading is a little more complex. Again, you
would be buying one stock and shorting another. Most pairs
traders might only trade a "pair" that were in the same sector, but that isn't
necessarily a requirement. The idea here is that you find two stocks
whose average daily returns move very much in unison. I won't
get into the math for determining this, but I'm sure you get the
picture. Let's say that you discover that the daily
returns for Ford and General Motors almost aways move together.
You also observe that if the returns move apart.... they tend to come back
together. You also observe the maximum amount that they varied
over some period of time. When you see them move apart by that
amount again, you simply short the one with the higher returns and buy the one
with the lower returns. Finally, you just wait for the returns to come
back together and liquidate both positions. Again, the
theory is that any major move in the overall market has no effect on your net
position.

I
might add that many, if not most, of the professional fund managers using pairs
trading haven't done very well over the last quarter, generating negative
returns for their investors. I've been pairs trading for two
years, netting just over one percent per month for investors in that particular
fund. I can also tell you that, in my opinion, any attempt at
fundamental pairs trading is doomed for failure.

Re: Dynamic Indicators Poll -- VOTE AGAIN,
PLEASEYes. I know. See my previous post, but for
example I don't want to have to write my own Stdev routine for variable
periods where it would require a For loop or a script to get it
done. As I've said before, IMHO the best thing about AB today is
it's speed and the LAST thing I want to do is slow it down w/For loops
if I don't have to. The best thing about the future of AB is of course
the support & potential enhancements and I'll be happy to take the
latter in whatever order Tomasz thinks best with my own personal
preference at the moment being the fixing of position size transactions
being automatically limited to total available cash followed by some
other aspects of portfolio trading i.e. pairs and ranking
etc.--- In amibroker@xxxxxxxxxxxxxxx, "DIMITRIS TSOKAKIS"
