Financial Markets as Complex Adaptive Systems

More is Better Part 3
Harping back to our little friends once again; when is a group of ants a colony?
Apparently, critical mass is achieved at about 30 to 40 ants with an efficient
colony having a population of at least 100 or more. The key point here is that there
is a minimum requirement and the general rule of thumb is…the more, the merrier.

And so it is with financial markets and individual shares. Recognizing of course
that the investors in any individual share are the independent yet freely interacting
agents whereas in the case of an Index, the shares themselves are the independent
yet freely interacting agents.
Thus an example of an inefficient CAS would be the Dow Jones Industrial
Average which is made up of only 30 constituent stocks which represents about
20% of the NYSE by market capitalization. (note that I am not saying that the
NYSE is an inefficient CAS but that the Dow Jones is a poor representative of it)
The above chart of the Dow Jones has two key features. Firstly, where the index
rises above 10,000 points, note the degree of indecision as indicated by the
sustained sideways movement and the magnitude of the candlestick shadows, ie.
the candlesticks have this sort of fuzzy, out of focus appearance. Secondly, during
2002/2003, the Dow dropped away but didn’t manage to reach its historical norm.
Now take a look at the following chart of the SP-500 Index, which is made up of
500 constituent stocks, and you’ll see that it tells a different story…
Firstly, the pullback in 2002/2003 does manage to touch down on the historical
norm and whilst the SP-500 includes constituent stocks from the NASDAQ as well
as the NYSE, it is primarily created from NYSE stocks.

__________________________________________________________________
Secondly, but no less important, where the SP-500 forms a peak at about 1,500 at
the turn of the millennium, there is virtually no sideways consolidation and far less
candlestick shadow occurring, indicating much more decisive market behavior.

So whilst the Dow Jones clearly displays chaotic and fractal behavior (see the Dow
from 1994 to 2003), it makes for a poor CAS as it displays indecision at the market
extremes and seems reluctant to form linear boundaries, even over the long term.
__________________________________________________________________
__________________________________________________________________
Hence the more agents within a CAS the better…30 is poor, 100 is OK and 200 or
more is good to excellent. Thus understanding and interpreting financial markets
as complex adaptive systems is definitely a technique suitable for dealing with
large capitalization, liquid instruments and not for trading penny dreadful shares.
Appropriate Trading Tactics
As you’ve probably already surmised, linear trading tactics are best used to trade
the boundary effect and non-linear techniques for trading non-adaptive chaotic
behavior (which principally occurs when there are an insufficient number of agents
to support self organization and/or the market is in a transitional phase)
Non-linear trading tactics include…
•
Elliott Wave Theory
• Gann
•
•
•
Fibonacci retracements and price projections
Volatility based techniques including price projections & turning points
Volume based techniques including continuation and turning points

Linear trading tactics include…
• Trendlines
•
•
MACD, moving average convergence divergence indicator
Rate of Return measurement
• Fundamental analysis
• Momentum oscillators including indicator/price divergence
• Range or channel trading tactics
__________________________________________________________________
__________________________________________________________________
__________________________________________________________________
And of course, there are some universal indicators and trading tactics as well;
•
Moving averages and applications, ie. crossovers
• Multiple moving averages
• Support/resistance levels
• Range Indicator
• Count Back line
• Swing trading

__________________________________________________________________
Thus everything works and everything doesn’t work. Therefore viewing financial
markets as complex adaptive systems doesn’t in any way invalidate any pre-
existing concepts in technical analysis.
__________________________________________________________________
__________________________________________________________________
__________________________________________________________________
What this new found understanding does do however, is tell us which technique is
the most appropriate for any given circumstance. Thus the MACD which is usually
notorious for giving false entry/exit signals (whipsaws) is far more effective if
used in conjunction with the identification of linear boundaries….
