Stewart Develops a Genetic Algorithm for Designing
Fidelity Sector Fund Strategies
Stewart Wilson's effort to develop a genetic
algorithm for selecting a set of 12 Fidelity sector
funds as members of a SectorSurfer Strategy was
first reported in our
January 2017 Newsletter. About a year earlier,
Stewart contacted us about experimentally developing
a genetic algorithm to pick funds from a set much
larger than the 12 funds a SectorSurfer Strategy can
hold, such as the 40 Fidelity Select sector funds.
The purpose of the genetic algorithm would be to
automate the fund selection process and completely
remove any human-induced hindsight selection bias.
Even though
Forward-Walk Progressive Tuning is employed, a SectorSurfer
critic would be on reasonable grounds to ask
"When did you pick those funds?" Answering
"today," results in the critic saying "Obviously you picked
those funds in hindsight knowing they would do
well." While it is possible to carefully select a
set of strategy funds that have no hindsight bias (by
including representatives of all market sectors), a
genetic algorithm simplifies the problem by
inherently eliminating hindsight selection bias and the associated risk of future
underperformance associated with it.
Unfortunately,
Stewart and I quickly found we had significant
compatibility problems between SectorSurfer's
Windows-based server and programming languages
versus Stewart's Linux operating system and Lisp
programming language (more common among academic
researchers). Even simple file sharing was a problem.
However, we were mutually determined to proceed and
agreed that Stewart would first have to recreate
SectorSurfer's fundamental momentum and differential
processing
algorithms by using little more than emailed
descriptions. Only then could he begin to layer his
genetic algorithm for evolutionary fund selection on
top. Over the course of about a year, Stewart's work
eventually began to bear fruit as illustrated by individual
Strategies of this portfolio, each of which was designed by
his genetic algorithm and imported into
SectorSurfer to confirm the performance indicated by
his software.
This Strategy-of-Strategies includes
nine candidate
Strategies that were created (funds selected) by
Stewart's genetic algorithm in late 2016. Although
initially created without the benefit of
Forward-Walk Progressive Tuning, each of these
underlying Strategies have had this feature enabled
with the corresponding
BornOn Date of 1-4-2010 and thus will be able to
automatically adapt to future changes in market
dynamics. Note: At the SOS top level, StormGuard
is disabled because it was deemed to be the
responsibility of each underlying Strategy.
Stewart's work was both proof-of-concept and
inspiration for the 2018 development of our Merlyn.AI genetic
algorithm, which takes this work to the next level,
where (1) strategies incrementally evolve monthly;
(2) StormGuard Armor, Bear Market Strategies and
Forward Walk Progressive Tuning are fully
integrated; (3) portfolios of Strategies can be
created and managed; (4) larger sets of ETFs and
mutual funds are easily managed for sector and asset
class strategies; (5) exclusion of unsuitable funds
is automatic, and (6) the proper files and
connections are made so that it can integrate
seamlessly with our SectorSurfer and AlphaDroid
platforms.
We are very happy to now have Stewart onboard as our AI
Science Advisor to help us get our Merlyn.AI
technology right and ponder future improvements. We are also happy (in hindsight) for
the system compatibility problems we initially had
because the independent recreation of SectorSurfer
in Lisp by a professional and academic of Stewart's
stature provides serious validation of
SectorSurfer's underlying concepts and algorithms.
What is a Strategy-of-Strategies?
A SectorSurfer Strategy selects the trend leader
from among a set of candidates — and for a
Strategy-of-Strategies (SOS)
the candidates are a set of Strategies instead of a
set of stocks or funds. Since each of the SOS
underlying Strategies have already been maximized
for performance, there is generally only minimal
further upside performance that can be extracted.
The primary benefit of an SOS is to make sure that
you stick with the best performing of the candidate
Strategies and steer clear of the others.
For example, if the Strategy you own gets a "flat
tire" for some period in the future because you just
didn't quite have the perfect set of candidate
sector funds, it's quite likely that one of the other
candidate Strategies will still be performing well
and will be automatically selected for you by the
Strategy-of-Strategies. Thus, a
Strategy-of-Strategies is a form of insurance
designed to reduce future risk of Strategy
sub-performance.
Instructions for building your own
Strategy-of-Strategies can be found HERE.
What's This ?

Although implementing a typical
Strategy-of-Strategies would require using 4 to 5
normal Strategies and have a
corresponding subscription price of $40 to $50 per
month, a Master SOS can be
imported into your account for a fraction of that
cost. However, a Master SOS is priced higher than a
standard Premium Strategy. The X factor is specified
in the left column of the Select-a-Strategy popup
and of your Strategies list where "Paid 3x"
indicates that it will be charged at a rate 3x
that of a normal Premium Strategy.
|
SOS Construction
A
Strategy-of-Strategies is composed of multiple
candidate Strategies, of which only the trend leader
among them is selected to finally determine which
one fund will be owned next month. All of the
Strategies are generally related in some way and are
intended to have (or allow) a degree of redundancy
in their construction because the job of a
Strategy-of-Strategies is not to choose between a set
of ideally uncorrelated assets, but rather to choose
the Strategy best formulated for current
market conditions as evidenced by its current
performance.
The
Underlying Strategies
Each of the underlying Strategies is configured
with a set of up to 12 funds, each representing a
different slice of the market; sector, country,
commodity, or asset class. SectorSurfer's algorithms
determine which fund is designated best-of-breed
based on its trend leadership. The yellow line on
each chart plots the performance of the strategy,
which owns only the designated best-of-breed fund at
any given time. This is True Sector Rotation (or
serial diversification) and is a powerful investment
ally best appreciated through its performance.

Stewart Wilson's Genetic SOS (w/
Painted Path)
for the SOS
SectorSurfer Strategies typically produce only about four trades per year, and Forward-Walk-Progressive-Tuning,
the industry gold standard for backtesting, has been incorporated.
|
SOS Performance
The SOS chart (top-right) plots the performance of
each of the contributing strategies in grey, the
S&P500's performance in white, and the
Strategy-of-Strategies in the multi-colored Painted
Path format where each of the colors indicates which
of the Strategies was selected at that time.
As previously indicated, the Strategy-of-Strategies
purpose is not to extract additional great returns, but to
act as a form of insurance designed to reduce the
risk of sub-performance in the future should one of
the Strategies get a "flat tire" for a while.

Why
Taking Control Urgently Matters
|
Diversify and Rebalance? Why
Be Average?
The financial industry has hypnotized us
into believing diversification and
rebalancing is the only worthy investment
strategy. But diversification inherently
means owning a little bit of everything —
which is the formula for achieving precisely
average performance! Rebalancing further ensures
we
won't stray far from average. No other industry
proclaims average performance is the best
you can achieve. Fortunately, it's not true
here either.
Change the Game!
To achieve a different result
requires a different approach. Price momentum has long been proven
the best predictor of future returns. Simply
by owning momentum leaders and avoiding
momentum laggards one can simultaneously
improve returns and reduce risk of loss. No
diversification compromise! SectorSurfer
further maximizes performance utilizing
digital signal processing theory and
automated strategy tuning.
An Extra 10%
Really Matters
Before Retirement:
The
Nest
Egg Value chart
illustrates how an additional 10% annual
return compounds over 15 years to produce a
nest egg four times the value it would have
otherwise had. The earlier you start, the
greater the multiple. It really matters!
After
Retirement: The Nest Egg Annual Income
chart illustrates how portfolio return
affects the inflation-adjusted annual income
you can take, assuming a $100k
nest egg, 2.5% inflation, and 30 years of
retirement to fund. In the illustrated
example, investing in the S&P 500 would
likely allow an income of $14,000/yr.
However, earning an extra 10% increases it to
$36,000/year. Again, it really matters!

What is True Sector Rotation?
|
The Trend is Your Friend
Trends and fads are an inherent part of
human character. It takes time for
information to spread, to be understood, and
to be acted on. This creates momentum.
Price
momentum is found in all capital
markets, including stocks, bonds,
treasuries, and currencies. By its very definition,
"trend" means that information from the recent
past tells you something about the near future.
SectorSurfer's trend analysis algorithms use modern digital
signal processing theory to optimally
extract trend signals from noisy market
data.
|
True Sector Rotation
The
market cycle is tied to the economic cycle.
Each market sector performs best during a
portion of the economic cycle. If you think
of each market sector as a piston in your
investment engine, the smoothest, most
powerful ride will be achieved when each of
the major market sectors is represented in
your portfolio ... but only while each is
delivering its power stroke.
By owning only the top trend
leaders and avoiding trend laggards one can
simultaneously improve returns and reduce
risk of loss.
That's True Sector Rotation!
Diversify and Rebalance?
Diversification inherently yields
precisely average performance. Master investor Warren Buffet
instructs us:
"Wide diversification is only
required when investors do not understand
what they are doing.

How
StormGuard Reduces Risk
|
Risk is About Losing Money!
The definition of risk depends on who you ask. The financial industry
uses
the coefficient
of variation (CV) to measure risk, which tells you how
wiggly the line on the chart is, but not the
probability of losing real money. Treating
both up and down-moves equally as risk is an
unfortunate consequence. Only down-moves
contribute to real loss. SectorSurfer's risk
measure is the
probability of
a 15% loss
in a year.
StormGuard
Measures Market Health
Not only do SectorSurfer's trend-following
algorithms inherently steer around and avoid
poorly performing funds, but its StormGuard
Indicator monitors overall market health
and advises a move to the safety of a money
market fund when market storms approach. The StormGuard Indicator is
calculated daily from a basket of broad
market indicators.
Optimized for Minimum Probability of Loss
The StormGuard Indicator optimally tunes
itself for the minimum probability of loss
according to the character of the
constituent funds/stocks of each
SectorSurfer Strategy by balancing the
probability of whipsaw loss from reacting
too quickly
to market dips against the
probability of loss from reacting too slowly
to major downturns.
Diversify and Rebalance?
Warren Buffet instructs:
"Risk can be
greatly reduced by concentrating on only a
few holdings."
SectorSurfer practices
serial diversification
by owning many very different things,
just one at a time.

SectorSurfer's Algorithm
Validation
|
Overview
SectorSurfer's validation is confirmed
by the
validation of each principle detailed in the
paragraphs below.
Trend Signals Exist in Market Data
In his 1996 book
Chaos and Order in the Capital Markets,
Edgar Peters applied the Hurst Range/Scale
analysis method to data from all capital
markets, including stocks, bonds,
commodities, and treasuries. He found that they
all have a significant short-term trend component that
dissipates after numerous months.
• See Hurst Exponent Reveals Trends on
the Sector Rotation Theory Page for further
technical information.
Momentum Strategies Really Work
When you can get the media, industry, and
academia to agree that something is real and
works, then you know you really have
something. These three momentum trading
articles do just that:
• The Economist:
Momentum in Financial Markets. A survey
of strategy results and expert commentary.
• Columbine Capital
Price Momentum - a Twenty Year Research Effort. Industry momentum white paper.
• Jegadeesh & Titman
Profitability of Momentum Strategies.
A fundamental academic momentum paper.
SectorSurfer's Performance is
Trend Based
How can we tell that the trend signal we
extract from the noisy market data really
does drive SectorSurfer's performance? The
Hurst exponent measures the quality of the
trend signal and has a month-end bump in its
character. This bump is a fingerprint
likewise found in the character of
SectorSurfer Strategy performance.
• See SectorSurfer's
Trend Fingerprint on the Sector Rotation Theory Page for
further technical information.
Trend Signals Exhibit
Stationarity
Stationarity refers to the character of a
random process remaining the same, such as
the distribution in heights of men, shoe
sizes for women, or trend lengths in market
data. Stationarity enables one to
confidently manufacture shoes of various
sizes even though the shoe size of the next
customer is unknown. Backtesting provides
assessment of market character. Stationarity
in market character enables strategy design
to learn from the past in order to improve
one's batting average for future investment
choices.

Signal Stationarity on the Sector Rotation Theory Page for
further technical information.

Background
"Diversify and Rebalance" was born with MPT (Modern
Portfolio Theory) in 1950 when we had
rotary dial telephones. Today the telecom
industry has wireless digital cell phones
with touch screens, video cameras, voice
dialing, and GPS maps.
But,
the financial industry is still selling us 1950s
diversify and rebalance?
Extracting the Trend Signal is Everything
If the EMH (efficient
market hypothesis) were true, the future
would be random and the
Hurst exponent of market data would be
exactly 0.5, but it's not, because market data
contains significant trends. A trend
means that information from the recent past
tells you something about the near future.
There is nothing more important than to
apply the best signal processing
technology available to extract the trend
signal from noisy market data to improve one's
investment batting average. (Here's why, MPT is blind to trends.)
Differential Signal Processing
One of the most fundamental methods for improving the
signal-to-noise
ratio in data communications is
to eliminate common mode noise via
differential signal processing. That's why it's built into
Ethernet and USB.
Most charting and analysis software
evaluates ticker symbols independently,
which taints the analysis with common mode
market noise resulting in excess whipsaw
losses reacting to noise unrelated to its
own relative performance. SectorSurfer's
simultaneous
differential analysis eliminates common mode noise.
Matched Filter Theory
Matched filter theory provides the basis by which
trend signals can be optimally extracted
from noisy market data. The well-known academic paper
Profitability of Momentum Strategies, by Jegadeesh & Titman
used a simple equally weighted SMA (Simple
Moving Average) of length 6 months as its
trend measure. However, neither the SMA nor 6 months are near optimum
compared to the Matched Filter Theory solution. Simply put:
better trend analysis produce better results. See this
summary comparison and the Strategy Hall of Fame.
Automated Strategy Optimization
Investors familiar with technical chart
indicators know how tedious it is to
determine which indicators and what
parameters to use. SectorSurfer completely
automates this process for you. Better
results, less time!
