Strategies vs. Systems (Part III)

In Part II of this series (http://www.optionfanatic.com/2012/05/16/strategies-vs-systems-part-ii/), I continued to argue that trading strategies are optionScam.com.  Let’s continue this analysis from another angle.

In the quest for consistent trading profits, traders are commonly discretionary or algorithmic in their approach.

Much ado has been made about the differences between these two.  If you are a discretionary trader then you have trading strategies with guidelines.  If you are an algorithmic trader then you have trading systems with rules.  The former relies somewhat on common sense and gut instinct.  The latter depends on programmable criteria that can be evaluated and executed by a computer.

At this point in my trading career, I strongly suspect that through a complex interplay of logic and human psychology including but not limited to the effect of wins and losses on emotions and memory, Maslow’s hierarchy, and ego fulfillment, discretionary trading may be optionScam.com at its finest.

That’s nothing short of a mouthful.  In future posts, I will break down each and every one of these elements.

The More Things Change…

…the more they stay the same?  This excerpt is from Gary Smith’s book Live the Dream by Profitably Trading Stock Futures, which was published 17 years ago:

“There are a handful of vendors that sell hyped and overpriced systems, seminars and trading manuals that purport to teach the public how to day trade the S&P successfully.  They recommend trading not only on a daily basis, but even several times during the day.  Off the floor it is an almost impossible task to trade profitably this way… I find it interesting that absolutely NONE of these vendors can prove that they are winning traders via multiple-year, real-time brokerage statements.  Their trading courses are total illusions.  They dazzle you with an array of historical charts and other past data to illustrate the purported validity of their methodology.”

On Quantitative Trading

“After the recent major losses at quantitative hedge funds, many people have started to wonder if quantitative trading is viable in the long term.  Though the talk of the demise of quantitative strategies appears to be premature at this point, it is still an important question from the perspective of an independent trader.  Once you have automated everything and your equity is growing exponentially, can you just sit back, relax, and enjoy your wealth?  Unfortunately, experience tells us that strategies do lose their potency over time as more traders catch on to them.  It takes ongoing research to supply you with new strategies.

There are always upheavals and major regime changes that may occur once every decade but will nevertheless cause sudden deaths to certain strategies.  As with any commercial endeavor, a period of rapid growth will inevitably be followed by the steady if unspectacular returns of a mature business.  As long as financial markets demand instant liquidity, however, there will always be a profitable niche for quantitative trading.”

Strategies vs. Systems (Part II)

In Part I (http://www.optionfanatic.com/2012/05/07/strategies-vs-systems-part-i/) I argued that trading strategies are optionScam.com.  A second reason for this claim is because trading strategies often assume you can predict the future.

Many option education programs teach you how to place trades to optimize the current trend of the market.  I have subscribed to two of these programs in my trading career at a cost of over $6,000 each.  One program teaches “form a market opinion and place a trade to optimize that market trend.”   The second program teaches “don’t try to predict market direction” and advises placement of non-directional “income trades” that make money if the market trades up a little, down a little, or sideways.

Although both programs spend hours teaching you how to place the “correct” trades, what actually determines profitability is whether your market expectation is correct.  Neither program spends more than a couple hours on this!  With regard to placing the trades correctly, I can save you $6,000 by listing a number of books under $30 or free web sites providing this content.  The only way to know if your process will sufficiently determine future market direction (sideways included) is to perform a valid backtest.

System development is the real work to be done and these “educational programs” teach nothing about it.

Because your market expectation may be wrong, both programs teach you to trade small to limit risk.  Trading small also limits gains, though.  The key question is whether these approaches even have positive expectancy.  This is a complicated question still up for debate and if the answer is no then at $6,000-a-pop you will be learning nothing more than how to lose all your money slower rather than faster.

Strategies vs Systems (Part I)

Trading systems are capable of generating consistent profits while trading strategies are optionScam.com (see http://www.optionfanatic.com/2012/04/21/optionscam-com/).

Trading strategies are available everywhere you look.  You can find trading strategies in books, through webinars, on internet sites–this list goes on and on.  Strategies are often marketed through long advertisements that promise huge ROIs and large compounded returns.

Trading strategies appeal to human greed.  They are sought after and commonly sold for hundreds to thousands of dollars.  Expensive trader education programs generally teach strategies.  If the market is bullish (bearish) then do X (Y) trade.  If the market is stagnant then do Z trade.  You can spend lots of money learning what kinds of trades will optimize what trends.  At the very least, this makes you dangerous although it may not make you profitable.

Trading strategies are well illustrated by single trades in isolation, which is hardly the reality of live trading.  By applying the strategy guidelines to a particular trade, you can learn its strengths and weaknesses.  Annualize that ROI (as if!) and human nature has already taken over.  “Imagine what X%/year can become over the course of decades!”  Human nature needs a reality check.  The only way to generate consistent income and meaningful growth is to trade as a business, which single trades in isolation are not.

A trading strategy is not a trading system because it lacks detail about money management.  Money management addresses Risk of Ruin for the entire portfolio.  Making money without studying this is luck at its finest–luck that will eventually run out.

For these reasons, trading strategies are generally not actionable.  This makes trading strategies optionScam.com.  In future posts I will go into more detail about this important concept.

Sizing Risk (Part III)

Sizing Risk is a common trading plan element that can pose a challenge to consistent profitability.

As discussed in Part I (http://www.optionfanatic.com/2012/04/26/sizing-risk-part-i/), these are scaling trading plans with a profit target of 15% and max loss of 20%.  Suppose $10,000 is allocated per tranche for up to three tranches.  The trade will then profit $1,500, $3,000, or $4,500–fifteen percent–depending on how many tranches are placed. When the trade loses, it will usually be after completely scaling in: 20% of $30,000 is $6,000 lost.

This monthly trade will therefore have to profit at least 75% of the time to be profitable.  If the trade wins eight months out of 12 and averages two tranches for each winning month then in one year it will make 8 months * $3,000/month = $24,000 and lose 4 months * $6,000/month = $24,000.  If the trade only wins seven months and loses five months then the annual return will be -30%.  Should it have a tough year and lose exactly as often as it wins, the annual return will be -60%, which is nothing less than a good recipe for grounding an account into hamburger meat.

As discussed in my posts on the naked put selling strategy (http://www.optionfanatic.com/2012/03/25/the-naked-put-part-iii/), a common worry amongst traders is to have one catastrophic loss that wipes out many profitable months. Sizing Risk teaches us that making too little in the winning months can be just as harmful to overall returns as catastrophic losses but is much more frequently overlooked.
