How can I trade in order to generate consistent profitability over time?  That is the $6M question most any trading mentorship program, educational program, or investing service is trying to answer.  None of them have the answer but all of them purport to have an answer.  Since my focus is mainly on options, I’m going to call this misnomer “optionScam.com.”

A scam is a fraudulent or deceptive act or operation.  A scam is when you pay for something promised that you don’t end up getting.

Most all retail traders dream of making consistent profits over time.  Out of fear and greed, the two emotions most commonly attributed to traders, we tend to be pulled toward outlets that promise this consistent profitability.

No program or service can truly provide us with such consistent profitability, however.  Regardless of whether we pay a couple hundred dollars or several thousand dollars, nobody can deliver on this promise.  Paying money to not receive the service promised is optionScam.com.

Proof of optionScam.com is like proof of arbitrage bounds.  A higher strike put must always cost more than a lower strike put.  A longer dated put (call) must always cost more than a shorter dated put (call) at the same strike.  A call must always cost less than or equal to the underlying price.  If any of these are violated then you could place a trade for guaranteed profit.  Similarly, if someone absolutely knew how to generate consistent profit over time then they could do the trade for guaranteed profit.  What would happen with arbitrage bound violations or the profitability promise is that others would execute the trade until the profit was no longer [guaranteed].

This is what makes any such promises optionScam.com.

Let me be absolutely clear:  IN ORDER TO BE A SUCCESSFUL TRADER YOU MUST AVOID optionScam.com.

To Optimize or Not to Optimize?

In the quest for consistent trading profits, backtesting is generally regarded as useful but optimization is viewed by some as a four-letter word.

If a system captures profits from consistent human behavioral characteristics reflected in the market then the past should reasonably approximate the future.  This will never be perfect but it may be profitable.

Optimization is the determination of what trading parameters applied to past market action would have resulted in maximal returns.  After all, if it worked well in the past then shouldn’t be likely to work in the future if the past is at least some small reflection of the future due to those consistent behavioral characteristics?  This is called curve-fitting.

One of the biggest scams on Wall Street is to present a system with brilliant historical returns (anyone can run an optimization procedure on backtested data to do this) and sell it as a system to be used in live trading.  Trading an optimized system into the future is almost guaranteed to underperform the past.  Selling an optimized system can be like selling snake oil, and charlatans abound in financial circles who aim to do just that.

To avoid excessive curve-fitting, some think that if you don’t optimize then you can’t fall prey to the illusion.  Choose only one parameter value and backtest it; if you come up with impressive results then they’re likely to persist into the future, right?

Not necessarily!

Suppose a system has one parameter (e.g. period for a moving average).  Imagine backtesting the system repeatedly over the historical time period while changing the period each time.  When you plot performance, does it look like this…

…or like this?

In both cases, using a period of A would have resulted in the best historical performance. However, in the latter case, if the period varied just a tad higher or lower then system performance was devastated. In the former case, trading with a period higher or lower than A would still have generated solid performance. Since the past is never identical to the future, which do you think has a better chance of generating profits going forward?

The bottom line is that “curve-fitting” and “optimization” are not four-letter words if used to know what you do not know.  Optimize not with the intent of finding the perfect parameter to trade going forward. Optimize with the intent to determine whether encouraging past results are likely to persist into the future.

 

Prevent Huge Portfolio Losses

One key to success in trading and investing is to prevent huge portfolio losses.  If you lose 50% of your portfolio, for example, then you have to gain 100% just to get back to even.  Off the top of my head, I can think of three ways to limit huge portfolio losses:

1. Diversify

What this really means is to include uncorrelated assets in your portfolio.  “Uncorrelated” means prices tend not to move in sync.  For example, if one goes up, the other goes sideways or down.  Alternatively, if one goes way down then the other goes up, sideways, or down a little.

The danger of diversification is that in extreme circumstances correlation can go to 1, which means everything moves together.  You could be invested in markets that had historically been uncorrelated but when the crash hits, everything goes down.  We saw this in fall 2008 when gold, bonds, and the stock markets all fell precipitously for a while.

2. Position size to limit total exposure.

If you are only 10% invested then the most you could ever lose if that asset (e.g. stock) goes to zero is 10%.  The remaining 90% of your portfolio would be in cash.

3. Buy puts

Put options profit when their underlying markets fall.  Options were originally created to serve as insurance and this is exactly what long puts can do.

Other ways of achieving this goal are to short markets or to buy inverse ETFs.

Stow Your Ego Before Trading

Here’s a worthwhile quote from acclaimed systems developer Thomas Stridsman: 

“It is only a question of how long you stick around. If we all stick around long enough the probabilities have it that we all will be wiped out sooner or later. It is just a matter of time.”

Once upon a time, I lost 50% of my total net worth in a span of less than two weeks.

Been there done that and hope to never live through such an experience again.
