Trust your Edge

By April 17, 2009May 8th, 2024EDGE Thinking, Uncategorized

Traders employing a discretionary or subjective bias to their decision making can suffer enormous swings in their emotions – from euphoria when they get a winning trade, to dread and horror when they lose. Anyone hoping to achieve longevity and long term success in the markets can not trade in this way. It is simply not sustainable over the long term, because there is no plan in which to trust.

The dictionary defines trust as “reliance on the integrity, strength, ability, surety, etc., of a person or thing; confidence”. Many actions we trust inherently because the results are well within the emotional bounds between life and death. Take every day driving of a motor car. Every time that we drive a car there is a chance that we could get killed in an accident. There is nearly one motor car fatality every day, on average, in each state in Australia. However we don’t get behind the steering wheel and fear our impending journey. Why not? Two reasons. Firstly, we trust our driving skill and, secondly, we inherently know and trust that the probability of a fatality is extremely low. That is, we trust in the probabilities of getting to our destination alive. The roads are a probabilistic environment.

Other actions, including execution in the market, require that trust is earned, both in our own skill and in the probabilities that exist in executing in the market. The market is a probabilistic environment.

Much of the trust for executing in the market will come from having a well developed and researched process that you know produces a positive outcome over the long term across a wide range of market conditions. The research and development is your preparation as discussed in last week’s blog. The output is a trading system that is part of a trading plan that defines the process. The trading system must have an edge. The edge is defined in terms of probabilities and it is these very probabilities in which you trust. There is no certainty in any trade yet there is certainty over a large sample of trades because the probabilities of the edge will be met.

To find a trading system that has an edge you must make a decision; you either spend considerable time gaining the knowledge and conducting the research to build an edge, or seek out an existing and proven edge to buy. Build or buy?

Most people who choose to build never complete their edge, or at least to the point that they trust it, and hence never get to the point of executing with a predefined edge in the market. Building is only suitable for a very small percentage of investors who have the necessary skills, time and mindset. It is tough work building an edge but for those who do, it is very rewarding.

Buying an edge involves a leap of faith. To take that leap of faith there is some fundamental information that should be sort. You need to assess the builder’s qualifications, experience and ethics, and ensure their researched edge is transparent and works. The ultimate proof is the equity curve over the long term through multiple market ups and downs. It is not the result of each trade that matters, or even a few months trading – it is the overall result of the edge over multiple market conditions over a large sample of trades, including brokerage and slippage. This level of proof goes well beyond the much maligned black box systems that are regularly sold to the unwary. Trust is “reliance on the integrity and qualities / attributes” of the edge.

By choosing to buy an edge, your time can now be spent developing other areas that build trust and allow you to execute with confidence. This includes developing your trading plan, learning the processes of your trading system, improving execution and developing your trading mindset. By sticking to the rules of the trading plan, you are able to execute the trades as and when they come along with no emotional attachment to the outcome of each trade. That’s trust!

Trading is an endurance activity not a sprint. In order to survive over the long term we must have a process and set of rules we can trust. It is the probabilities of the system over the long term that we need to understand and trust.

My friend the bike rider who featured in last week’s blog, trusts his bike 100%. He prepared first and trust followed. He chose to employ, buy, a mechanic with the desired qualifications and proven experience to build a bike he can trust. As a result, my friend is able to focus on the planning and execution, pushing himself to the limits of endurance because he has the confidence to do so. This trust gives him an edge over other riders who may not have developed the same level of trust with their bike, and even with their own mind and body. Those that lack this level of trust and thus confidence, are not able to perform as well under pressure or after more than 20 hours of gruelling physical and mental endurance.

Preparation….. trust…….confidence…….execution.

Trading the markets is the same. We need to have trust – in the edge of our system, the development and workings of the system, and most importantly, ourselves. There is no other high probability way of doing it. Preparation will develop trust which will develop confidence which will overcome the emotional turmoil of fear, uncertainty, doubt and trepidation that the markets would otherwise deliver.

I have learnt that you cannot trust and fear (or worry) at the same time. So which of the two will it be for you when it comes to the market?

    Hi Gary, your journal of 17/4 really struck a chord with me. I have spent the last 5 years honing my own phsychology so that I can consistently make money in the markets on balance, and you have nailed what it is all about exactly. Thanks.

    Hi Gary,
    re: “You need to assess the builder’s qualifications, experience and ethics, and ensure their researched edge is transparent and works.”

    Where can I find transparent information on the researched edge that is used by SPA so that an independent assessment and analysis can be done or is this proprietary information that you don’t want to disclose?

    Hi Victor,

    In answer to your two questions; is your ‘ShareFinder ‘system suitable for SMSFs? I would say between 60% and 70% of the ShareFinder customer base use SPA3 through their SMSF. This is due to the nature of the product requiring a minimum capital injection of around $80K.

    Could I manage amounts in excess of $1,000,000 ? In regard to managing a rather large amount of capital we would suggest that customers would consider splitting a $1 million over two portfolio’s (2 x $500K). This is purely due to the illiquid nature of the Australian market (especially in a bear market) when looking at stocks outside the top 300 in market cap. Our training documentation clearly discusses this issue and suggests that a portfolio of $500K would have 22 open positions. This is another journal posting in itself!

    “Where can I find transparent information on the researched edge that is used by SPA so that an independent assessment and analysis can be done or is this proprietary information that you don’t want to disclose?”

    For prospective clients:

    1. All trades that have been completed in the publicly traded hEdge portfolio can be downloaded for your own analysis from the following link: Click here.

    ALL trades over 8+ years, long and hedge trades, are shown, including brokerage.
    The first 2 years of this portfolio were audited by Personal Investor magazine and the 2006/2007 FY was audited by Deloitte. The portfolio file can be downloaded at any time (every day if they wish) by customers who have the SPA3 portfolio manager software to analyse etc.

    A portfolio equity curve over a large sample of trades over a number of market ups and downs compared to the market index is the ultimate proof of whether an edge works or not. The equity curve is provided at the same link above.

    2. The Forum that our customers use can be accessed by prospective clients to view all the discussion that takes place by clients. Guest access to ask any question you like is possible if you contact us.

    3. Qualifications, experience and ethics: well I guess this needs to be assessed from the success of SPA3, the information provided by us on the website, direct contact with our team, examples of articles that I have written in magazines and elsewhere since 1999, the DVD that we send to prospective clients, assessing my style on SkyNews, this Blog, and any presentation that you may see me do for ShareFinder or any association that I am invited to present at. Ultimatley this is a trust issue.

    For clients:

    1. The SPA3 tools allow our clients to conduct the same SPA3 research and backtesting that we can do internally. The only difference is that internally we have a research database that includes delisted stocks since 2000 whereas clients are shipped a fully maintained historical database.

    2. Our Members Zone has a number of Advanced Coaching Notes that details the research conducted on SPA3. These are to be used in conjunction with the SPA3 documentation.

    3. The SPA3 documentation details all the rules and much research.

    I trust that this helps.
