Logic In Investment Strategies

I’ve been trading stocks and forex all my life. One thing I gradually became aware of during this experience was that the strategies which make the most logical sense typically are the ones which work the best.

There are so many strategies I’ve tried, I have lost count. And there are at least as many which I’ve let go without trying. There are just too many. I found a quick fire way though which helps disregard the strategies which are useless, so you can trial the ones which are worth trialing. Its logic. Look at the logic of your trading strategy and see if there are holes in it. You’ll be amazed by the number of strategies with big logical holes.

Strategies generally make sense. The problem I am talking about is not about making sense, it concerns completeness. When these strategies do not cover all possible scenarios, you can be left in a position where you need to make decisions that are not following the strategy. The amount of judgment you can bring to such forced decisions depends on how close this situation is to others covered by the strategy. In a worse case scenario, it could be a complete guess.

When I am in this situation, where I have to make a decision outside a strategy I am trading because the strategy does not offer me guidance, I believe I am gambling. This is not good. I may make the right decision, but then again, I may lose my money. In all good investment strategies, you should not have to do this. You should simply plan the trade, and then trade the plan. There should not be room for guess work.

The other problem with this is that no matter what happens to your returns from that point, you will never know if it happened because the strategy worked or because of the guess you just made. This also can create problems as it must impact your confidence in the strategy. If your confidence is impacted, this may further cause you to divert from the strategy in other circumstances, exacerbating the problem.

So if you have a new strategy which looks promising, apply your logic to it first. Try to understand all the trading scenarios you may face and ensure the strategy stands up to all of them and deals with them. This simple piece of advice could save you thousands.

And once you have covered off every situation you can think of, always remember to execute a preliminary trading exercise without putting money down. Spend a few months running the strategy in spreadsheets before you trade with money. You’ll be amazed at the real life situations which come your way which you’d never have dreamed of. And you will thank your stars you resolved these issues when you had nothing on the line.
