Investment Strategies - Why Logic Is Important

By Gnifrus Urquart

One of the things I have noticed during the 20 years I have spent either actively investing in various strategies, or trialing them, is that the ones which make logical sense usually are the ones which work best in real life.

Lets face it, you could spend 2 life times trialing all the investment strategies people offer you. There are so many out there and I am sure most of them have some merit. What I have found though (and this in no way passes judgment on the merits of any investment strategy) is that if I really think logically about many of the investment strategies which have come my way, there are often holes in them... big ones at that too.

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.

Also, the point about trialing a strategy is that you are finding out whether it will make consistent returns over the fullness of time. The point about trading a strategy is that you know it makes consistent returns over the fullness of time. If you have had a guess mid way through the strategy, you cannot be confident its the strategy or your guess which is making the money. You will need to start again.

So if someone presents you a trading strategy, go through the logic with a fine tooth comb. See if you can come up with scenarios which may happen in real life, which the strategy deos not cover. If you can think of some, try to get answers for these scenarios before you start trading with real money. Because believe me, if such scenarios exist, as soon as you put money down they will come up. I think 2007 - 2009 taught us all that.

And don't forget to dummy trade before you put any money down. When you are dummy trading you will most likely find a bunch of trading scenarios you never thought about before. Make sure these are covered by the logic of the strategy too. Its much easier to sort this stuff out without money, than when you have money on the line. - 29971
