You know what?
I suspect the reason why many investors and traders get so interested or hung-up on their annualised performance in percentages is because they are right-handed.
Right-handed means left-brained, and that’s the domain of numbers and analytical skills.
I always have a laugh when I see people write their performance down as in + 10.23%
A 10% rounded is not good enough… Must also include .23… Well, I guess 10.23% beats someone who got 10.21%
So competitive!
Let’s take a hypothetical example of Mr X’s annual investment/trading returns:
Year 1 = + 100%
Year 2 = - 50%
Year 3 = + 30%
Year 4 = - 23%
Those good in math will know immediately that this person – after spending 4 ears in the market – has “lost” to someone who has put the same money in a savings bank.
So by looking at the numbers, how can Mr X improve his performance for next year?
Eh… (Of course can but with lots of assumptions! And the usual platitudes like let your winners run and cut short your losers, etc…Don’t you want to puke if you hear another hackneyed book “advice”?)
Unless you have the memory of an elephant, may I suggest an Investment Diary or Trading Journal to complement your addiction to numbers?
You can just Google or search in Youtube for the many suggestions on how to go about it.
Choose a medium and format that suits you.
I personally use a spreadsheet. This way, I have the database of individual trades, and I can have summaries on the monthly and annual performances in money with the aid of formulas in different worksheets.
I use the insert comment function to add the reasons why I entered into that position, and my exit plans, if any.
Put down in words
By writing in words, together with recording in numbers, we get to use both sides of our brain.
You’ll be surprised what little lies you tell yourself when you review your diary/journal looking back.
The amount of detail to record is entirely up to your pleasure. Some may want to write a thesis on their positions, some just bullet points.
When I started out, I wrote under 3 sub-headings:
- The macro environment – Economic outlook, political situation, etc.
- The position itself – The reasons why I initiated this trading position. For core investment holding positions, I also add how I go about building a sizable position. All in or scaling in, for eg.
- My mental state – Whether I am sanguine, nonchalant, stressed, angry, happy. How I was feeling that day when I made the trade/investment.
That was then.
Now I don’t need to write on my mental state anymore. If I not in an optimum frame of mind, I stay out of the market. And my writings are now shortened to a few key words as memory aid. But that’s after many years of self-reflections and review.
It’s like adjusting the radio. Your turn left, turn right, and finally turn a bit left again. Optimum! So don’t worry if you find yourself writing too much or too little in the beginning. You’ll know the right level of detail for yourself soon enough!
As an investor, even if you hardly make any trades in a year, if you review your portfolio every quarter or half-yearly, you can record down your thoughts during these periodic reviews. For example:
Why are you not trimming your positions when some of the reasons you have bought have started to deteriorate?
Why are you not adding to positions when market is offering your same positions at a much lower price?
It’s no magic bullet
Depending on how honest you want to be to yourself, looking back at your own trades and positions, you can better see your strengths and weaknesses.
And to focus on your strengths or weaknesses is again up to you ;)
It’s sort of like putting muscles and flesh to the numbers skeletons we are so fond of.
Soon, you will be your own cheerleader and aunt agony :)
Trading and Investing is not a group adventure.
