The hyphen is not a grammatical slip -up, although I know there is the odd typo in my output; I like to think it puts me in the same category as The Grauniad.

I am referring to the notion of fighting those human psychological processes generally called ‘biases’. A very good fund manager at Jupiter Asset Management (he has just taken over one of Neil Woodford’s old mandates) once said he spent his working days fighting his human biases so that he would stick to his logical and tested investment training, experience and processes.
Common traits, as they have been called in a less academic way for many years and in many contexts of life, can trip up investors at all levels of experience and expertise. I have a T-shirt with the this quote from Mark Twain on it: ” When you find yourself in the majority, it is time to stop and think”.
The point is not that the majority are always wrong or that being a contrarian is a badge of good judgement, but that it is easier to ‘go along with the crowd’ so one ought to ask why are the crowd thinking that way and do we agree with it if we think objectively. The biases that drive the majority view may be many and varied and that is beyond the scope of this post (for a good introduction, search ‘Thinking Fast and Slow’).
A topical example for investors might be Tesla shares, which on any logical or intellectual basis are priced so that the slightest of upsets would result in very large losses for investors, yet professionals are still recommending purchases. In this case the main bias that makes you think you ought to join in the party is the FOMO one – the fear of missing out.
If you were asked ‘would you buy an investment that could lose 40% or more in a few days?’, I am petty sure you would say no, so objectively, you are not going to buy Tesla shares. But you may still wish you had. That is another aspect – the issue of regret.
I have one piece of advice for all investors. It is encapsulated in my guide to investing by way of a proper process and covers the early stages: know your objectives and how much you can afford to lose (your capacity for loss). After you have invested, when you are conducting reviews and when you are tempted to buy something, always run through those steps before letting the biases get the better of you! Un-bias yourself!
