I am interested in psychology because I am interested in human behaviour, not just as it impacts on investments, but with all its joys and horrors.
There is a clear overlap between neurology and psychology and I have read that neurologists can agree with the idea that over time, our brains get programmed with biases, or ways of making decisions that are based on sub-conscious training of the process by past experience and maybe even inherited ‘coding’ of parts of our brains.

This is very relevant for investors who cannot avoid looking at the past when deciding how to position their investments for the future. If the past (insofar as we are aware of it) does not include any similar patterns to a developing situation, when that situation finally develops, we will be caught out – what has been called a ‘black swan’ event.
I think that where we are now with stock markets is actually a very white swan event. I have seen those birds ever since I was a little boy!
If one refers to the financial pages of newspapers and even web sites (which look oddly archaic) from 1999 – now a simple task thanks to Google, they read like they were written yesterday. What followed?
In March 1999, the NASDAQ peaked, then a whole series of events which were spread out over a whole year undermined the false and in some cases crooked (Worldcom and Enron, you may recall) valuations of many businesses. In the end, the NASAQ fell by around 75% – yes 75%! Other markets fell from the knock on effects and investors had to wait some 2 to 3 years to start making money again.
I read that in the second quarter of 2020 there were large net inflows into UK operated mutual funds (OEICs), with the exception of funds actually invested in the UK, which had outflows. Bond funds, index trackers and SRI funds all had positive flows of investor money. This was described in the article I read as ‘bargain hunting’.
If you want to see how history repeats itself, Google an article published by money.cnn.com called ‘Investing: 2000 and beyond’ and compare it with what pundits are saying now. Then check out what happened next to markets. You will find other articles if you have the time, referring to bargain hunters and new paradigms.
You will perhaps smile at the concluding advice in the CNN piece that US investors ought to reduce their market exposure to only 80% US and risk a whopping 20% elsewhere! In 1999, most UK investors would have adopted a similar stance and been heavily biased to their home market. If they were still doing that now, it would have cost them very dear.
I decided to write this post about the similarities with 1999 based on my own experience and memory, but notice while researching the history that many others, including academic writers, have seen the same swan sailing across the lake.
We can’t know that history will repeat itself, but they say that a fool is a person who repeatedly carries out the same actions and expects a different result. Maybe this time it will be different but do you want to risk it?
