Why are UK shares doing so badly?

What is wrong with UK shares? While the US, European and Japanese stock markets reach new highs, UK markets are stuck in a deep rut. The FTSE 1000 is just 10 per cent higher than it was on the last day of last century. As for the FTSE 250, small cap and AIM markets – which seemed to be doing okay until 2021 – they are still deep in bear market territory. The AIM 100 – the largest hundred shares on the Alternative Investment Market, which peaked at over 6000 in August 2021 is currently down below 3600. That is the sort of crash that happened to the wider stock market after the dotcom boom and the 2008/09 financial crisis, but has gone unnoticed because it is not reflected in global markets. It can’t be that all UK companies are useless – the proof of that is that UK companies that have switched their listing from the UK to the US have enjoyed an instant surge.
