Over the last decade, the FTSE 100 has delivered a 6% return, compared to 8% for the Stoxx 50 and 13% for the S&P 500. This underperformance is attributed to weak earnings, domestic political upheavals, and the lack of a large listed technology sector, according to Goldman Sachs. Despite this, UK stocks have outperformed several major asset classes and equity markets globally this year due to low valuations, good dividend yields, and reduced concerns around concentration risk. Sentiment towards the UK market is improving, with increasing investor interest, although the pipeline of new companies requires urgent attention, warns fund manager Mark Slater.
