The London Stock Exchange has witnessed a significant outflow of companies in recent times, with a total of £95 billion worth of businesses leaving the exchange so far this year. This trend is driven by a combination of acquisitions and listings moving overseas, leading experts to express concerns about the future of the UK market. The departure of companies from the London market has been attributed to various factors, including relatively low valuations compared to other exchanges, such as New York. Some of the notable companies that have exited or are considering leaving include Anglo American, DS Smith, and potentially Shell. This exodus has raised concerns among city experts, who fear that the London market is losing its competitiveness and attractiveness to investors. As a result, there have been calls for measures to restore the competitiveness of the London market, such as removing stamp duty, reforming pensions, and introducing a British ISA.
