After years of underperformance, the UK stock market, particularly the FTSE 100, is regaining the attention of global investors. The FTSE 100 has gained nearly 10% year-to-date and is up almost 18% in dollar terms, marking its best dollar-denominated performance since 2009. This surpasses both the European STOXX 600 (up 7.5%) and even the S&P 500 (up 6%), helped by a stronger British pound and rising investor interest in undervalued UK equities. The FTSE's success is driven in part by its defensive composition: healthcare, utilities, and food retailers such as AstraZeneca and Tesco, combined with exposure to commodity sectors like energy and mining through companies like BP and Anglo American.

Valuations have long been a concern, with the UK stock market historically trading at a discount compared to global peers. However, that gap is narrowing. The FTSE 100 now trades at a 12-month forward price-to-earnings (P/E) ratio of 12.5, the highest in five years and close to the STOXX 600’s 14.1, its narrowest differential in 18 months. By contrast, the S&P 500 trades at a much higher P/E of 23. This valuation rebound, alongside structural improvements such as a potential UK-U.S. trade deal and regulatory reforms to boost London's capital markets, is shifting sentiment.

Foreign investors, including pension funds and wealth managers who had pulled back after Brexit, are returning. Yet, despite the improved market performance, challenges persist. Inflation in the UK remains above the Bank of England’s 2% target, and the broader economy faces stagnation with weakening business activity and job growth. Net investment outflows from UK equities reached $20 billion in 2025, though those outflows have slowed significantly in recent weeks. While optimism is returning, some analysts see the FTSE's outperformance as modest and driven more by currency strength than broad-based market fundamentals. Nonetheless, the market’s resilience and deep value continue to make it an increasingly attractive option for global investors.
