Growing anxieties about a potential artificial intelligence (AI) bubble are prompting UK investors to re-evaluate their portfolios, especially after a recent dip in major US tech indices. The Nasdaq 100, a significant benchmark for US big tech, reached an all-time high of 30,730 on 3 June 2026, but subsequently fell by 4.6% over the following month. This downturn has intensified fears that the substantial investments poured into AI infrastructure might not yield the expected returns, with some tech companies now reportedly issuing debt to fund their AI operations rather than relying solely on robust cash flows.
Annabel Brodie-Smith, communications director of the Association of Investment Companies (AIC), highlighted the shifting sentiment, noting, "It’s understandable that some investors are looking to diversify their portfolios away from the AI boom and many investment trusts offer a great opportunity to do this." Many passive investments held by UK savers are heavily exposed to the large tech stocks that dominate indices like the Nasdaq 100 and the S&P 500, leading to a high concentration risk. Saftar Sarwar, Chief Investment Officer at Binary Capital, warned that a 'diversified' global portfolio is often not truly diversified, with just five companies accounting for around 30% of the S&P 500.
For those seeking to reduce their AI exposure, experts suggest looking beyond the 'obvious emerging markets' such as Korea and Taiwan, which have become significant technology-exposed equity markets themselves. Instead, 'emerging frontier markets' like Poland, Egypt, and Turkey are recommended, with BlackRock Frontiers Investment Trust (LON:BRFI) cited for its 52% weighting towards financials. Tomiko Evans, Chief Investment Officer at Crossing Point Investment Management, also pointed to European stocks as a diversification avenue, offering a broader mix of companies across sectors including industrials, financials, healthcare, consumer goods, and infrastructure. JPMorgan European Growth & Income (LON:JEGI) was mentioned as an interesting option in this space.
Both Evans and Sarwar see significant potential in UK equities for investors looking to step away from the AI theme. UK stocks have been considered undervalued for a decade, precisely because of their minimal AI and technology exposure, which now presents an advantage. Investment trusts such as Merchants Trust (LON:MRCH), City of London (LON:CTY), and Law Debenture (LON:LWDB) are highlighted for their focus on UK value or traditional equities, offering dividend yields typically around 3% to 4%. Temple Bar Investment Trust (LON:TMPL) and Murray Income Trust (LON:MUT) were also noted for their value discipline, UK weighting, and ability to generate sustainable dividends with limited direct technology exposure.
This drive for diversification comes as the Bank of England continues to monitor economic conditions, with any significant shifts in global tech investment sentiment potentially influencing the UK's financial markets. While specific FTSE 100 impacts from this exact trend are not yet fully clear, a broader move away from concentrated tech holdings could see renewed interest in more traditional, dividend-paying UK companies, potentially offering stability for UK investors seeking refuge from tech volatility. However, investors should always consult a qualified financial adviser before making any investment decisions.
