UK hedge funds long-short bets

Highlights

Burnham's plan to remove sales tax from household electricity heightens political and regulatory scrutiny on utility companies, increasing investor bearishness in the sector.
Burnham's pledge to expand public housing and tackle affordability is making homebuilders a prime focus for both long and short bets among investors.

Policy shifts open sector trade ideas

As reported by CNBC, hedge funds and other investors see Burnham's first policy moves as a catalyst for both negative and positive bets in UK stocks, after disclosed short positions in companies with at least 5% of shares sold short rose to 27 in the first half of 2026 from five a year earlier.

Burnham takes office this week promising a “cost-of-living government” and a new economic model for Britain. In his inaugural speech on Monday, he sets out a 10-year plan to reindustrialize the country, with housing costs and utility affordability emerging as early priorities.

Investors say that kind of domestic policy overhaul can widen dispersion within sectors, supporting relative value strategies that buy companies expected to benefit while shorting weaker peers. Alyx Wood, chief investment officer of Kernow Asset Management, says the current environment is producing more winners and losers, creating conditions that suit hedge fund trading strategies.

Utilities and housing draw investor focus

Energy and utility stocks are moving into sharper focus after Burnham announces on Tuesday plans to remove sales tax from household electricity to give customers breathing space from cost-of-living pressure. Investors say the move increases political attention on affordability and on the financial and regulatory pressures facing providers.

Wood says Kernow is bearish on UK utilities, pointing to high leverage at some companies, regulatory, operational and licensing strains, and the large investment needed in Britain's water and power infrastructure. She says utilities, often seen as defensive holdings in uncertain periods, are now the area where the firm is most negative because of weak water infrastructure, unmet consumer expectations and rising political scrutiny.

Housing is also emerging as a key area for stock selection. Burnham says he wants to expand public housing and end rough sleeping in the UK, and investors say a policy push to address housing affordability could produce both beneficiaries and underperformers among homebuilders.

Burnham’s renewed push for a land-value tax has brought the UK housing tax debate back to the forefront, with markets weighing how such a shift could affect house prices—especially in London and the southeast. Our publication previously noted that while the idea draws support across ideological lines, it remains hard to price in due to limited modern, large-scale precedents.
