London stock markets have a glaring loophole. If you own a minority stake, you can still hijack a company if voter apathy runs high. That structural vulnerability is now taking center stage as high-profile investment vehicles find themselves under siege from aggressive US activist funds.
Tom Burnet, chair of the Baillie Gifford US Growth Trust—an investment vehicle famously holding shares in Elon Musk’s SpaceX—has officially urged UK ministers to overhaul the City's regulatory rulebook. Why? Because a hostile campaign led by New York-based activist fund Saba Capital threatens to upend boards against the explicit wishes of the broader shareholder base. When rules permit minority factions to seize control through sheer low voter turnout, systemic reform isn't just an option. It's an urgent necessity.
The Mechanics of a Corporate Ambush
How does an activist fund capture an investment trust without majority backing? The math is brutally simple. In many corporate votes, apathy is the default state for everyday retail investors and smaller institutions.
Saba Capital has built a substantial stake in the trust, alongside fellow New York hedge fund Sessa Capital, which holds a notable 7.7% position. Burnet pointed out in his ministerial appeal that with roughly 30% of the company's shares locked down, Saba stands to win at the upcoming annual general meeting unless more than 38% of all other voting-eligible shares actively oppose them.
That threshold reveals a glaring flaw. A determined minority can easily overpower a majority who prefer the status quo simply because ordinary savers rarely fill out proxy voting forms. It transforms corporate governance into an attendance game rather than a true democratic consensus.
Why This Threatens London's Capital Markets
The UK government wants to revitalize London's public equity markets. Ministers want more high-growth tech companies to list locally, and they want ordinary savers to build wealth through accessible investment trusts.
Yet, those exact policy ambitions hit a brick wall when minority activist tactics go unchecked. If everyday investors believe their capital can be commandeered overnight by aggressive hedge funds exploiting loophole-ridden voting dynamics, they will pull their money out. Confidence evaporates fast when the system rewards aggressive corner-cutting rather than long-term value creation.
Boardrooms across the UK are watching this battle closely. If the Baillie Gifford US Growth Trust falls under minority pressure without regulatory intervention, open season begins for other vulnerable London-listed trusts.
What Needs to Change
Fixing this mess requires more than corporate PR statements or temporary defensive maneuvering. Regulators and lawmakers must rethink how proxy voting handles low-turnout environments.
- Modernize Proxy Systems: Make voting frictionless for retail investors so apathy doesn't automatically hand victory to activist funds.
- Raise Thresholds for Control: Require higher supermajorities or mandatory minimum participation rates from independent shareholders before activist board nominations can take effect.
- Close Minority Loopholes: Ensure that funds holding blocking stakes cannot bypass the collective intent of the broader investor registry.
The status quo benefits only those who know how to exploit procedural blind spots. Ministers must decide whether they want a thriving public market built for long-term investors or a playground for aggressive short-term arbitrage.
