Have you ever wondered what happens when one of your top investments suddenly skyrockets in value, but the rules of the game stop you from doubling down on that winner? That’s exactly the situation a lot of long-term investors in Scottish Mortgage are facing right now. This popular investment trust, known for backing some of the world’s most ambitious growth stories, is asking its shareholders for a modest but meaningful tweak to how it handles private companies.
It’s not every day that a fund with billions under management needs to adjust its own boundaries, but here we are. The proposal feels like a practical response to success rather than a desperate fix, and honestly, after watching how these things play out over the years, I think it’s a sensible step. Let’s unpack what’s going on and why it matters to anyone who cares about accessing tomorrow’s giants today.
A Flexible Approach to Tomorrow’s Giants
Scottish Mortgage has built its reputation on hunting exceptional companies—those rare businesses capable of transforming industries and delivering outsized returns over decades. Unlike many funds that stick strictly to listed stocks, this trust has never been afraid to venture into private territory. Some of its biggest wins have come from backing visionary founders long before Wall Street gets involved.
But private investments come with quirks. Shares don’t trade daily, so prices don’t fluctuate constantly. Valuations update sporadically—usually when new funding rounds happen or secondary sales occur. When a holding like that experiences explosive growth between those events, the percentage it represents in the portfolio can swell without anyone buying a single extra share.
Why the 30% Cap Exists in the First Place
Most investment trusts set guardrails around illiquid assets for good reason. Private companies carry higher risk: less transparency, longer time horizons, and genuine difficulty selling if you need cash. The current rule limits unlisted holdings to 30% of total assets, measured at the point of purchase. It’s a sensible precaution that keeps the portfolio from becoming too hard to trade or value accurately.
In practice, though, that hard cap can create awkward moments. Strong performance in existing private positions—combined with things like share buybacks or dips in public holdings—can push exposure above 30% without any new deals. Once that happens, managers are effectively blocked from adding to winners or jumping on fresh opportunities until the percentage drops back down.
Being patient, long-term partners to exceptional private companies as they scale is central to our approach. Market movements sometimes limit our ability to act when it counts most.
– Investment manager perspective
That sentiment captures the frustration perfectly. You spot something truly special, but your hands are tied by a rule that was never designed to penalize success.
The Heavy Hitters Driving the Conversation
Take a moment to consider the biggest private name in the portfolio. One space-exploration pioneer alone accounts for a significant chunk—around half—of the allowable private allocation on its own. Add in another major social-media platform owner, and together they eat up nearly two-thirds of the entire 30% bucket. When those valuations climb sharply, the math gets tight very quickly.
Recent secondary transactions and market chatter suggest these businesses could be worth considerably more in the near future. That’s fantastic news for existing shareholders, but it also illustrates how quickly the cap can become a constraint. It’s almost counterintuitive: doing well makes it harder to keep doing well.
- Private winners grow faster than public markets expect
- Valuations jump in lumps rather than smoothly
- Portfolio weight increases passively through revaluation
- New investments or follow-ons get blocked until rebalancing occurs
This dynamic isn’t unique to one trust, but it feels particularly acute here because the conviction in these names runs so deep.
The Proposed £250 Million Buffer Explained
The board isn’t asking to scrap the 30% rule. Instead, they’re suggesting a limited safety valve: the ability to invest up to an extra £250 million in private companies even when the headline limit is exceeded. That figure represents roughly 1.7% of current total assets—a small, controlled amount in the grand scheme.
Importantly, this extra capacity would come with strings attached. The board would have discretion to approve specific investments, and the whole arrangement would require shareholder approval every year starting in 2027. That annual renewal keeps governance tight and prevents any drift toward excessive illiquidity.
In my view, this strikes a reasonable balance. It acknowledges real-world portfolio mechanics without throwing caution to the wind. Managers could support existing holdings during key funding rounds or seize rare new opportunities without having to sell other positions prematurely.
Valuation Challenges: Why Private Assets Behave Differently
Let’s talk about why private valuations can feel so jumpy compared to their public counterparts. Public stocks adjust minute by minute based on supply, demand, news, sentiment—you name it. Private companies typically get re-priced only when they raise money or allow secondary liquidity events.
Between those moments, months or even years can pass. A lot changes in that time: revenue explodes, new products launch, competition shifts, macroeconomic conditions evolve. When the next pricing event arrives, the valuation often reflects all that accumulated progress in one big step.
That’s great when the step is upward, but it creates exactly the kind of passive overweighting that triggers the current policy constraint. One particularly high-profile example reportedly doubled its implied value in recent months. No wonder the trust’s private exposure climbed well beyond the original threshold.
| Factor | Public Companies | Private Companies |
| Pricing Frequency | Daily / Continuous | Infrequent (funding rounds) |
| Valuation Adjustments | Gradual, market-driven | Step changes, event-driven |
| Liquidity | High (exchange-traded) | Low (restricted) |
| Risk of Overweighting | Lower (easy to trim) | Higher (passive drift) |
This table highlights why a rigid percentage cap can sometimes work against investors rather than protect them.
Potential Benefits for Long-Term Shareholders
If the proposal passes, the trust gains breathing room to stay true to its philosophy. Being able to participate in follow-on rounds for proven winners can compound returns significantly. Early-stage conviction often pays off most when you can scale exposure thoughtfully rather than being forced to sit on the sidelines.
There’s also a psychological advantage. Knowing the team can act decisively when rare opportunities appear builds confidence. I’ve always believed that the best growth investors combine discipline with flexibility—too much rigidity can mean missing the next wave.
- Support existing high-conviction private holdings during growth phases
- Seize selective new private opportunities without forced sales elsewhere
- Maintain alignment with long-term growth mandate
- Limit overall risk through small buffer size and annual review
These points feel like practical enhancements rather than reckless expansion.
Risks and Considerations Worth Watching
Of course, no change is risk-free. More private exposure means more illiquidity, especially if public markets turn volatile. Valuations can also move downward—though that’s less of an issue for triggering the cap.
Shareholders should also think about the trust’s discount or premium to net asset value. Private assets can contribute to NAV uncertainty, which sometimes weighs on market sentiment. But if the extra capacity helps capture more upside, it could actually support a tighter discount over time.
Perhaps the most interesting aspect is the governance layer. Requiring annual shareholder votes on the buffer keeps everyone accountable. It prevents mission creep and forces regular debate about the right balance between public and private.
Flexibility to act in shareholders’ long-term interests while staying selective is the goal here.
That sums it up nicely. It’s not about going wild—it’s about not being handcuffed by yesterday’s rules when tomorrow’s opportunities arrive.
What Happens Next and How to Think About It
A general meeting is scheduled soon for shareholders to weigh in. If approved, the change takes effect immediately, with the first annual review coming at the following AGM. For everyday investors holding this trust, the decision comes down to trust in the process.
Do you believe the managers have the discipline to use a small extra allowance wisely? Are you comfortable with slightly higher private exposure in exchange for better access to transformative companies? These are fair questions.
In my experience following these kinds of proposals, they usually pass when the rationale is clear and the ask is modest. Here, both conditions seem met. The £250 million figure is deliberately conservative, and the annual renewal mechanism adds real accountability.
Broader Implications for Growth Investing
This moment reflects a larger trend. More high-quality companies are staying private longer, building massive scale before considering public markets. Traditional investors risk missing out unless they have vehicles that can participate early.
Investment trusts like this one offer a middle path: pooled access to private opportunities with daily liquidity for the overall fund. Adjusting policy to reflect that reality makes sense in a world where innovation cycles keep accelerating.
Whether you’re already invested or considering it, keep an eye on how this plays out. Small policy tweaks can sometimes unlock meaningful long-term value. And in growth investing, those compounding edges matter more than almost anything else.
One final thought: success breeds complexity. When your best ideas work spectacularly, the portfolio naturally evolves. Finding ways to accommodate that evolution without abandoning prudence is the art of managing a truly long-term growth mandate. This proposal feels like a thoughtful step in that direction.
The conversation around private investments in listed vehicles is far from over. As more trusts grapple with similar dynamics, expect to see creative—but careful—solutions emerge. For now, Scottish Mortgage is leading the way by asking for just enough room to keep doing what it does best.
