Our investment experts lift the lid on their Junior ISA fund picks…
Some parents may register their newborn for their alma mater before they’ve even left the hospital but a savvier first step might well be opening a Junior ISA.
Around two million children in the UK already hold one, with almost £10 billion squirrelled away tax-free. Most accounts sit below £25,000 but more than 50 lucky youngsters are already sitting on £200,000-plus nest eggs, according to Standard Life.
That might sound like an eye-watering sum but the potential is even greater: the annual allowance has risen from less than £4,000 at launch to £9,000 a year today. Max out your allowances and plump for the higher-octane returns of a stocks & shares JISA over cash, and compounding has nearly two decades to weave its magic.
Putting some numbers to it, contribute the full £9,000 every year from birth to 18, assume a 9.6% annual return (the average annual return for a stocks & shares ISA over the last 10 years according to Moneyfarm) and you’re looking at a pot of almost £500,000. Even £1,000 a year could grow to more than £50,000.
Whether you’d trust an 18-year-old with that many zeroes, however, may hinge on whether or not they’re inclined to save it wisely for a house deposit…or blow it all on a Vauxhall Corsa with questionable body kit.
The first decision is which platform to use and fees can have a surprisingly large impact. To help with this, we’ve published a guide to the best Junior ISA providers in the UK.
Next comes the fun part: what to invest in. With that in mind, we’ve asked some of our colleagues to reveal where they’ve invested their Junior ISAs.

I hope my children will use the proceeds of their JISAs for something useful and long lasting. University perhaps, or a deposit on a first flat? Either way, I have assumed that they won’t spend it all on their 18th birthday! The key is that my JISA investments are likely to have a mean timeframe of a decade but could be more.
I’ve long been a fan of trying to apply portfolio theory, which essentially uses diversification across different return drivers to deliver higher risk adjusted returns, as I set out in this article a few years ago. Aside from looking for exposure to private markets and other alternatives to maximise diversification, the other principal is that this needs to be a fire and forget approach, without the need to trade the portfolio – for time and cost reasons.
I think investment trusts are an excellent place to ‘fire and forget’ and to compound returns. A good example is the newly-merged Alliance Witan (ALW)which continues to provide a low cost, active global exposure and so I’ve been happy to continue to hold it. In my view, the reassurance that a board being on the front foot looking after the different nest eggs in the portfolio is very much worth it.
As a long-term investment trust follower, it is perhaps not surprising that the first JISA investment I made was AVI Global (AGT), which offers a global exposure but with the added kicker of the potential for underlying companies’ discounts narrowing. This trust has done very well for me over the years, and is the best performer in absolute terms. Overall, I have 42% in equity trusts, including Rockwood Strategic (RKW) which has grown into a meaningful position through strong performance.
Alternatives represent 18% of the portfolio, represented by BH Macro (BHMG)and Greencoat UK Wind (UKW), the latter of which has seen its discount widen dramatically since I bought it. It remains in the portfolio, not least because of the income it generates, but I also have confidence that over time share price returns will improve.
Elsewhere, I have c. 26% in private equity trusts, which is below the Yale model allocation, but meaningful enough to be a driver of long-term returns. Despite discounts currently at very wide levels, my holdings have delivered strong returns over the years. These include CT Private Equity (CTPE),HarbourVest Global Private Equity (HVPE)andOakley Capital Investments (OCI).
Finally, around 10% of the portfolio is made up of RIT Capital Partners (RCP)which encapsulates all that I think my JISA portfolio is trying to do, but currently trades on a discount of close to 30%.

It’s been a while since those fond days when my husband Peter and I were D.I.N.K.S “double income, no kids.” Back then, our biggest financial decision was whether to order takeaway or eat out. Nowadays, life is a whirlwind with our little ones Nina (6) and Axel (3), plus full-time jobs.
Thankfully, we’ve been investing into their Junior ISAs through a monthly savings plan since Nina was born, giving us a little peace of mind that one day they might fund their own coffee addiction or perhaps education. This felt like a natural decision, especially since we’ve been saving into our own ISAs for years and who doesn’t love a good tax break?
Although my professional focus is very much on alternatives, the core growth engine of both their portfolios is global equity index funds given their long term investment horizon. On top of that, I sprinkle in a few actively managed funds, like the Franklin Templeton Royce US Small Cap Opportunity Fund for US small-cap exposure and the Artemis UK Select Fund, which has outperformed both the index and its peers across all major time periods. There’s even a very small allocation to hedge funds for additional portfolio diversification.
Knowing that Axel and Nina’s futures are already getting a head start through their Junior ISAs makes the financial side of parenting a whole lot easier. It’s one less thing to stress about in the whirlwind of toddler tantrums and school projects and we can focus on what really matters.

As the only person in my family both aware of the long-term benefits of investing and in a financial position to do so, I wanted to help give my niece a head start, so I opened a Junior ISA.
It had been suggested that a Junior SIPP would be a better option as it would have a full 60-odd years to compound and there’s less of a temptation of withdrawing a big lump sum and spending it on something superfluous but if that’s really what she wants to do, then it’s her cash.
With her being a 21st century baby, we have a minimum of 14 more years to build up her pot. I chose Fidelity because they don’t charge a platform fee, but they do offer a broad range of funds from which to choose.
I decided to go passive for my fund choices because I’d rather not let any personal prejudices get in the way, but have some additions around the edges of a global stock market tracker. My brother’s one stipulation was no investments in Chinese companies.
Therefore, the main part of the portfolio is simply an investment into the Fidelity Index World fund, which has a low 0.12% OCF and gives exposure to large and mid-sized developed market stocks.
The bolt-ons revolve around eking out some extra returns, for which I’ve decided to go small- and mid-cap where possible. I would have plumped for Scottish Mortgage (SMT) as a good long-term compounder, but its 10% allocation to China makes it a no-go.
In the end, I’ve invested in the Vanguard Global Small-Cap Index fund, where the OCF again was lower than peers at 0.29%, and the Vanguard FTSE 250 UCITS ETF.

Both of us grew up understanding the value of education, so we’ve been very diligent in saving into a Junior ISA for our soon-to-be-3 year old son. Whilst there are arguably more flexible ways to invest for children, we like the discipline of a Junior ISA which will not only showcases the value of compounding but also provides a small step up for his future.
We make monthly contributions into his JISA and top it up with gifts from great-grandparents on birthdays, Christmases and “name-days”, as is tradition in our half-Finnish household. We have directed this into a couple of equity-based vehicles, which we hope to generate strong returns over the next 15 or so years. Given the long-term mindset, we’ve also felt liberated to select higher risk asset classes with the potential for higher returns over time.
Our first selection has been Polar Capital Biotechnology due to its very active stock selection with a small and mid-cap bias. It’s a sector with binary outcomes but the right manager can create exceptional alpha over the long-term. It also enjoys strong tailwinds from breakthrough treatments, the transformative potential of AI and ageing populations.
We’ve also invested in Landseer Global Artificial Intelligence, a global equities fund which uses AI to help identify firms that are using AI in their own activities to ultimately improve company performance. This isn’t focused purely on tech firms and actually has a relatively well diversified portfolio, without having to make a decision on which firm will ultimately win, as many of the leading players are yet to demonstrate profitability.
As our son’s investment pot grows, we hope to diversify further into other areas. Similarly, when he stops eating his own body weight in blueberries every day, we might well have the budget for it…

I’m a big fan of Junior ISAs. Not just for the tax-wrapper and superior returns to cash but as a way to spark an interest in investing (let’s hope we’re nurturing a generation of Warren Buffetts rather than Nick Leesons…).
We went with Hargreaves Lansdown for our Junior ISAs and my sons have relished the sibling rivalry of tracking their portfolios on the app. Admittedly, I felt a pang of sympathy for my eldest enduring his younger brother’s daily victory parade at the breakfast table, though that particular ritual mysteriously ended in late 2022. Nothing teaches risk and reward quite like watching your portfolio turn red.
One of the great virtues of Junior ISAs is the enforced long-term mindset: the money’s locked away until 18 so there’s no chance of an ill-advised splurge on limited-edition Pokemon cards or Air Jordans. Some of our early buys, Fundsmith Equity and Lindsell Train Global Equity, have since been sold but Fidelity Global Technology, Fidelity UK Smaller Companies and Sanlam (now Landseer) Artificial Intelligence have gone the distance. More recently, we’ve broadened into commodities with BlackRock World Mining (BRWM) and a WisdomTree Precious Metals ETF.
These days, though, I’m more spectator than manager. My eldest has bagged some recent winners with Vanquis, 3i Group and the Pictet Clean Energy Transition fund. True to second child contrariness, the younger Groves has put his shirt on a mixed bag with some chunky gains on Games Workshop (GAW) and an iShares Listed Private Equity ETF, offset by modest losses on BP (BP.) and CT American Smaller Companies.
Still, if it stops my children from mindlessly scrolling TikTok 24/7, I’ll take that as a win.
