The Marathon and the Sprint

Over the last few months, I’ve had a few messages from subscribers asking how I think about risk.

Not just the risk in individual AIM positions, but the bigger question:

Is this my whole investment strategy?

Fair question.

Because if all you see is the Small Caps. Big Bags. ISA, it probably looks like I’m taking a lot of risk.

I’m not.

My ISA is only one part of my overall plan.

My pension is the three-decade marathon.
My ISA is the five-to-ten-year sprint.

The difference changes how I allocate capital, how I think about risk, the time horizon I’m working to, and what I expect each account to do.

My pension does not need to be complicated or generate “alpha”. It just needs to give me a high degree of certainty that, over time, it will get me where I need to be.

My ISA on the other hand, is actively managed, and high conviction. I’m looking to own a handful of UK small-cap names, usually below £50m market cap, and take concentrated bets that have the potential to provide the kind of asymmetric returns a tracker fund is never going to deliver.

One account is for steady long-term wealth accumulation. The other for medium term wealth acceleration.

🔓 Access and Tax Efficiency Matter Too

The split is not just about risk. It’s also about access, tax and flexibility.

The ISA gives me total flexibility. I can take money out at any age, whenever I need it. The investments can grow free from income and capital gains tax, and withdrawals are tax-free too. Which is important if I’m going to bring financial independence forward.

The pension gives me tax relief on the way in and lets the money compound inside tax free like the ISA, but the trade-off is access and taxation on the way out. For most people, private pension access is currently 55, rising to 57 from April 2028.

When pension money is withdrawn, 25% can usually be taken tax-free, subject to the lump sum allowance. The rest is taxed as income at whatever income tax rate applies at the time.

That is why diversifying across wrappers matters too.

The pension gives me upfront tax relief and long-term retirement compounding. But restricts access to later on in life.

The ISA gives me flexible, tax-free withdrawals and access to the money whenever I might need it.

Before thinking about a normal investment account, you should always look to make proper use of both.

No friction to tax means your returns compound quicker, and the two wrappers complement each other.

⏳ The Marathon

I’ve got roughly 28 years until traditional retirement age. So the job of the pension is pretty simple:

Steady contributions. Global equity exposure. Always fully invested. Low costs. Time. No Stress.

The number I am working towards is £5,000 a month. Enough to provide me with a comfortable and dignified retirement income that increases with inflation and that I won’t outlive.

If you don’t happen to know how much you might need in retirement then a good resource to check is the retirement living standards tool here to give you a guide.

To turn that into a rough financial freedom number, I use the 4% withdrawal rule.

Monthly income target × 300 = Financial freedom number

For me that’s:

£5,000 × 300 = £1,500,000

I do not think of that as a target for one account. It is a rough total target across the whole plan — pension, ISA, investments, and potentially other income-producing assets (property, bonds etc)

Not a guarantee — just a useful figure to aim for.

With one adjustment worth making if you are in the UK: the State Pension.

For 2026/27, the full new State Pension is £241.30 per week — roughly £12,547 a year, or just over £1,000 a month. Your actual amount depends on your NI record, which you can check at GOV.UK.

If the State Pension is covering roughly £1,000 a month, the portfolio now does not need to generate the full £5,000. Just the shortfall:

Target monthly income: £5,000
Less State Pension: ~£1,000
Portfolio shortfall: £4,000
Freedom number: £4,000 × 300 = £1,200,000

That one adjustment cuts the required pot by £300,000.

But still a big number.

My approach is simple: contribute enough each month to give myself a realistic chance of achieving that long-term outcome.

For me that’s £500 net per month, with £250 tax relief on top — a 66.7% uplift before a single day of market growth, on money I will not touch for at least 28 years.

Not exciting. Just good financial planning.

And it gives me the freedom to go further out on the risk curve in my ISA. In pursuit of higher returns.

🏁 The Sprint

The ISA is the sprint — but not in the “get-rich-quick” sense.

Because that is not really a thing.

Building wealth is hard. It takes time, risk, patience, and the ability to absorb setbacks. It rarely happens in a straight line, and you will make mistakes along the way. I don’t know anyone who has done it “quickly” without either extraordinary luck or extraordinary skill. Probably both are needed.

My ISA time horizon is still 5–10 years. That is short compared to a pension, but long enough for fundamentals, turnarounds, and market re-ratings to actually play out.

The job of the ISA is just as clear, even if the strategy is very different:

As much as I can reasonably put away. High-conviction bets. UK-only. Small and micro-cap companies.

Once the pension contribution is taken care of, that is where I want my spare capital going.

The mandate is narrow as this is where I feel I have the biggest edge: UK-listed small and micro-caps, usually in the £10m–£50m market cap range, where the market is often thin, coverage is limited, and mispricing can be more extreme.

The goal is to test whether I can accelerate the path to financial independence through selective, concentrated risk taking. That means accepting volatility and the genuine possibility of being wrong, but only where the upside justifies the downside.

Could the ISA take serious hits? Yes.

Would that hurt? Obviously.

Would it blow up the long-term retirement plan? No.

That is the whole point.

Why the Split Matters

This is why I do not lump the two accounts together in my head.

The pension is there to do the heavy lifting over time.

The ISA is there to see if I can bring the timeline forward.

That is why I am comfortable keeping the pension boring and taking more concentrated bets in my ISA.

📊 Why AIM?

The UK small-cap market — AIM especially — is one of the most ignored corners of investing.

Brokers do not spend much time on it.

Institutional analysts cover it poorly, if at all and not independently.

Bulletin boards are full of rampers with their own agendas.

Fund managers cannot build meaningful positions even when they want to — the stocks are too small, too illiquid, or too awkward to own at scale.

So there are good businesses that get overlooked and for me, that’s the whole point.

That does not mean these are ALL good businesses — the majority are NOT.

But it does mean there are periods of mispricing. And mispricing creates opportunity.

Where there is no coverage, there is usually no consensus. And where there is no consensus, the market often gets the price wrong.

That gap is where I want to operate.

Take Inspiration Healthcare, LON:IHC, as an example.

When I started building the position at 13.18p, it was a neonatal ventilator business with a strong brand, an active CEO turnaround in progress, and a potential FDA catalyst in H1 2027.

It was trading at 0.29x sales.

That is the kind of setup I am looking for. A business the market has written off, where my own research suggests the market is wrong.

I started with 50,000 shares. Eventually, the market started to reassess it.

At the time of writing in May 2026, it was trading at 30p and became my first one-bagger of 2026.

That is the aim: find them before the market cares, size them sensibly, and give the thesis time to work.

📌 Why 10% Is Enough for One Job, But Not the Other

Conventional wisdom you read online is buy the index. Add regularly. Compound at 8–10% over decades. Let time do the heavy lifting.

That is a good plan.

For most people, it is probably the best plan. It is certainly the easiest, lowest-maintenance and least stressful.

I am not arguing against indexing. I use it myself for my pension, long-term steady compounding.

But the ISA’s role is to shortcut the journey to traditional financial independence.

10% is enough for the marathon. But it’s not enough for the sprint.

Let’s consider an investor who maxes out a £20,000 ISA allowance every year.

Illustrative only — not a realistic base case. Assumes £20,000 is contributed at the start of each year.

At 10% annual returns, reaching £1m takes around 18 years and £360,000 of personal contributions.

To reach £1m in 10 years, the required return rises to approximately 28.2% per year, with £200,000 contributed.

The 100% row is deliberately extreme. I am not treating 100% annual portfolio returns as realistic. That would be fantasy.

Nobody compounds at that rate year after year without extreme risk, luck, timing, skill, or some combination of all four.

But individual small-cap positions can produce 100%, 200%, 500% or more. I have seen that first-hand in the ISA.

And when those returns arrive early, in meaningful size, the compounding curve changes completely.

And there’s an opportunity cost of not taking higher levels of risk, especially during strong bull market phases as you are missing out on the opportunity to compound your capital more quickly. These opportunities are not always available.

A 3x or 5x early in the journey does not just improve the portfolio. It changes the capital base that every future return compounds on top of.

That is why early high returns matter more than most people realise — and why there is a real cost to being too conservative in the years when your runway is longest.

That is why I focus on small caps.

Because combined with sensible bet sizing and strict risk management portfolio returns can be transformational.

🔒 Risk Is Not the Same as Volatility

Volatility is the price moving around.

Risk is owning something without really understanding why you own it: what could go wrong, what would make you sell, and how it fits into the wider plan.

My ISA approach sits somewhere between fundamental investing, catalyst-driven trading, and venture-style betting.

The business still comes first, but timing matters too.

I look at charts. Not because I think a chart tells you everything about a business, but because you can be right on the company and still buy it at the wrong time.

“You can be right on the company and still buy it at the wrong time.”

The fundamentals tell me whether I want to own the business.

The chart helps me think about timing, sentiment, price action, and whether the market might be starting to change its mind.

I’m less concerned about what the company has done up until this point and more so looking forward over the next 6–12 months for a catalyst for the market to reassess the company. That could come from earnings, contract wins, operational progress, balance sheet repair, insider buying, technical strength, or a broader sector re-rating.

The venture-style element is in the return profile.

In a concentrated small-cap portfolio, a few winners will probably drive most of the return. But that only works if the losers are controlled.

So process matters.

Position sizing matters.

Cutting losses early matters.

And making sure the best ideas are big enough to actually move the needle matters too. It’s hard to find multibaggers so when you do, you need to make it count!

That is what I cover properly in Part 2: the risk/reward maths, position sizing, cutting losses, and how I think about letting winners become big enough to matter.
