As issues stand, I’ve 12 holdings from the FTSE 100 in my Stocks and Shares ISA. Some of those I’ve held for years, whereas a pair are newer positions initiated this yr.

In no specific order, they’re HSBC, AstraZeneca, Games Workshop, 3i Group, Scottish Mortgage, BAE Systems, Aviva, Legal & General, Sage (new holding), LondonMetric Property (new holding), and Coca-Cola HBC.

As we will see, it is a fairly a motley group that spans varied sectors. I maintain Scottish Mortgage for development, Legal & General and LondonMetric purely for dividends, and Games Workshop for each.

However, eagle-eyed readers could have noticed that I solely talked about 11 share above. So, what’s the lacking one?

The greatest holding in my ISA in the present day is Rolls-Royce (LSE:RR). Since Tufan Erginbilgiç took over firstly of 2023, the engine maker’s share value has gone parabolic. Happy days.

Now, I ought to level out that Scottish Mortgage, Games Workshop, and Wise (listed in London however not in the FTSE 100) are bigger total holdings as a result of they’re additionally in my SIPP portfolio. And I’ve bigger US holdings, together with Axon Enterprise and Shopify.

However, Rolls-Royce has been an unimaginable performer since I initiated a starter place in mid-2023. I additionally topped up twice on dips in 2024 and 2025.

For the report, I had no concept the inventory would skyrocket as shortly because it has (no person actually did). But it’s bittersweet as a result of I did have an inkling this could possibly be an enormous winner over time.

In March 2023, for instance, I wrote that I assumed we “could possibly be in the foothills of a large multi-year turnaround in the [Rolls-Royce] share value“.

So, why didn’t I make investments extra money (even when I needed to trim or promote different holdings to take action)? This is the query I maintain asking myself.

Of course, I’m talking with the advantage of hindsight right here. Back in 2023, I’d have been delighted to see Rolls-Royce hit £12.50 per share by 2030 — it’s already there years forward of schedule!

Looking forward, I’m nonetheless bullish on the corporate’s future. It has a number of avenues for development (optionality), from increasing in defence to promoting and servicing many extra passenger jet engines and supplying merchandise for knowledge centre backup energy.

Then there are small modular reactors (SMRs), which could be factory-built and deployed at far decrease value than conventional nuclear crops. Earlier this week, Rolls signed a contract with Great British Energy to get cracking on three SMRs for (*100*), in North Wales.

This brings certainty to the UK SMR programme and differentiates our enterprise as the one SMR firm with a number of commitments in Europe — an preliminary three models at (*100*) and as much as six models in Czechia.

However, I’m additionally conscious that the inventory’s buying and selling at a sky-scraping 32 instances ahead earnings. At this valuation, any surprising slowdown in development might spark a sell-off. And the Middle East battle provides provide chain danger shifting ahead.

Over the subsequent decade although, I believe surging journey demand, the AI infrastructure buildout, rising defence spend, and SMRs will stay 4 highly effective investing themes.

Therefore, I’m very happy to maintain Rolls-Royce in my Stocks and Shares ISA.
