Making an attempt to construct a £1m portfolio with FTSE 100 shares may sound unrealistic — particularly with markets wobbling and headlines dominated by geopolitical pressure. However that framing misses the larger image.
The actual problem isn’t simply discovering the subsequent winner. Markets transfer in cycles, sentiment shifts rapidly, and even sturdy shares can go nowhere for lengthy intervals.
So if short-term value strikes can’t be relied on, what truly drives long-term wealth?
Sturdy moats
Sooner or later, each enterprise runs into disruption. Markets flip, prices rise, and demand weakens. However not all corporations reply in the identical manner.
The strongest are inclined to have one thing others don’t — sturdy aggressive benefits, sturdy money technology, and the monetary flexibility to maintain investing when rivals are compelled to tug again.
Actually, intervals of uncertainty can strengthen their place. Whereas weaker gamers retrench, these companies can take market share, develop their footprint, and emerge from the cycle in a stronger place than earlier than.
The query, then, isn’t what the market does subsequent — however which companies are positioned to return out of it stronger.
Spoilt for selection
In 2026, a variety of FTSE 100 enterprise fashions have been put to the check.
Nationwide Grid has confronted scrutiny over a rising debt load, but it continues to develop its regulated asset base, doubling down on long-term grid funding.
In the meantime, RELX has needed to take care of the rise of generative AI disrupting elements of its authorized and knowledge providers. Nevertheless it’s nonetheless investing closely in information, analytics, and platform capabilities.
Aviva: a unique type of insurer rising
For me, the standout alternative within the FTSE 100 proper now’s Aviva (LSE: AV.) It’s not as a result of the share value has surged. It’s as a result of the enterprise beneath it has modified.
On the floor, it nonetheless appears to be like like a big insurer. However the best way it’s now competing factors to one thing very totally different rising: a extra scalable, data-driven monetary platform quite than a standard cycle-dependent underwriter.
That shift has already been examined in observe. Rising claims prices and inflation uncovered weaker gamers throughout the sector, with Direct Line a transparent casualty. In contrast, disciplined underwriting — significantly tighter pricing and threat choice — allowed Aviva not solely to navigate the cycle, however to accumulate from a place of energy.
Scale now issues much less as a development driver and extra as a structural benefit that stabilises earnings by way of the cycle.
That benefit is bolstered by information and machine studying embedded throughout pricing and claims, with AI more and more positioned as a long-term lever for value effectivity.
On the identical time, a bigger multi-product buyer base reduces churn and improves the predictability of returns.
What’s the decision?
That is nonetheless a change in progress, not a completed story. The important thing threat is execution. If the anticipated advantages from scale, information, and AI take longer to feed by way of than administration assumes, then supply of focused earnings development over the subsequent three years may fall brief. That will possible weaken confidence in margin stability and money technology, and will weigh on sentiment.
That mentioned, sturdy companies usually evolve their fashions whereas sustaining earnings momentum. Markets don’t all the time value in that shift instantly.
For buyers searching for high-quality UK names that will nonetheless be underappreciated, that is one to look at carefully. The valuation could not but totally mirror the story.
