Rolls-Royce (LSE: RR) shares lately hit one other all-time excessive, hovering above 1,100p (£11). This simply makes Rolls the best-performing FTSE 100 inventory over two (+427%), three (+1,210%), and 5 years (+1,152%).
As somebody who first invested at a a lot lower cost in 2023, I’m clearly over the moon. However this now begs the query, ought to I crystallise features and transfer onto pastures new? Right here’s how I’m serious about issues.
Progress engine
When assessing my development shares, I first ask whether or not the engine’s nonetheless purring. Whether it is, the enterprise would ideally be firing on all cylinders, scaling quick, and gaining momentum. If it’s spluttering, properly, I would think about promoting up.
Let me give a few easy examples to indicate what I imply.
In its Q1 2026 earnings, Nvidia reported year-on-year income development of 69% ($44.1bn), and expects about one other 50% improve in Q2 ($45bn). CEO Jensen Huang commented: “International locations world wide are recognising AI as important infrastructure — identical to electrical energy and the web — and Nvidia stands on the centre of this profound transformation.”
In the meantime, Shopify simply reported Q2 income development of 31% ($2.7bn). CFO Jeff Hoffmeister mentioned: “Retailers of each dimension — from first-time founders to international manufacturers — are selecting Shopify to develop their companies and their success is what’s driving our success.”
As we will see, these development engines are purring away properly. Each shares are booming.
However what about Rolls-Royce, the maker of high-quality engines? Properly, income grew by round 10.7% within the first half (£9.1bn), whereas underlying working revenue surged 50% to £1.7bn.
Full-year working revenue steerage was raised to £3.1bn-£3.2bn, and the mid-term goal of £3.6bn-£3.9bn was reaffirmed. However CEO Tufan Erginbilgic harassed that this goal is “a milestone, not a vacation spot, with substantial development prospects past the mid-term.”
Stepping again, I agree that Rolls-Royce has engaging long-term development alternatives throughout its enterprise. The core Civil Aerospace ought to profit from rising international journey, whereas Defence and Energy Programs are more likely to thrive as European army spending is ramped up over the subsequent decade.
Moreover, as Europe invests to hit Web Zero targets, the small modular reactor (SMR) alternative seems substantial. Giant synthetic intelligence (AI) knowledge centres could sooner or later want their very own SMRs. Rolls-Royce says this nascent enterprise can be worthwhile and free money move optimistic by 2030.
Contemplating dangers
Given all this, I see no motive to promote my shares. Nevertheless, there might be potential dangers which may persuade me to.
For instance, Rolls-Royce has repeatedly warned about provide chain challenges. These may throw a spanner within the works shifting ahead, particularly when the affect of President Trump’s tariffs probably kick in later this yr.
Additionally, a ridiculously excessive valuation may pressure me to take some chips off the desk. That’s as a result of Rolls may shortly turn out to be a sufferer of its personal success if development targets are missed, even modestly.
Based mostly on forecasts for 2026, the ahead price-to-earnings ratio right here’s round 36, falling to 32 by 2027. That’s fairly excessive for the FTSE 100 engine maker. A price-to-sales ratio of 4.7 additionally doesn’t precisely scream worth.
That mentioned, I don’t suppose the inventory’s ridiculously overvalued. My view is that Rolls may nonetheless go increased from right here.
Weighing issues up then, I’m holding on to my shares.
