2025 was a terrific year for many FTSE shares, with a host of companies maintaining their upward momentum into 2026. And over the last 12 months, some of the biggest UK winners include:
- Saga – up 353%.
- Goodwin – up 295%.
- Fresnillo – up 462%.
- Ceres Power Holdings – up 108%.
- OXB – up 105%.
But as all experienced investors know, just because a stock’s done well in the past, doesn’t mean it will continue to do so in the future. That’s why institutional analysts are busy hunting down new opportunities for investors to explore in 2026. And right now, the experts have highlighted two FTSE shares with impressive growth potential.
Communication is key
First on the list is Gamma Communications (LSE:GAMA). While often-overlooked, large-scale enterprises often continuously need to communicate both internally and externally. And with old-school phone lines being replaced with cloud telephony, Gamma’s positioned itself to be a leading player in the European unified communications-as-a-service (UCaaS) sector.
Subsequently, the business has evolved into a steady compounder over the years. But in 2025, Gamma shares came under notable pressure. With the firm still heavily reliant on the UK, softer economic conditions saw earnings stumble despite revenues continuing to climb.
This impact has only been amplified by fierce levels of competition from infrastructure incumbents like BT and Vodafone. But with the experts seeing this as a temporary cyclical slowdown, investors may have been a bit too zealous in their selling activity.
So much so that the team at Peel Hunt have recently reiterated a share price target of 1,820p. Compared to where the stock trades today, that represents a 99.7% potential capital gain if earnings momentum is restored – an opportunity worth exploring further.
Data & analytics
RELX (LSE:REL) is another FTSE share that’s seen its market-cap take a hit over the last 12 months, falling by almost 50%!
The business specialises in providing proprietary data access and AI tools used by a variety of businesses, governments, and enterprises. And in areas like scientific research, legal practices, and risk management, the company’s proven to be a mission-critical product for many customers.
However, with the rise of new AI models, investors are growing concerned that RELX’s business could be exposed to disruption. As such, despite the underlying fundamentals remaining impressive, shares of the data vendor have taken quite a beating.
Seeing such volatility isn’t entirely surprising. After all, RELX shares have long since traded at a premium valuation. Yet, the analysts at both Barclays and Morgan Stanley seem to think the market may be getting ahead of itself, issuing share price targets of 3,745p and 3,610p, respectively.
If those projections prove accurate and it’s able to avoid being disrupted by AI, then buying shares today could unlock a potential return of up to 74%!
That’s why, despite the risks, I think this is another FTSE stock worth investigating further in 2026.
