The current composition of my Stocks and Shares ISA includes 12 holdings from the FTSE 100. Among these are long-term holdings as well as more recent additions. The notable shares are HSBC, AstraZeneca, Games Workshop, 3i Group, Scottish Mortgage, BAE Systems, Aviva, Legal & General, Sage, LondonMetric Property, and Coca-Cola HBC.
The largest holding in this portfolio is Rolls-Royce (LSE: RR). Under the leadership of Tufan Erginbilgiç since January 2023, the company’s stock has seen impressive gains. This performance is noteworthy, especially considering my initial investment in mid-2023, followed by additional purchases during market dips in 2024 and 2025.
Rolls-Royce: A Strong Performer in My ISA
Although I had anticipated potential growth, the speed and magnitude of the share price increase were unexpected. Back in March 2023, I noted the possibility of a substantial recovery for Rolls-Royce. Remarkably, the stock value has already reached projections I had set for 2030.
Looking forward, I remain optimistic about Rolls-Royce’s growth trajectory. The company has multiple growth avenues, including:
- Expansion in the defense sector
- Increased sales and servicing of passenger jet engines
- Supply products for data center backup power
- Development of small modular reactors (SMRs)
Recent Developments
A recent contract with Great British Energy to develop three SMRs at Wylfa, North Wales, highlights Rolls-Royce’s commitment to advancing its technology in Europe. This project distinguishes them as a leader in the SMR market, with initial commitments for three units in Wylfa and potential for six in Czechia.
However, I am aware that the stock currently trades at a high valuation of 32 times forward earnings. This heightens the risk of a sell-off due to any sudden downturn in growth. Additionally, geopolitical tensions in the Middle East could impact supply chains.
Future Outlook
Despite these concerns, I believe that several key factors will support ongoing investment in Rolls-Royce:
- Growing travel demand
- Expansion of AI infrastructure
- Increased defense spending
- Development of small modular reactors
Consequently, I am confident in retaining Rolls-Royce as a significant part of my Stocks and Shares ISA portfolio. This strategic decision reflects my belief in the company’s capacity to navigate future challenges and capitalize on emerging opportunities.
