Rolls-Royce Holdings (LON: RR.) shares have extended their recent decline, slipping to around 1,455p, their lowest level since late July. The stock has now retreated roughly 9% from its August peak of 1,586p, as a combination of valuation worries, geopolitical tensions, and weakness in the small modular reactor (SMR) sector weigh on investor sentiment.

Valuation and SMR sector headwinds

The recent sell-off comes amid broader concerns about the company's valuation. With a market capitalization exceeding £120 billion, Rolls-Royce trades at a forward price-to-earnings ratio of approximately 33, well above the sector median of 20 and higher than peers such as GE Aerospace. This premium valuation has made the stock vulnerable to profit-taking, especially as the SMR industry faces a reality check.

Investors have grown cautious about the SMR space, with several key players experiencing sharp declines. Oklo has dropped to $38.5, down 80% from its October high, while NuScale Power has fallen to $9.21 from a record $57.23. Nano Nuclear Energy and MWX have also seen significant losses. Rolls-Royce, a major SMR player with government deals in the UK and Sweden, is not immune to this sector-wide sentiment shift. Although these contracts are substantial, the timeline for free cash flow positivity remains uncertain, adding to investor unease.

Fundamentals remain solid

Despite the share price weakness, Rolls-Royce's underlying business performance has been robust. In the first half of the year, revenue surged 26% year-on-year to £11.27 billion, with gross margin expanding from 28.4% to 30.1%. Operating profit jumped 46% to £2.53 billion, driven by strength across all three core divisions.

The aerospace segment saw engine deliveries rise 18% to 279 units, contributing to a 29% revenue increase to £6.1 billion. Defense revenue climbed 17% to £2.48 billion, while the power systems division generated £2.6 billion, up 28% from the prior year. These results underscore the company's operational momentum, even as market sentiment turns cautious.

Technical outlook: further downside possible

From a technical perspective, the daily chart shows Rolls-Royce shares breaking below a descending channel and falling beneath the key support level of 1,503p, which had been the highest point in July. The stock has also slipped below its 25-day exponential moving average, signaling bearish momentum.

Analysts suggest the next major support lies at 1,330p, a level seen in July. A move to that area would represent an additional 8.8% decline from current prices. However, some market participants believe the long-term uptrend remains intact, with a potential recovery toward 2,000p later this year if the stock stabilizes.

Investors are also keeping an eye on broader market signals, such as labor market data and gold's recent surge, which could influence risk appetite. For those tracking Rolls-Royce, the stock's valuation and SMR exposure remain key watchpoints, as highlighted in a recent analysis.

While the company's fundamentals are strong, the current pullback reflects a market recalibrating expectations. Whether the stock finds support at 1,330p or resumes its climb will depend on broader market conditions and investor sentiment toward the SMR sector.
