The Range Nuclear Renaissance ETF (NYSE: NUKZ) has emerged as one of the standout performers of 2025. Since the beginning of the year, the ETF has climbed 57.5%, trading at 65.86 dollars and hovering near its annual high. This rally reflects the renewed global appetite for nuclear energy, increasingly seen as a cornerstone solution to climate challenges and the need for reliable power supply. Governments in the United States, Europe, and Asia are moving ahead with new nuclear projects, incorporating advanced technologies such as small modular reactors (SMRs), a trend that strengthens investor confidence in the sector.

Roughly 43.65% of the fund’s assets are concentrated in its top ten holdings. Leading the pack is Cameco, with a 10.23% weight, one of the world’s largest uranium producers. Constellation Energy follows at 8.01%, a key U.S. supplier of nuclear-based electricity. GE Vernova and Centrus Energy together account for over 7%, both providing critical equipment and technologies to the industry. Innovative players such as Oklo and NuScale Power also feature prominently, focusing on the commercialization of small modular reactors. Rolls-Royce, best known for its aerospace operations, continues to expand its footprint in nuclear energy and plays a strategic role in the fund’s diversification. This blend of established incumbents and disruptive newcomers offers investors a broad exposure to both traditional supply chains and cutting-edge innovation.

From a sectoral perspective, NUKZ is highly concentrated. Industrials represent 50.29% of the assets, largely manufacturers of infrastructure and equipment. Utilities account for 30.99%, reflecting the significant weight of nuclear power providers. The energy sector adds another 14%, while basic materials and technology together make up less than 5%. Such concentration increases volatility but creates a direct correlation with nuclear industry performance and global investment cycles. For investors, this structure means strong alignment with nuclear development trends, though it comes at the cost of limited diversification compared to broader ETFs.

On the macro level, the ETF’s rally coincides with global regulatory and investment momentum. In Europe, France and the United Kingdom are ramping up projects to build and modernize reactors as part of decarbonization goals. In the U.S., federal programs and incentives are advancing to accelerate SMR development and improve project economics, directly benefiting American companies included in the fund. Meanwhile, China continues to pursue aggressive investment targets, aiming to expand nuclear capacity on a massive scale by the end of the decade. Together, these developments provide structural tailwinds for NUKZ’s holdings and reinforce the growth thesis underpinning the nuclear energy sector.
