Where nuclear energy stocks stand now
As of 12 October 2026, Nuclear Energy (NLR) ranks #110 of the 115 groups Zensei tracks by one-month return against the S&P 500, among the market's weakest pockets. It is losing its lead. It built a 1.4-point advantage over the S&P 500 across the longer, time-shifted window, but over the past month it has slipped 13.5 points behind the market — the Cooling quadrant of the rotation map.
On the shorter tape, NLR's momentum is weakening: the intraday trend that carried the move is cooling across the shorter windows. NLR's relative-strength line has broken below its long-term average — the long-term outperformance trend is no longer intact. Both signals point the same direction here: the market is not rewarding this group on either horizon.
The exposure comes via VanEck Uranium+Nuclear Energy ETF, whose 26 tracked holdings are led by Constellation Energy Corp, Cameco Corp and Fortum OYJ. Weighted by portfolio, the fund's holdings trade at roughly 28.8× earnings. The thing to watch from here is whether this is a pause or a handoff: cooling groups sometimes reset and reclaim leadership, but a deepening one-month deficit usually means rotation has moved on.
