X-Energy, Inc. shares rose approximately 3% in pre-market trading on June 29, 2026. The move followed the announcement of the company's inclusion in the Russell 1000 Value Benchmark (RLV).

The RLV tracks large-cap and mid-cap U.S. companies considered undervalued based on metrics like price-to-book ratios. This inclusion often increases demand from institutional investors and index funds, potentially boosting liquidity.

TD Cowen recently designated X-Energy as its top small/mid-cap idea for 2026. The firm maintained a Buy rating and a $35 price target. Analysts cited a recent overdone pullback in the stock price as a key factor for the recommendation.
