OKLO stock surged 11.31% to $39.65 on Thursday, driven by a favorable policy development for the energy sector. The House passed the Ratepayers Protection Act, which shifts the financial burden of power grid upgrades from consumers to large data center operators. This move has sparked a rally in nuclear energy stocks, with OKLO benefiting from the broader thematic momentum.

What Happened

The House vote on Wednesday marked a pivotal shift in energy cost allocation, aiming to make data centers bear more of the grid costs associated with their electricity demand. This development has been interpreted as a positive signal for companies involved in nuclear power and related infrastructure. OKLO, which designs and builds advanced nuclear fission reactors, saw its stock rise in response to the policy shift. The stock closed at $39.65, up from $35.63 the previous session. NuScale Power, another nuclear energy firm, also gained nearly 9%. The broader market context showed a Nasdaq 100 rally and a retreat in oil prices, which may have contributed to a more favorable risk environment for speculative names like OKLO.

What The Data Shows

OKLO’s recent price trend has been volatile, with the stock declining 12.6% over the past eight sessions. Despite the current rally, the stock remains well below its 52-week high of $193.84. The company has a market cap of $6.7 billion but remains unprofitable, with a trailing twelve-month EPS of -0.93. Over the last 90 days, insiders have sold a total of $42.7 million in shares, with the most recent filing on September 15. Retail interest has been minimal, with only one Reddit post mentioning the stock in the past week.

What To Watch

The company does not have an upcoming earnings date listed. Investors should monitor the breadth of coverage and sentiment shifts as the nuclear energy theme evolves.
