New Gold saw its share prices surge by 6.87 percent on Tuesday to close at $4.2 apiece as investors loaded positions following another round of rally in the prices of gold.

While it acknowledged the difficult demand environment amid the global trade and tariff uncertainties, Celanese Corporation (NYSE:CE) said that its global production network provides flexibility to manage most of the direct cost impacts of the current tariff conditions.

“Due to our mitigation preparations, we don’t anticipate direct tariff impact in the second quarter. We expect tailwinds as several non-recurring items from the first quarter do not repeat,” said Celanese Corporation (NYSE:CE) President and CEO Scott Richardson.

6. Constellation Energy Corporation (NASDAQ:CEG)

According to a report by Reuters, Constellation Energy Corporation (NASDAQ:CEG) is increasingly focused on data center projects connected to the grid as it aims to take advantage of the continued demand for electricity from AI data centers.

5. Oklo Inc. (NYSE:OKLO)

Oklo Inc. grew its share prices by 12.52 percent on Tuesday to close at $28.66 apiece as investors snapped up shares following news that the White House was planning an executive action to ramp up the deployment of nuclear reactors.

According to a report by Axios, one or more orders will likely heavily depend on the Energy and Defense departments to bypass traditional licensing delays from the Nuclear Regulatory Commission, in a bid to meet the soaring energy demand.

Citing multiple sources, Axios said that the Department of Defense could play a “key enabler” role due to its substantial energy needs and capacity to absorb regulatory risk.

If proven true, the initiative will provide a boost to Oklo Inc.’s (NYSE:OKLO) business, especially as it eyes clinching more deals following the resignation of OpenAI CEO Sam Altman as chairman of the nuclear technology firm.

It can be recalled that Altman reduced his ownership in Oklo Inc. (NYSE:OKLO) and stepped down from his chairmanship earlier last month to avoid any conflict of interest with potential partners.
