Data Storage Stocks Jump as Iran Ceasefire Promises to Free Up Helium Market

Dow Jones04-08 20:36

By Nicholas G. Miller

Shares of data storage companies rose after the U.S. and Iran agreed to a ceasefire that promises to unlock supplies of helium, which is used in chip production.

Micron Technology jumped 9.3% in Wednesday's premarket trading. Sandisk rose 8.8%. Seagate increased 7.6%. Western Digital gained 6.8%.

The conflict in the Middle East had halted natural-gas exports from Qatar, the source of about a third of the world's helium.

That forced helium users to scramble for scarce short-term spot market cargoes, leading prices to more than double.

Chip makers use helium to maintain stable temperatures while etching silicon wafers into advanced semiconductors.
