Atomera Incorporated ( ATOM ) shares are trading lower Thursday potentially continuing a momentum-driven decline as markets react to mixed inflation data for December.

What To Know: The data showed consumer prices rising 2.9% year-over-year, marking the highest annual rate since July 2024. The Consumer Price Index (CPI) increase, driven largely by a 2.6% rise in the energy index, has renewed concerns over the Federal Reserve’s ability to achieve its 2% inflation target.

While core inflation, excluding food and energy, rose 3.2% annually—slightly below estimates—monthly core prices climbed 0.2%, in line with expectations.

Market sentiment reflected optimism in equity indices, with S&P 500 futures up 1.5% and Nasdaq 100 contracts gaining 1.6%. However, Atomera ( ATOM ) shares diverged, likely impacted by broader concerns about rate-sensitive sectors and continued negative sentiment around the stock.

Treasury yields also fell following the inflation report, with the two-year yield dropping 9 basis points to 4.28% while the U.S. dollar weakened. Despite these broader market moves, Atomera's ( ATOM ) sharp decline may suggest company-specific pressures are compounding its struggles amid macroeconomic uncertainty.

ATOM Price Action: Atomera ( ATOM ) shares were down 20.2% at $8.91 at the time of writing, according to Benzinga Pro.
