On July 17, Rambus fell 6.14% in regular trading, trading at $93.91/share, with turnover of $22.97 million. The decline was driven by continued fallout from the Korean antitrust raid and broad-based weakness across the semiconductor storage sector.

On the news front, the Seoul Central District Prosecutors Office Fair Trade Investigation Division previously raided the Korean offices of Rambus, Montage Technology, and Renesas Electronics on suspicion of violating the Fair Trade Act by colluding on memory interface chip pricing. The three companies collectively control over 93% of the global DDR5 memory interface chip market, with Rambus holding approximately 20.5% share. Compounding the pressure, Rambus disclosed in April that it received a US federal grand jury subpoena related to a criminal price-fixing investigation, establishing a dual US-Korea regulatory siege that has intensified market concerns.

Within the Semiconductors sector, stocks declined broadly: Micron Technology down 4.55%, NVIDIA down 4.12%, Advanced Micro Devices down 7.3%, Intel down 6.9%, and Broadcom down 4.07%.
