Key Highlights
- Google introduced TurboQuant, a compression technology capable of shrinking AI memory needs by up to six times
- Samsung’s stock price declined 4.8% while SK Hynix experienced a 6.23% decrease
- American memory sector stocks including Micron, SanDisk, and Western Digital saw losses ranging from 1.6% to 3.5%
- Market experts characterize the downturn as temporary profit-taking rather than fundamental weakness
- TurboQuant will receive formal presentation at April’s ICLR 2026 conference
Major South Korean semiconductor manufacturers Samsung and SK Hynix witnessed significant stock price declines Thursday following the revelation of Google’s innovative AI memory compression technology, TurboQuant.
Trading on the Korea Exchange saw Samsung shares retreat 4.8% while SK Hynix experienced a steeper 6.23% decline. The two companies ranked among the primary contributors to the KOSPI index’s substantial 3% intraday loss.
The electrical and electronics sector index experienced a 4.76% decline, settling at 3,592.22 points.
This downturn mirrored previous losses observed in American memory sector equities. Micron Technology shares decreased 3.40%, SanDisk declined 3.50%, and Western Digital retreated 1.63% during New York Stock Exchange trading.
Google’s research team presented TurboQuant earlier this week. The breakthrough algorithm enables AI systems to process up to six times greater capacity while maintaining identical memory resource consumption.
According to Google, the innovation also enhances vector search operations that drive leading search platforms.
Market participants expressed apprehension that diminished memory requirements might curtail demand for sophisticated memory components supplied by Samsung and SK Hynix to data center operators.
Both corporations have experienced substantial benefits from AI-related demand growth. This surge had been creating memory chip supply constraints throughout recent quarters while propelling impressive stock performance for both companies.
Market Experts Challenge Pessimistic Interpretation
Majority of financial institutions characterize the decline as temporary profit realization. Industry specialists contend the innovation may actually bolster memory demand across extended timeframes.
Surim Lee, equity research analyst at DS Investment & Securities, explained that memory-saving technologies historically drive demand expansion. Lee highlighted that TurboQuant’s development stemmed from AI infrastructure memory constraints reaching critical thresholds.
Lee emphasized that efficiency improvements generate cycles where reduced costs stimulate increased usage and capital reinvestment.
Han Ji-young of Kiwoom Securities observed that enhanced AI model efficiency and capability could counterintuitively drive broader AI adoption.
Han additionally suggested the pronounced stock decline likely reflected investor exhaustion following early-year memory pricing strength, with TurboQuant news providing justification for profit capture.
Historical Precedents Reinforce Extended Outlook
Throughout history, innovations improving resource efficiency have frequently accelerated industry expansion and elevated aggregate demand.
Heo Jae-hwan of Eugene Investment & Securities stated that server and semiconductor segments connected to AI, where supply constraints already exist, will likely demonstrate greater resilience compared to alternative sectors.
Google confirmed TurboQuant will receive official presentation at April’s ICLR 2026 conference.
Samsung and SK Hynix concluded trading at 1,801,000 won and 9,330,000 won respectively on the Korea Exchange on March 26.
