Following a widespread sell-off in global markets the previous day, most Asian technology stocks rebounded in volatile trading on Wednesday.

The share price of South Korea's leading chip giant, Samsung Electronics Co., Ltd., surged over 9%, while SK Hynix Inc. rose 2.7%. Both stocks had plummeted more than 12% in the prior trading session.

Samsung Electronics and SK Hynix are core heavyweight components of the Korea Composite Stock Price Index (Kospi), which itself gained over 3% on the day.

Other South Korean tech stocks showed mixed performance: Samsung SDI Co., Ltd. climbed more than 4%, and Seoul Semiconductor Co., Ltd. jumped 5%.

In the Japanese market, chip equipment maker Advantest Corp. fell 0.51%, SoftBank Group Corp. advanced 1.84%, and Tokyo Electron Ltd. closed down 3%.

Analyst Dan Ives from Wedbush Securities stated that recent on-the-ground checks of the pan-Asian supply chain and enterprise AI demand trends show the industry's fundamentals remain "without a crack." He views the recent sharp decline in Korean tech stocks more as a technical pullback following the Kospi's near-doubling gains this year, rather than a signal of deteriorating fundamentals.

This rebound came after a brutal trading day on Wall Street, where tech stocks extended a global sell-off that had originated in Asia the day before.

The Nasdaq Composite Index tumbled 2.2%, and the Philadelphia Semiconductor Index also declined, as investors sold off shares of chipmakers and AI-related companies. Memory chip firms Micron Technology, Inc. and SanDisk Corp. plunged 13%, while Intel Corporation, Advanced Micro Devices, Inc., and Qualcomm Incorporated all fell more than 5%.
