On July 30, Acm Research Inc. rose 11.09% in regular trading, trading at $75.775/share, with turnover of $20.24 million.

The rally was driven by a broad rebound across the semiconductor equipment sector. The Philadelphia Semiconductor Index surged 5.79% as the U.S. market rallied on strong tech earnings, notably Microsoft's fourth fiscal quarter results showing Azure cloud business far exceeding expectations, signaling AI monetization entering an acceleration phase. Arm Holdings jumped over 17%, further boosting sentiment across chip-related names.

Within the Semiconductor Equipment sector, Lam Research led with a 21.27% gain, followed by Applied Materials up 14.85%, Teradyne up 12.37%, KLA-Tencor up 8.56%, and ASML up 7.20%. The sector-wide strength follows a period of notable correction since late July, with industry analysts noting that prior pullbacks had largely released valuation risk. SEMI forecasts global semiconductor equipment sales reaching $165.9 billion this year, up 23.2% year-over-year, underpinned by AI-driven capacity expansion and advanced process investments.
