On July 30, STMicroelectronics NV rose 6.47% in regular trading, trading at $52.12/share, with turnover of $88.22 million. The stock rallied alongside a broad semiconductor sector surge driven by strong cloud computing earnings and renewed AI infrastructure demand optimism.

On the news front, Microsoft reported quarterly results showing its cloud business grew at its fastest pace in four years, sending its shares up approximately 10% in pre-market trading. Analysts noted that robust second-quarter results from hyperscale cloud providers and disclosed AI data center projects represent a clear positive for semiconductor demand. The rally lifted major chip stocks broadly, with Micron Technology up 11.87%, SK Hynix up 10.76%, Advanced Micro Devices up 11.16%, and Intel up 10.33%.

STMicroelectronics NV had previously reported strong Q2 results on July 23, with adjusted EPS of $0.31 beating the $0.27 consensus by 14.8% and revenue of $3.49 billion exceeding estimates. The company also raised its AI data center revenue target to over $1 billion for the current fiscal year, with Q4 revenue expected to surpass $4 billion.
