AI冲击蓝巨人，IBM股价单日暴跌超13%

Core Viewpoint - IBM's stock has experienced a significant decline due to concerns over artificial intelligence capabilities, particularly following a blog post from Anthropic that highlights the potential of its Claude Code to automate parts of COBOL modernization [2][3]. Group 1: Stock Performance - IBM's stock fell by 13.2% after Anthropic's announcement, making it the worst performer in the S&P 500 index on that day [3]. - Since early February, IBM's stock has dropped a total of 26.8%, potentially marking its worst month since December 1992 [3]. - The stock also recorded its largest single-day drop since March 12, 2020 [3].
