International Business Machines Corp. shares had their worst day in more than 25 years on Monday, after AI startup Anthropic PBC said its Claude Code tool can help modernize Cobol, a dated programming language that’s run on IBM computers.
The stock plunged 13% in its biggest single-day percentage loss since October 2000. With the decline, IBM shares have fallen 27% in February, on track for its biggest one-month slide since at least 1968, according to data compiled by Bloomberg.
