IBM stock drops 25 percent after disappointing quarterly results

IBM's share price dropped 25 percent on Tuesday, its worst single-day fall ever. The decline happened after the company made an unusual early announcement that its quarterly results would be worse than expected. Normally, companies wait for their official earnings report before sharing this kind of news. Investors reacted badly because they are worried about IBM's future. The company has already lost ground in recent years as the technology market has changed. Its core infrastructure business now faces serious pressure from competitors. The early warning has made shareholders question whether IBM can keep up with these changes and stay competitive in its most important business areas.
