IBM Slid 5% Without An Earnings Report - Oct. 21 May Change The Case

IBM's stock fell 5% on Thursday, ahead of its earnings report due on Monday. The company's shares have been volatile in recent months, but this decline comes as a surprise as analysts had expected a positive earnings report.

The drop could be attributed to investors taking profits after a recent rally, or it could be a sign of caution ahead of the earnings report. IBM's earnings will be closely watched as it is a bellwether for the tech sector.
