Fidelity Information Services is trading 15.9% down at $38.69 in after-hours trading, marking a sharp reversal of its recent multi-day rally.

  • The stock fell significantly from its regular-session close of $46.02 despite a lack of fresh company-specific headlines or earnings releases.
  • The price swing appears to be amplified by thin after-hours liquidity ahead of the company's scheduled August 4 earnings report.
