C4 Therapeutics Inc is trading 5.2% down at $3.62 today amid a lack of fresh, company-specific news or filings pointing to a clear catalyst for the move.

  • The drop follows recent volatility after an 8.1% gain on June 10 and subsequent modest declines.
  • Broader U.S. indices are trading roughly flat to slightly lower, suggesting that sentiment and recent momentum may be driving today’s weakness rather than a new fundamental development.
