Dyne Therapeutics stock drops 5% into 2026 — FDA filing timeline and next earnings date in focus

Dyne Therapeutics’ stock has been on a tear following its latest clinical breakthroughs. Shares jumped 10–11% intraday on October 7, 2025, after the company reported positive one-year results from a key trial, lifting the stock to about $14.02 by mid-daymarketbeat.commarketbeat.com. This rally builds on a strong upward trend in recent months – the stock traded below $8 in spring 2025, so it has nearly doubled since then. Trading volume actually dipped on the spike, indicating the price jolt came on limited activitymarketbeat.commarketbeat.com.
