Why CMPS stock is up today

Compass Pathways ADR (CMPS) surged 11.25% to $15.62 in early trading on Tuesday, driven by positive 52-week data from its Phase 3 COMP005 trial for treatment-resistant depression. The stock opened with a 2.2% gap up and reached a session high of $15.66 before settling near $15.60. The rally reflects growing confidence in the company’s regulatory pathway and commercial prospects for its psilocybin-based therapy COMP360.

What Happened

Compass Pathways reported topline results from Part C of its Phase 3 COMP005 trial, showing that patients who received an additional 25 mg dose of COMP360 experienced an average 13-point improvement in depression scores after 52 weeks. The open-label study also reported 40%-45% response rates and approximately 30% remission rates. These findings suggest that a second dose may extend the therapeutic benefit of COMP360 out to one year, reinforcing the durability of the treatment.

Jefferies reiterates its positive stance on the stock, citing confidence in the company’s path to TRD approval. Compass also announced a rolling FDA application is underway, with the full NDA expected in Q4 2026 and a potential U.S. launch in H1 2027 if approved. In addition, the company is preparing a U.S. healthcare provider education campaign and will present new data at the Psych Congress in September 2026.

What The Data Shows

The stock opened at $14.35 and traded in a wide range, reaching a high of $15.66. Volume so far stands at 3.0 million shares, or 0.8 times the 3-month daily average. The stock has printed two fresh 52-week lows and 21 52-week highs on September 9, 2026. CMPS is currently trading near its 52-week high of $15.40, suggesting strong near-term momentum. The stock’s beta of 2.55 indicates it is more volatile than the broader market.

What To Watch

The next key milestone for Compass Pathways is the completion of its NDA submission in Q4 2026, followed by the potential U.S. launch of COMP360 in H1 2027. Investors will also be watching for further coverage from analysts and the broader market reaction to the Phase 3 data as the stock continues to trade near its 52-week high.
