Evidence & confidence

Binary catalyst with limited historical data; market may price in expectations but react sharply to outcome.

$MNOVNeutralMedium confidence
Context

MN‑001 Phase II data expected in September 2026 and COMBAT‑ALS readout by year‑end 2026.

Expected impact

Significant upside if Phase II meets endpoints; sharp decline if results are negative.

Evidence & confidence

Recent 86% weekly price gain suggests market is pricing in upside, but binary risk remains high.

$INONeutralMedium confidence
Context

FDA PDUFA decision for INO‑3107 scheduled for October 30, 2026.

Expected impact

Positive decision may trigger a multi‑digit rally; denial likely to cause steep sell‑off.

Context

LUCIA Phase III data expected in Q4 2026.

Expected impact

Positive data may halt the 71% three‑month decline; negative data could deepen losses.
