The signal set leans bearish because the most active credible voice is using strength above $100 to sell rather than add. The late-week shift was intensifying trim language from @Biotech2k1, moving from eventual exit to active sale/redeployment plans. Trade structure reads as sell into FOMO after positive regulatory/data catalysts, not a fresh accumulation setup.

BULL CAMP2 claims

Bulls point to positive pivotal PROGRESS data, strong lesion-volume reduction, and Priority Review as evidence the regulatory path still has upside value.

BEAR / SKEPTIC3 claims

The bear camp is concentrated in @Biotech2k1, who sees MIRM above $100 as bubbly, wants to sell into FOMO, and redeploy into cheaper stronger names.

Desk readconvergence assessment
The view is not converged: positive regulatory and clinical signals exist, but the highest-volume credible author is focused on exit timing and valuation risk. Bull evidence is event-driven and credible but thinly represented, while the bear or de-risking case is concentrated in one medium-high credibility voice. A cleaner view would require either broader credible accumulation after the data or confirmation that the Priority Review path changes expected value enough to offset bubble concerns.
