Why did MSB rise 9.4% on 21 Oct 2025?
Mesoblast
Mesoblast's founder publicly refuted short sellers, likely triggering a short squeeze.
The only news article close to the event date is from AFR, titled 'How Mesoblast's founder proved the shorters wrong,' published two days before the price move. This directly relates to a battle with short sellers, and combined with a 3.8x normal trading range suggestive of a sharp positional adjustment, a short squeeze is the most plausible driver. However, there is no explicit mention of a squeeze, so confidence is medium.
