$GLSI I really believe we are approaching a period of frequent updates in a buildup to Bio Europe. Whether that begins this week or 3 weeks from now is anybody's guess, but Snehal has made Bio Europe an important event with his 8/10 PR....so expect him to make the supporting case with PRs over the next 2.5 months.

$GLSI On 9/17 (give or take a few days), looking for a virtual cut and paste PR of this March 17 PR (with a few updates to patient years and number of screened patients / screening rate). Maybe they will choose to include additional details regarding enrollment, but most important is staying anywhere close to that 83% number from March. I’d be thrilled with 75%. https://investor.greenwichlifesciences.com/news-events/press-releases/detail/117/open-label-arm-of-flamingo-01

$GLSI does anyone have any info on last lockup period extension? How early they filed that one ? Also, thoughts on extension or no extension !! If we didn't hear extension, will it be safe to assume that deals are closing sooner than later.

$GLSI Thank you Chat for your perspective: For GLSI specifically Given today's 173,750 shares traded and ~12% decline, I wouldn't be trying to "fight" the shorts. I'd focus on whether the fundamental thesis has changed. If it hasn't, the most effective long-side behavior is surprisingly boring: Hold → don't panic → don't lend shares if you don't want them lent → let the company produce catalysts → let price discovery happen. And if GLSI eventually produces genuinely compelling FLAMINGO-01 evidence, short positioning can become a source of upside rather than downside.
