$ALDX it’s interesting that Todd bought more shares, since he’s prohibited from buying shares if he has bad news, but with that being said, he’s at other missteps in his past

$ALDX Back in the $4.85–5.00 range, which has become an important short-term support area after the recent volatility. If buyers defend this zone, the stock has a chance to rebuild momentum. Lose it, and another leg lower becomes more likely. This is one of those levels where price usually decides quickly. Anyone watching for a bounce here or waiting for a confirmed reclaim?

$ALDX "The company's leadership recently indicated they are in the final stages of the process. In early June 2026, CEO Todd Brady stated that Aldeyra was "days away" from receiving preliminary FDA comments ahead of their upcoming Type A meeting regarding the Complete Response Letter (CRL) for reproxalap" "Official Meeting Minutes: Aldeyra expects to receive the official meeting minutes 30 days after the Type A meeting takes place' "Alternative Paths: If the FDA maintains its rejection stance during this meeting, management has noted they will consider moving to a Formal Dispute Resolution Request (appeal) process through the FDA’s Office of New Drugs"!
