$IONS Why is it so quiet here? is it because majority of the shares owned by insiders/institutions?

@FilingTracker· StockTwits2d ago

$IONS Insider purchased $1.06 million worth of shares: https://filingtracker.ai/filing/874015/0000874015-26-000254

@trader_q· StockTwits2d ago

$IONS hell is wrong with this stock no chance of going up.

@kb60521· StockTwits3d ago

$IONS Will this recover to 60? I started doubting 55 now....

6/ $IONS — Sept 22, 2026 PDUFA for zilganersen in Alexander disease. Thesis: ultra-rare neuro catalyst with Priority Review + Breakthrough/Orphan/Rare Pediatric Disease designations; first-and-only treatment potential vs small-market launch execution.

@BioAlphaSignals· StockTwits4d ago

1/ Biotech FDA catalysts I’m watching over the next ~60 days. Not investment advice — just a sourced watchlist. PDUFA dates can move, and binary FDA events can gap hard both ways. Sources are company IR/news releases. $REPL $BMY $RARE $GILD $IONS

@trader_q· StockTwits4d ago

$IONS earnings was very good. This will come around today and end bright green. Gl all.

@kellymone2· StockTwits4d ago

$IONS your thoughts on earnings?

@StocktwitsEarnings· StockTwits4d ago

$IONS Q2 '26 Earnings Results & Recap • Reported GAAP EPS of -$0.69 down -188.46% YoY • Reported revenue of $268M down -40.71% YoY • Ionis Pharmaceuticals remains on track to achieve its 2026 financial guidance, including full-year product sales targets for TRYNGOLZA and DAWNZERA, while maintaining its goal of cashflow breakeven in 2028.

@SecoTrader· StockTwits4d ago

$IONS right now sentiment is very negative, so a positive call could make it go up significantly. On the other hand a bad one would probably bring us to 50$ again, as per last week. We will know soon 😅

@trader_q· StockTwits5d ago

$IONS this is going to pull a KNSA-like move tomorrow with earnings. Gl all.
