Why it's moving
The likely cause behind today's biggest moves.
Research only. Not investment advice.
How this works
Movers are the biggest premarket, regular-session or after-hours moves (U.S. stocks over $300M market cap) plus stocks trading at 3× normal volume, from the Catalysts scan.
The cause comes from headlines and SEC filings the app already stores (last 3 days): an announced deal first, then FDA / trial news, guidance, earnings, analyst rating changes, share offerings and sale reports. If none of those match, it falls back to a scheduled earnings date, a new 13D stake or insider buying. It's a keyword match, so read the headline.
No news found is flagged in red: a big move with no headline or filing is worth extra caution.
