What Outliers cards are
An outlier card fires when a name in the Closelooknet universe moves beyond the 5% magnitude threshold in a session, in either direction. Each card attributes the cause where one exists — a print, a guide, an analyst move, a sector read-through — and flags when none does.
The unattributed ones are often the more useful signal: a large move with no news is usually positioning showing itself. The card frames each move against the name’s index membership and the day’s broader tape.
FAQ · from the current data
Quick answers
What counts as an outlier on the Closelooknet tape?
A move beyond the 5% magnitude threshold in one session by a name in the coverage universe, up or down. Cards attribute the cause where one exists and explicitly flag moves with no identifiable news.
Why track moves with no news?
A large move without a catalyst is usually positioning revealing itself — forced selling, a squeeze, or a crowded trade being reduced. Those moves often say more about the market state than the attributed ones.
