Frequently asked questions about SERA activity
Which institutional owners are buying SERA?

What does "buy" mean in SERA activity?
"Buy" means an investor increased their reported position in SERA compared to the prior reporting period. This reflects growing exposure to SERA PROGNOSTICS INC-A (SERA) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).
Is institutional interest in SERA increasing?

A higher number of additions typically signals increasing participation among large filers, but it should be read alongside position sizes and the full table.
