Sera Prognostics Moves Up 15% Just Ahead of Holiday
Sera Prognostics Inc. ended Friday up 15% at $2.07. The Nasdaq diagnostics stock, which usually sees thin action, saw 531,892 shares change hands—21 times what traded Thursday. SERA opened at $1.69 and touched $2.23 before settling. Timing is a factor. Sera’s investor-news page listed the May 6 first-quarter update as its most recent, and the filings page also showed May 6 as the latest for both its 8-K and 10-Q. There was no new disclosure from the company to explain Friday’s move.
