Sera Prognostics Moves Up 15% Just Ahead of Holiday
Sera Prognostics shares jumped 15% to $2.07 Friday, trading over 530,000 shares—21 times the previous day’s volume—despite no new company disclosures. The move outpaced peers and came as Sera reported $14,000 in Q1 revenue, a net loss of $8.4 million, and $86.8 million in cash. Executives said 2026 revenue may stay “modest and uneven” as reimbursement and awareness efforts continue.
