Editor’s notes
Monday's gap list had a $1.17 billion AI-infrastructure contract at a penny stock, a Phase 3 readout in eye disease and a cash takeover. Of the 10 largest opening gaps, 7 closed below their opening price and 3 held at or above it. None gave back the whole gap.
Market context: Major US indexes fell on the day; the S&P 500 and Nasdaq both declined as oil prices rose (TheStreet session recap).
By the numbers: Under FennEdge's default filters (US common stock or ADR, full-day volume ≥ 1M), 12 stocks opened at least 20% above their prior close.
The list is ranked by opening gap, not market cap.
