When a stock gaps higher at the open, the next question is simple: does it keep going or fade? Instead of guessing, you can use Market Chameleon’s Pre-Market Report to see how gap-ups have actually behaved after the bell—both into 10:00 a.m. ET and by the close—and shape a plan that fits your style.

Gaps compress a lot of overnight information into a single opening print. Many names show initial selling pressure as early buyers take profits or supply meets the spike, while others rebuild momentum into the afternoon. By grounding your morning prep in real, recent statistics, you give yourself a clearer expectation set for follow-through vs. fade.
Rolling 20-day outcomes: Win rates and average returns from the open to 10:00 a.m. and to the close for gap-up (and gap-down) cohorts.
Filters for precision: Tighten your universe by gap size (e.g., >5%) and market cap (e.g., $50B ). Behavior can differ meaningfully across these segments.
Outlier awareness: The report makes it easy to spot extreme moves that can skew averages, so you can interpret results with proper context.
Early softness is common: On average, gap-ups often dip in the first half-hour as supply hits the tape.
Recovery into the close is not unusual: Many names rebuild later, producing small positive averages by day’s end.
Bigger gaps, bigger morning headwinds: When you filter to larger gap percentages, the early drawdown tends to be more pronounced—even if the close looks similar to the broad group.
Large-cap profiles can differ: Higher-cap names often show steadier post-open behavior than smaller, more volatile stocks—another reason to segment your list.
Scan gap-ups in the Pre-Market Report and review to-10:00 and to-Close stats.
Filter by gap size and market cap to match your risk appetite.
Prioritize tickers that align with your playbook (e.g., large caps with better early follow-through, or high-gap names you prefer to fade).
Add context: Check catalysts (earnings, guidance, news), pre-market VWAP, and liquidity.
Confirm on the tape: Watch the first 15–30 minutes—does price hold above the open, reclaim pre-market highs, or slip toward the prior close?
Layer tools as needed: Time & sales, imbalance data, and options indicators (open interest changes, IV shifts) can help you validate the idea before you act.
You’re not trying to predict every open—you’re building a repeatable process that highlights where probabilities and context look favorable for you. The Pre-Market Report replaces guesswork with fast, relevant stats, so you can focus on execution and risk management.
