Gappers stocks

Screening Filters

1. relative_vol: min 1.5

• Purpose: Finds stocks trading with above-average activity.
• Rationale: Gapper stocks often attract attention because they are moving sharply on meaningful volume. A relative volume threshold of 1.5 helps focus on names with stronger participation and a better chance that the gap is being supported by real market interest rather than thin trading.

2. region: US

• Purpose: Limits the search to U.S.-listed stocks.
• Rationale: This narrows the universe to the U.S. market, which is likely what the user wants when asking for “gapper stocks” in a general stock screening context. It also keeps the results consistent and easier to analyze within one market.

3. gap_pattern: GapUp

• Purpose: Identifies stocks opening above the prior day’s close.
• Rationale: A “gapper” is typically a stock that opens significantly away from the previous close. Since the query is specifically for “gapper stocks,” the GapUp filter directly targets the most relevant type of gap move: stocks gapping higher at the open.

Why Results Match:

• The GapUp filter directly captures the core idea of “gapper stocks,” which are stocks that open with a noticeable price gap.
• The relative volume filter helps ensure those gap moves are backed by strong trading interest, making the results more relevant and actionable.
• The US region filter keeps the screen focused on U.S. equities, which makes the list more specific and practical for the user.
