Any stock free fall

Screening Filters

1. Market Cap ≥ $500M (market_cap: {'min': '500000000'})

   • Purpose: Focus on mid-cap and larger companies.
   • Rationale:
     • True “free fall” moves in tiny micro-caps may be due to illiquidity, manipulation, or single trades, not broad selling pressure.
     • A $500M+ floor keeps you in more established, better-traded names where a steep decline is more meaningful and easier to analyze and trade (tighter spreads, more volume, better news coverage).

2. Relative Volume ≥ 1.5 (relative_vol: {'min': '1.5'})

   • Purpose: Capture stocks trading with unusually high volume versus their normal levels.
   • Rationale:
     • “Free fall” implies heavy selling pressure, not just a drifting decline.
     • Relative volume ≥ 1.5 means the current trading activity is at least 50% higher than usual, signaling that the sell-off is attracting real participation (forced selling, panic, major news, etc.).

3. RSI Category = Oversold (rsi_category: ['oversold'])

   • Purpose: Identify stocks that are technically very weak in the short term.
   • Rationale:
     • An oversold RSI (commonly RSI < 30) is a classic sign of a sharp, persistent downward move.
     • This fits the idea of “free fall” as a strong downside momentum move, not just a mild pullback.

4. New 52-Week Low (new_high_low: ['52w_Low'])

   • Purpose: Find stocks breaking to their lowest level in the past year.
   • Rationale:
     • Hitting a new 52-week low, especially with high volume, is often associated with capitulation, panic selling, or major negative re-pricing.
     • This is exactly the kind of behavior that matches “currently experiencing a free fall” rather than just dropping from recent highs but still within a normal range.

5. 1-Week Price Change ≤ -15% (week_price_change_pct: {'max': '-15'})

   • Purpose: Ensure the recent drop is steep and rapid.
   • Rationale:
     • A decline of 15% or more in a week for a $500M+ stock is a strong negative move.
     • By capping at -15% (or worse), this filter selects names that have sold off sharply in the very recent past, aligning closely with “currently in free fall” rather than a slow, gradual downtrend.

6. Region = United States (region: ['United States'])

   • Purpose: Restrict the universe to U.S.-domiciled stocks.
   • Rationale:
     • Directly answers your focus on the US stock market.
     • Excludes foreign listings and ADRs that may trade in the U.S. but are not primarily U.S. companies.

7. Exchange in NYSE, NASDAQ, AMEX (list_exchange: ['XNYS', 'XNAS', 'XASE'])

   • Purpose: Limit to major U.S. exchanges.
   • Rationale:
     • Ensures you’re looking at more liquid, regulated, and widely followed stocks (no OTC/pink sheets).
     • Major exchange listing plus a big recent drop with high volume is much more indicative of a genuine, noteworthy “free fall.”

Why Results Match Your Request

• The combination of oversold RSI, new 52-week low, and ≥15% weekly drop targets stocks that are not just weak, but undergoing a sharp, accelerated decline consistent with your “free fall” description.
• High relative volume confirms that the drop is driven by strong selling interest, not random thin trading.
• Market cap and major exchange filters remove illiquid micro-caps and obscure names, so the “free fall” is meaningful in the context of the broader U.S. market.
• U.S. region and U.S. exchanges align the results squarely with the U.S. stock market you asked about.
