RSI < 40 big cap

Screening Filters

1. market_cap_category: ['mega', 'large']

   • Purpose: Capture “big cap” stocks.
   • Rationale:
     • In most screeners, “big caps” are represented by large-cap and mega-cap companies (typically multi‑billion to hundreds of billions in market value).
     • By restricting to mega and large, the screener focuses on the larger, more established, more liquid names that match your “big cap” requirement.

2. rsi_category: ['oversold', 'moderate']

   • Purpose: Approximate a “low-ish RSI” universe in lieu of a precise numeric cut like RSI < 40.
   • Rationale:
     • The system does not support exact numerical RSI cutoffs (e.g., “RSI < 40”) directly. Instead, it groups RSI into broad bands such as:
       • Oversold: very low RSI (typically <30–35 range in concept)
       • Moderate: mid-level RSI (around 40–60 conceptually)
       • Overbought: high RSI
     • Choosing ['oversold', 'moderate']:
       • Includes oversold names, which are the closest conceptual match to your “RSI < 40” request (very weak momentum/washed out names).
       • Also includes moderate RSI names, capturing stocks that are around the low‑to‑mid range and might be just above or around 40, so you don’t miss candidates that hover near that boundary.

Do the Filters Exactly Match “RSI < 40 big cap”?

• Big cap:

  • ✅ Matched well: market_cap_category: ['mega', 'large'] is a direct, appropriate translation of “big cap.”

• RSI < 40:

  • ❌ Not an exact match: The screener cannot filter on “RSI < 40” numerically. It can only use RSI categories.
  • Instead, it uses rsi_category: ['oversold', 'moderate'], which:
    • Covers oversold names, consistent with the “low RSI” idea.
    • Broadens to moderate RSI, so the pool includes stocks that are not overbought but may be slightly above 40 as well.

Why Results Still Address Your Question

• You explicitly want big caps → the mega and large filters enforce that.
• You want RSI on the lower side →
  • We can’t set a hard RSI < 40 numeric cut, but
  • Using oversold ensures inclusion of very low-RSI stocks.
  • Adding moderate avoids overly restricting the universe and keeps stocks that are near, or just above, your desired threshold, still avoiding overbought/high‑RSI names.

If you’d like, we can next narrow the interpretation (e.g., use only oversold to get closer to your “RSI < 40” intent, at the cost of fewer candidates).
