Show me stocks in a downtrend

Screening Filters

1. PriceBelowMA20 (Price below 20-day moving average)

   • Purpose: Identify stocks whose current price is below their short-term trend line.
   • Rationale:
     • A 20-day moving average is a common proxy for short-term momentum.
     • When price is below the 20-day MA, it suggests recent weakness and that sellers are currently in control.
     • For a stock to be considered in a current downtrend, you generally want it trading below this short-term average rather than bouncing above it.

2. PriceBelowMA200 (Price below 200-day moving average)

   • Purpose: Capture stocks that are weak on a long-term basis, not just experiencing a brief pullback.
   • Rationale:
     • The 200-day moving average is a classic indicator of the long-term trend.
     • If price is below the 200-day MA, the market is typically viewing the stock as being in a broader, established downtrend.
     • Requiring both PriceBelowMA20 and PriceBelowMA200 aligns with a textbook definition of a confirmed downtrend: weakness in both short and long time frames.

3. month_price_change_pct: max = -5%

   • Purpose: Ensure the stock has declined over the last month.
   • Rationale:
     • A maximum of -5% means we only include stocks that are flat or down at least up to 5% over the past month (i.e., no strong recent rallies).
     • This aligns with the notion of a sustained downtrend, rather than a stock that has just dipped below a moving average for a day or two.

4. quarter_price_change_pct: max = -10%

   • Purpose: Confirm weakness over a slightly longer, intermediate horizon (about three months).
   • Rationale:
     • By capping the 3‑month change at -10%, we filter for stocks that have not been strong over the quarter and are likely in a broader weakening phase.
     • Combining negative 1‑month and 3‑month performance supports the idea of a continuing downtrend, not a momentary pullback.

5. industry: Passenger Transportation Services

   • Purpose: Focus on Delta’s direct industry peers.
   • Rationale:
     • Delta Air Lines (DAL) is an airline, which falls under Passenger Transportation Services.
     • Screening this specific industry allows you to see whether downtrends are stock-specific or part of a broader industry-wide weakness (e.g., all airlines under pressure vs. just DAL).
     • This is useful context for judging whether DAL’s trend is idiosyncratic or macro/sector driven.

6. region: United States

   • Purpose: Limit results to companies operating and listed primarily in Delta’s home market.
   • Rationale:
     • DAL is a U.S. company; U.S. peers share similar macro factors (U.S. economy, fuel regulations, labor markets, etc.).
     • This makes trend comparisons more meaningful than mixing in airlines from very different regulatory and economic environments.

7. list_exchange: XNYS, XNAS, XASE (NYSE, Nasdaq, NYSE American)

   • Purpose: Restrict to major U.S. exchanges.
   • Rationale:
     • DAL trades on the NYSE (XNYS).
     • Limiting to these primary exchanges ensures you’re comparing DAL to similarly regulated, liquid U.S. passenger carriers, avoiding obscure or lightly traded listings that might distort the picture.

Why Results Match Your Question (“Is DAL in a downtrend?”)

• A classic technical definition of a downtrend is:

  • Price below key moving averages (short- and long-term), and
  • Recent returns negative over multiple time horizons (e.g., 1–3 months).

• The filters combine to:

  • Capture U.S. passenger transportation stocks (DAL’s peer group) that are below both the 20-day and 200-day moving averages and have negative 1‑month and 3‑month performance.
  • This defines a clear, sustained downtrend profile.

• By checking whether DAL itself meets these same conditions (price vs. 20- and 200-day MAs, and its 1- and 3‑month performance), you can determine if DAL is exhibiting the same “downtrend” characteristics as the screened set.

  • If DAL is also below both moving averages and has negative 1- and 3‑month returns, it is very likely in a downtrend by standard technical criteria.
  • Comparing DAL’s behavior to its screened peers helps you see whether the downtrend is stock-specific or part of a broader industry pattern.
