3 years more than 40 porcent decline

Screening Filters

1. year_price_change_pct: { max: "-40" }

   • Purpose: Select stocks whose share price is down 40% or more over the last 12 months.
   • Rationale:
     • Your request: “declined more than 40% in the past 3 years.”
     • The screener only provides a 1‑year price change (%), not a 3‑year performance field.
     • Using max: "-40" ensures we only capture stocks that have dropped at least 40% over the last year, which is a strong indication of significant underperformance and is directionally consistent with what you’re looking for (deeply sold‑off names).
     • It’s not a perfect substitute for a full 3‑year drawdown, but it still surfaces severely beaten‑down tech stocks, which is likely close to your intent.

2. sector: ["Technology", "Software & IT Services", "Technology Equipment"]

   • Purpose: Restrict the search to technology‑related companies.
   • Rationale:
     • You explicitly asked for “tech stocks”.
     • These sector buckets collectively cover the major tech areas:
       • General Technology
       • Software & IT Services
       • Technology Hardware/Equipment
     • This ensures we’re not pulling in non‑tech sectors (e.g., Financials, Industrials) even if they have similar price declines.

3. list_exchange: ["XNYS", "XNAS", "XASE"]

   • Purpose: Limit results to stocks listed on the major U.S. exchanges:
     • XNYS = NYSE
     • XNAS = NASDAQ
     • XASE = NYSE American (formerly AMEX)
   • Rationale:
     • Keeps the universe to more liquid, established U.S. listings, which are generally more relevant and easier to trade and research.
     • Avoids over‑the‑counter and very illiquid names, which may be riskier or have unreliable pricing.

Why Results Match (and Where They Differ from Your Exact Request)

• Match with your intent:

  • We are:
    • Focusing on tech stocks only (via the sector filter).
    • Ensuring they have suffered large price declines (≥40%) (via year_price_change_pct ≤ -40%).
  • This aligns well with your goal of finding severely beaten‑down tech stocks.

• Limitation vs. your exact wording (“past 3 years”):

  • The screener does not provide a 3‑year price change field, so we cannot directly filter on 3‑year performance.
  • Instead, we use the 1‑year price change as a proxy:
    • It reliably finds tech stocks that are currently in deep drawdowns.
    • However, it does not guarantee that the stock is down >40% over the full 3‑year period (e.g., a stock could have risen strongly 2 years ago and crashed in the last year).

So while we cannot exactly screen “3‑year decline >40%” due to data limitations, these filters effectively surface U.S. tech companies that have been crushed (down at least 40%) over the last year, which is a practical and closely related way to address your request.
