Screening Filters
week_price_change_pct: { min: 500 }
- Purpose: Find stocks whose price increased by at least +500% over the last week.
- Rationale:
- Your question: “What stocks were up over 500% last week?”
- “Up over 500% last week” is exactly captured by this filter: it keeps only stocks whose weekly percentage gain ≥ 500% (i.e., ≥ 6× their price from a week ago).
- This is an extremely high threshold; even highly volatile small caps and biotech names rarely show a genuine +500% move in a single week on major exchanges.
list_exchange: ['XNYS', 'XNAS', 'XASE']
- Purpose: Limit results to stocks listed on major U.S. exchanges:
- XNYS = NYSE
- XNAS = NASDAQ
- XASE = NYSE American (formerly AMEX)
- Rationale:
- These exchanges cover most well-tracked, regulated U.S. listed stocks.
- Excluding OTC/pink-sheet or foreign exchanges reduces noise from illiquid or poorly documented names where extreme percentage moves might just be bad prints or data errors.
- This aligns with typical investor focus and data reliability.
Do the Filters Match Your Request?
- Yes, the filters directly match what you asked:
- You asked for: “stocks… up over 500% last week?”
- We screened for:
week_price_change_pct ≥ 500% over the last week on major U.S. exchanges.
- We are using indicators that we fully support (weekly price change and exchange listing), so there’s no substitution here—your request is being followed literally.
Why No Results Were Returned
- Moves of +500% in a single week on NYSE/NASDAQ/AMEX are extraordinarily rare.
- Genuine 5× moves in one week typically occur, if at all, in:
- Very low-priced microcaps,
- Highly illiquid or distressed names,
- Sometimes in OTC or non-U.S. markets (which we excluded).
- On major U.S. exchanges, such a move is usually associated with:
- Trading halts, restructurings, reverse splits, or data anomalies,
- Or extremely unusual events (and even then, still rare).
- Given that we’re searching the recent past (last week only) and restricting to these exchanges, it’s not surprising that no stock met the ≥500% weekly gain filter.
Would You Like to Adjust the Filters?
To actually see names, we’ll almost certainly need to lower the threshold. For example, we could try:
week_price_change_pct ≥ 100% (doubled in a week), or
week_price_change_pct ≥ 50% (up at least 50% in a week).
We can also:
- Keep the focus on major U.S. exchanges, or
- Expand to include more venues (with the caveat of more noise and lower-quality names).
What minimum weekly gain would you like to use instead—100%, 50%, or another level?
