The structural read
What price action says about DUOL.
DUOL qualifies for the Red List on decline depth — down -79.3% from its rolling 252-day high. Past the 40% threshold, the deepest tier in the taxonomy.
Alongside that decline, our proprietary engine has flagged a confirmed bullish structural signal on one or more time frames — moderate or strong time-frame-continuity (TFC) alignment — so the ticker also carries a Recovering badge. The two readings coexist: the tier tells you how deep the damage is, the Recovering badge tells you whether momentum may be turning. Recovering is not a buy signal; it's a structural read.
Broken Stocks stops here — it flags the structure, it doesn't build the upside case. Working out whether DUOL's turn is investable is what our sister tool does: ConvictionEdge — triple-engine conviction research on names showing a recovery signal.
Upstream TFC read: moderate alignment, current phase daily. Last bar types — daily 2U (green), weekly 1 (green), monthly 2U (red).
Earnings on file: 2026-05-04. Tiering is unaffected by earnings dates — listings reflect price structure only.

Questions about DUOL
What people ask.
Why is DUOL on Broken Stocks?
DUOL qualifies for the Red List on decline depth. It is down -79.3% from its rolling 252-day high of $541.46, set on 2025-05-15 — 366d ago. It additionally carries a Recovering badge — see below.
What does the Recovering badge mean for DUOL?
Recovering means our proprietary engine has flagged a confirmed bullish structural signal on one or more time frames (moderate or strong time-frame continuity). It coexists with the decline tier — DUOL is still Red List because the rolling-252-day decline hasn't healed, but a bullish setup has formed inside that decline. The two readings answer different questions: the tier tells you how deep the damage is; the Recovering badge tells you whether momentum may be turning. It's not a buy recommendation.
Is DUOL a falling knife?
Not by the strict technical definition. DUOL is down -79.3% from its 52-week high, but that high was set 366d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. DUOL is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is DUOL a buy?
Broken Stocks does not issue buy or sell recommendations. The list is a rules-based technical warning system. It tracks structural decline depth and recency — not company quality, management, fundamentals, or news. Always do your own research and consult a licensed advisor.
Where is DUOL trading inside its 52-week range?
At $112.06, DUOL sits 5.3% of the way from its 52-week low ($87.89) to its 52-week high ($541.46). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has DUOL been declining?
The current 79.3% decline accrued over 366d, which annualizes to roughly -79.1% per year. Annualized pace is a sanity check — a 30% decline in three months is a different signal than a 30% decline over two years.
How does DUOL compare to its sector?
There are 190 other Technology tickers on Broken Stocks: 131 Red, 41 Amber, 18 Watch, with 52 showing recovering structural signals. Median sector decline is -44.3% — DUOL's decline is deeper than the sector median.
Does DUOL's earnings date affect its tier?
No. Tiering is decided purely by decline depth and recency of the rolling-high date. The earnings date on file (2026-05-04) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
