The structural read
What price action says about WLK.
WLK qualifies for the Amber List on decline depth — down -36.1% from its rolling 252-day high.
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 WLK'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 1 (green), weekly 2D (red), monthly 3 (green).

Questions about WLK
What people ask.
Why is WLK on Broken Stocks?
WLK qualifies for the Amber List on decline depth. It is down -36.1% from its rolling 252-day high of $123.49, set on 2026-04-07 — 135d ago. It additionally carries a Recovering badge — see below.
What does the Recovering badge mean for WLK?
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 — WLK is still Amber 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 WLK a falling knife?
Not by the strict technical definition. WLK is down -36.1% from its 52-week high, but that high was set 135d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. WLK is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.
Is WLK 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 WLK trading inside its 52-week range?
At $78.85, WLK sits 33.2% of the way from its 52-week low ($56.33) to its 52-week high ($124.23). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has WLK been declining?
The current 36.1% decline accrued over 135d, which annualizes to roughly -97.6% 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 WLK compare to its sector?
There are 58 other Basic Materials tickers on Broken Stocks: 24 Red, 16 Amber, 18 Watch, with 16 showing recovering structural signals. Median sector decline is -33.5% — WLK's decline is deeper than the sector median.
Does WLK'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 (2026-08-04) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
