Questions about WLK
What people ask.
Why is WLK on Broken Stocks?
WLK qualifies for the Red List on decline depth. It is down -42.3% from its rolling 252-day high of $122.63, set on 2026-04-07 — 159d ago.
Is WLK a falling knife?
Not by the strict technical definition. WLK is down -42.3% from its 52-week high, but that high was set 159d 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 Red 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 $70.81, WLK sits 21.3% 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 42.3% decline accrued over 159d, which annualizes to roughly -97.1% 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 WLK compare to its sector?
There are 171 other Basic Materials tickers on Broken Stocks: 87 Red, 47 Amber, 37 Watch, with 14 showing recovering structural signals. Median sector decline is -36.9% — 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.
