Questions about WLK
What people ask.
Why is WLK on Broken Stocks?
WLK qualifies for the Red List on decline depth. It is down -29.0% from its rolling 252-day high of $123.49, set on 2026-04-07 — 51d ago.
Is WLK a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. WLK is down -29.0% from its 52-week high, which qualifies for the Watch tier but is shallower than the falling-knife pattern. It's an early-stage decline rather than a sharp breakdown.
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 $87.67, WLK sits 46.2% 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 29.0% decline accrued over 51d, which annualizes to roughly -207.5% 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 52 other Basic Materials tickers on Broken Stocks: 20 Red, 6 Amber, 26 Watch, with 34 showing recovering structural signals. Median sector decline is -30.0% — WLK's decline is shallower 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 (2026-05-05) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
