Questions about WMS
What people ask.
Why is WMS on Broken Stocks?
WMS qualifies for the Watch on decline depth. It is down -21.8% from its rolling 252-day high of $179.13, set on 2026-02-11 — 92d ago.
Is WMS a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. WMS is down -21.8% 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 WMS 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 WMS trading inside its 52-week range?
At $140.09, WMS sits 47.4% of the way from its 52-week low ($104.69) to its 52-week high ($179.31). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has WMS been declining?
The current 21.8% decline accrued over 92d, which annualizes to roughly -86.5% 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 WMS compare to its sector?
There are 119 other Industrials tickers on Broken Stocks: 61 Red, 22 Amber, 36 Watch, with 23 showing recovering structural signals. Median sector decline is -32.6% — WMS's decline is shallower than the sector median.
Does WMS'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 (2026-05-21) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
