Questions about ROCK
What people ask.
Why is ROCK on Broken Stocks?
ROCK qualifies for the Amber List on decline depth. It is down -38.2% from its rolling 252-day high of $75.08, set on 2025-10-22 — 302d ago.
Is ROCK a falling knife?
Not by the strict technical definition. ROCK is down -38.2% from its 52-week high, but that high was set 302d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ROCK is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.
Is ROCK 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 ROCK trading inside its 52-week range?
At $46.39, ROCK sits 30.9% of the way from its 52-week low ($33.56) to its 52-week high ($75.08). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ROCK been declining?
The current 38.2% decline accrued over 302d, which annualizes to roughly -46.2% 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 ROCK compare to its sector?
There are 151 other Industrials tickers on Broken Stocks: 67 Red, 41 Amber, 43 Watch, with 29 showing recovering structural signals. Median sector decline is -30.8% — ROCK's decline is deeper than the sector median.
Does ROCK'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 (2026-08-05) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
