Questions about BLDR
What people ask.
Why is BLDR on Broken Stocks?
BLDR qualifies for the Red List on decline depth. It is down -53.4% from its rolling 252-day high of $151.03, set on 2025-09-05 — 349d ago.
Is BLDR a falling knife?
Not by the strict technical definition. BLDR is down -53.4% from its 52-week high, but that high was set 349d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. BLDR is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is BLDR 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 BLDR trading inside its 52-week range?
At $70.32, BLDR sits 6.1% of the way from its 52-week low ($65.10) to its 52-week high ($151.03). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has BLDR been declining?
The current 53.4% decline accrued over 349d, which annualizes to roughly -55.8% 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 BLDR compare to its sector?
There are 151 other Industrials tickers on Broken Stocks: 66 Red, 42 Amber, 43 Watch, with 29 showing recovering structural signals. Median sector decline is -30.8% — BLDR's decline is deeper than the sector median.
Does BLDR'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 (2026-07-30) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
