Questions about BLD

What people ask.

Why is BLD on Broken Stocks?

BLD qualifies for the Amber List on decline depth. It is down -36.6% from its rolling 252-day high of $559.47, set on 2026-02-17 — 184d ago.

Is BLD a falling knife?

Not by the strict technical definition. BLD is down -36.6% from its 52-week high, but that high was set 184d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. BLD is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.

Is BLD 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 BLD trading inside its 52-week range?

At $354.53, BLD sits 10.5% of the way from its 52-week low ($330.51) to its 52-week high ($559.47). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has BLD been declining?

The current 36.6% decline accrued over 184d, which annualizes to roughly -72.6% 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 BLD 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% — BLD's decline is deeper than the sector median.

Does BLD'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.
