HBM qualifies for the Red List on decline depth — down -32.7% from its rolling 252-day high. Past 30% with the high set inside the last four months — the recency clause that often precedes further breakdown. Depth plus recency: this is the pattern many investors call a falling knife.

Upstream TFC read: weak alignment, current phase daily. Last bar types — daily 2U (green), weekly 2D (red), monthly 2D (red).

Questions about HBM
What people ask.
Why is HBM on Broken Stocks?
HBM qualifies for the Red List on decline depth. It is down -32.7% from its rolling 252-day high of $32.15, set on 2026-06-02 — 38d ago.
Is HBM a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. HBM is down -32.7% from its 52-week high of $32.15, set 38d ago. That combination of depth (past the 30% Amber threshold) and recency (high set inside the last 120 days) is the textbook falling-knife pattern. Whether to try to catch it is a separate question — historically most attempts to bottom-pick continue lower before reversing. Broken Stocks flags the pattern; it does not recommend buying or selling.
Is HBM 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 HBM trading inside its 52-week range?
At $21.64, HBM sits 54.7% of the way from its 52-week low ($8.93) to its 52-week high ($32.15). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has HBM been declining?
The current 32.7% decline accrued over 38d, which annualizes to roughly -314.1% 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 HBM compare to its sector?
There are 75 other Basic Materials tickers on Broken Stocks: 44 Red, 19 Amber, 12 Watch, with 14 showing recovering structural signals. Median sector decline is -38.3% — HBM's decline is shallower than the sector median.
Does HBM'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 (2026-05-01) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
