Questions about HDSN

What people ask.

Why is HDSN on Broken Stocks?

HDSN qualifies for the Red List on decline depth. It is down -49.0% from its rolling 252-day high of $10.52, set on 2025-09-15 — 255d ago.

Is HDSN a falling knife?

Not by the strict technical definition. HDSN is down -49.0% from its 52-week high, but that high was set 255d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. HDSN is still on the Red List for decline depth, but the freshness component of a falling knife is missing.

Is HDSN 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 HDSN trading inside its 52-week range?

At $5.37, HDSN sits 12.4% of the way from its 52-week low ($4.64) to its 52-week high ($10.52). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has HDSN been declining?

The current 49.0% decline accrued over 255d, which annualizes to roughly -70.1% 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 HDSN compare to its sector?

There are 52 other Basic Materials tickers on Broken Stocks: 20 Red, 6 Amber, 26 Watch, with 34 showing recovering structural signals. Median sector decline is -29.9% — HDSN's decline is deeper than the sector median.

Does HDSN'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 (2026-05-06) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
