Questions about QMCO

What people ask.

Why is QMCO on Broken Stocks?

QMCO qualifies for the Red List on decline depth. It is down -45.8% from its rolling 252-day high of $18.48, set on 2026-06-04 — 36d ago.

Is QMCO a falling knife?

By the most common technical definition — a steep, recent breakdown from a fresh high — yes. QMCO is down -45.8% from its 52-week high of $18.48, set 36d 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 QMCO 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 QMCO trading inside its 52-week range?

At $10.02, QMCO sits 40.8% of the way from its 52-week low ($4.19) to its 52-week high ($18.48). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has QMCO been declining?

The current 45.8% decline accrued over 36d, which annualizes to roughly -464.4% 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 QMCO compare to its sector?

There are 196 other Technology tickers on Broken Stocks: 119 Red, 46 Amber, 31 Watch, with 71 showing recovering structural signals. Median sector decline is -39.4% — QMCO's decline is deeper than the sector median.

Does QMCO'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 (2026-06-25) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
