Questions about ARQQ

What people ask.

Why is ARQQ on Broken Stocks?

ARQQ qualifies for the Red List on decline depth. It is down -77.6% from its rolling 252-day high of $62.00, set on 2025-10-08 — 218d ago.

Is ARQQ a falling knife?

Not by the strict technical definition. ARQQ is down -77.6% from its 52-week high, but that high was set 218d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ARQQ is still on the Red List for decline depth, but the freshness component of a falling knife is missing.

Is ARQQ 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 ARQQ trading inside its 52-week range?

At $13.87, ARQQ sits 4.7% of the way from its 52-week low ($11.52) to its 52-week high ($62.00). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has ARQQ been declining?

The current 77.6% decline accrued over 218d, which annualizes to roughly -129.9% 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 ARQQ compare to its sector?

There are 172 other Technology tickers on Broken Stocks: 118 Red, 36 Amber, 18 Watch, with 46 showing recovering structural signals. Median sector decline is -44.1% — ARQQ's decline is deeper than the sector median.

Does ARQQ'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 (2025-12-09) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
