Questions about RGNX

What people ask.

Why is RGNX on Broken Stocks?

RGNX qualifies for the Amber List on decline depth. It is down -31.7% from its rolling 252-day high of $16.19, set on 2026-01-22 — 210d ago.

Is RGNX a falling knife?

Not by the strict technical definition. RGNX is down -31.7% from its 52-week high, but that high was set 210d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. RGNX is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.

Is RGNX 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 RGNX trading inside its 52-week range?

At $11.06, RGNX sits 52.2% of the way from its 52-week low ($5.46) to its 52-week high ($16.19). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has RGNX been declining?

The current 31.7% decline accrued over 210d, which annualizes to roughly -55.1% 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 RGNX compare to its sector?

There are 143 other Healthcare tickers on Broken Stocks: 70 Red, 34 Amber, 39 Watch, with 50 showing recovering structural signals. Median sector decline is -36.1% — RGNX's decline is shallower than the sector median.

Does RGNX'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 (2026-05-14) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
