Questions about NBTX

What people ask.

Why is NBTX on Broken Stocks?

NBTX qualifies for the Watch on decline depth. It is down -23.6% from its rolling 252-day high of $57.14, set on 2026-05-14 — 98d ago.

Is NBTX a falling knife?

No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. NBTX is down -23.6% from its 52-week high, which qualifies for the Watch tier but is shallower than the falling-knife pattern. It's an early-stage decline rather than a sharp breakdown.

Is NBTX 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 NBTX trading inside its 52-week range?

At $43.68, NBTX sits 73.2% of the way from its 52-week low ($6.97) to its 52-week high ($57.14). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has NBTX been declining?

The current 23.6% decline accrued over 98d, which annualizes to roughly -87.9% 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.

There are 143 other Healthcare tickers on Broken Stocks: 70 Red, 35 Amber, 38 Watch, with 50 showing recovering structural signals. Median sector decline is -36.1% — NBTX's decline is shallower than the sector median.
