Questions about NBTX

What people ask.

Why is NBTX on Broken Stocks?

NBTX qualifies for the Red List on decline depth. It is down -33.2% from its rolling 252-day high of $57.14, set on 2026-05-14 — 91d ago.

Is NBTX a falling knife?

By the most common technical definition — a steep, recent breakdown from a fresh high — yes. NBTX is down -33.2% from its 52-week high of $57.14, set 91d 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 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 $38.17, NBTX sits 62.2% 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 33.2% decline accrued over 91d, which annualizes to roughly -133.2% 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 NBTX compare to its sector?

There are 140 other Healthcare tickers on Broken Stocks: 67 Red, 34 Amber, 39 Watch, with 48 showing recovering structural signals. Median sector decline is -36.1% — NBTX's decline is shallower than the sector median.
