About Atara Biotherapeutics, Inc. (ATRA)

Atara Biotherapeutics Inc operates in the United States healthcare sector. It focuses on developing transformative therapies for patients with serious diseases, including solid tumors, hematologic cancers, and autoimmune diseases. It operates and manages business as one operating and reportable segment which is the business of developing therapeutics. The company's product candidates comprise Tab-cel, ATA3431, and ATA3219.

ATRA trades on NASDAQ and is tracked by the PennyStock.Ninja real-time scanner. The scanner monitors ATRA for premarket gaps, unusual relative volume (RVOL), VWAP reclaims and rejections, and vibe signals such as the Surfer breakout, Ninja stealth accumulation, and Fade caution patterns. Biotech and healthcare names like this one are highly catalyst-driven — FDA decisions, clinical trial results, and PDUFA dates can move the stock 50-200% in a single session, so position sizing and stop discipline matter more here than in any other sector.

What to watch on ATRA

RVOLWatch for ATRA trading at 3× or more its average volume — this is the first tell that something is moving. Confirm with price direction before assuming it is bullish; high RVOL on a red candle below VWAP is distribution, not accumulation.
VWAPIf ATRA is holding above VWAP on rising volume, bulls are in control intraday. A clean VWAP reclaim after a morning dip is one of the highest-probability long setups for penny stocks.
Premarket gapA premarket gap on ATRA with an identifiable catalyst (earnings, FDA, contract, partnership) is the most reliable setup. Gaps without news fade more often than they hold.
Float & short interestLow-float names with elevated short interest can squeeze violently. Always check the float and short interest on ATRA before sizing into a momentum trade.
HaltsATRA can be halted (T1 news pending, T12 information request, or LULD volatility). Wait for the resume print and the first 1-minute candle before re-entering.

Is ATRA a good penny stock to buy?

What is ATRA's RVOL and why does it matter?

What is ATRA's float and short interest?

ATRA float is shown in the "Short Interest & Float" panel above. Low-float names (under 75M shares) with elevated short interest can squeeze violently — always check both before sizing into a momentum trade. Live short interest, days-to-cover, and the Ninja Squeeze Score are members-only.
