Atara Biotherapeutics, Inc (ATRA) trades at $8.20 per share. The stock presents a bearish profile across the board: technical indicators signal "Strong Sell" and our fundamental models agree with a "Strong Sell" rating. Notable factors include a concerning Altman Z-Score in the distress zone, a weak Piotroski F-Score of 1/9, exceptional Return on Equity (25.4%) and a bearish Death Cross on the long-term moving averages. The stock looks compelling on valuation, with multiples below sector averages across P/E, P/B, and EV/EBITDA.
