Ionis Pharmaceuticals, Inc. Common Stock
IONSNASDAQ • USD
Market: OPEN
IONS is currently priced at $54.32. The stock presents a bearish profile across the board: technical indicators signal "Sell" and our fundamental models agree with a "Sell" rating. This is driven by a concerning Altman Z-Score in the distress zone, a weak Piotroski F-Score of 2/9, negative Return on Equity, a bearish Death Cross on the long-term moving averages and bearish long-term moving average alignment. On the valuation front, IONS trades at elevated multiples relative to its peers, earning a "Richly Valued" assessment.
