Over the next 20 trading days, similar setups historically landed in a measured range of outcomes. Unlock with Premium to see the median return, the typical range, and how often they were positive. This is the historical range of outcomes — not a prediction of this stock’s price.

Ranges describe how this exact setup resolved in the past — derived from thousands of historical occurrences across QuoTrend’s coverage since 2006, survivorship-corrected to include companies that later delisted. The band is the typical spread (±1σ) of those outcomes, not a forecast; the central value is their average move. Fewer matching cases over longer horizons widen the band and lower its reliability. Backtested results are hypothetical, based on historical data, and do not represent actual trading. Past performance does not guarantee or predict future results. QuoTrend is an educational research tool, not investment advice. Markets involve risk, including loss of principal.

Company

Founded in 1989 and headquartered in Carlsbad, California, Ionis Pharmaceuticals, Inc. is a biopharmaceutical company specializing in the discovery and development of RNA-targeted therapies within the United States. Its commercial portfolio includes three key medications: SPINRAZA, prescribed for spinal muscular atrophy (SMA) in both children and adults; TEGSEDI, an injectable treatment targeting polyneuropathy associated with hereditary transthyretin-mediated amyloidosis in adult patients; and WAYLIVRA, which addresses familial chylomicronemia syndrome and familial partial lipodystrophy. Ionis also maintains a robust pipeline, with several drug candidates currently in Phase 3 clinical trials. These include Eplontersen, a monthly self-administered subcutaneous injection designed for all forms of TTR amyloidosis; Olezarsen, intended for individuals with severe hypertriglyceridemia (SHTG); Donidalorsen, for patients suffering from hereditary angioedema; ION363, aimed at amyotrophic lateral sclerosis (ALS); Pelacarsen, developed for those with established cardiovascular disease and elevated lipoprotein(a); and Tofersen, which works by inhibiting the production of superoxide dismutase 1. Beyond these late-stage assets, the company is actively researching treatments for metabolic, infectious, renal, and ophthalmic diseases, as well as various types of cancer. The firm engages in significant collaborations, notably a strategic partnership with Biogen Inc. Additionally, it holds licensing and collaboration agreements with AstraZeneca, Bayer AG, GlaxoSmithKline plc, Novartis AG, Roche, Janssen Biotech, Inc., and Flamingo Therapeutics, Inc.
