Ionis is best avoided because major Phase 3 trials still hang over it, making it hard to size a meaningful position while controlling risk. Biotechs can drop 10-30% overnight on a negative read-through from another company's similar drug, with no chance to react, and a 1-2% position is mostly a waste of time. Biotech names are worth owning only once profitable, generating real cash and free of major Phase 3 risk. x.comÂ
