If you believe BIIB can sustain its modest growth advantage and convert lower leverage into faster earnings expansion, then hold or accumulate selectively; otherwise, the richer multiples versus PFE and the -20.4% implied downside argue for caution or rotation into PFE.
BIIB trades at a premium to PFE on P/E, P/S, EV/EBITDA, and EV/Revenue despite only slightly better growth and margins. The valuation model implies $161.65 versus the current $202.95, or -20.4% downside, which sits below the historical band and above the DCF range.
