If you believe BIIB can sustain its current profitability and modest growth while MRNA's losses and revenue decline persist, then BIIB is the stronger relative value choice because it combines positive earnings with a much lower P/S multiple and better capital efficiency.
BIIB trades at 3.0x P/S and 22.8x P/E versus MRNA at 11.6x P/S and no positive earnings, yet the provided implied price of $781.99 suggests a very large rerating from the current $200.54. The gap is driven mainly by BIIB's profitability and much stronger revenue base, while MRNA's negative margins and losses make sales-based valuation appear much less supported.
