Pfizer (PFE) trades at about 95% of its 52-week high. The business that has to justify that price, the medicines it has launched and acquired, is still only about a fifth of the company. The stock returned roughly 24% over the past year against about 17% for the S&P 500, so investors have so far given the handoff the benefit of the doubt. It is a large bet on a small slice.
