Late June of 2005 was the last time that Pfizer was this high on a closing basis and intraday. The stock broke down from the low 30's at the start of Q4-04 in the wake of MRK's Vioxx fiasco. It saw $30 for the last time in early November of that year. On 12/16/04, it was still a $28.98 stock at the close but then the next day came news that Pfizer's own Cox-2 drugs, Celebrex and Bextra, had failed in Stage 4 tests. To this date, Pfizer still has never managed to close above the $28.98 seen over eight years ago.
It looked like the stock might surpass that close going into the last week of June 2005 when on June 23, it closed at $28.90. But then came the Viagra blindness scare which drove the stock price down. This is the highest that Pfizer has gotten since then.
