Pfizer only has immunity from killing and injuring people. They do not have immunity from fraud and they don't have a guarantee of government backing for mandatory, perpetual, and expanding jab authority. There are some major waves coming at them. One, the vaccines don't work. Two, confidence in them is collapsing as people are not showing up for boosters. Three, Pfizer and Moderna are scrambling to keep the ingredients and trial results buried longer than the government's JFK files. Four, it is well known they broke the trial protocol when they unblinded the placebo group in the study used to grant the EUA at 60 days. Five, honk honk.
I think Pfizer is going to get used up and tossed aside if and when the truth comes out. Even with the run up, it's a crap stock. They're up 12% in two years after the government hands them a global captive market. For what the rest of the market did in that time, Pfizer has been a dawg. I think Bwoods nailed it, this is Monsanto/Bayer all over again. Even if it isn't, I wouldn't hang around to find out when plenty of other low beta dividend payers can perform better without all the risk.
