Just checked the price history on Yahoo:

Apparently in October, on the day after I was watching it closely, PFE hit $41.45 as the absolute low, but I don't even remember that happening! Perhaps I slept through it, or missed it as it happened and then blocked out the pain of the memory, or have otherwise forgotten the exact details of mid-October 2022.

Anyway for the record:

$41.45 was the absolute low in October it seems.

The absolute low on Friday last week was $41.51.

In late 2021, $40.94 and $41.04 were the absolute lows, a couple of days apart, shortly prior to Paxlovid being announced as successful then approved for emergency use.

Mid-early 2021 (early days of vaccination, long before paxlovid) was much a lower price, with a low point of $33.36
