I need to make a correction.  I read the volume from a "Summary" page chart on Yahoo Finance instead of from the "Historical Data" page.  When I checked on the Historical Data page for daily volumes it shows no volumes in the 1 million and above level during 2020.  As someone else pointed out today, the volume shown today is an all time high and this time I checked Historical Data all the way back to 2010.  I don't see any volume as high as it was here on 1 Feb 2021.  Okiedo
