That’s normal with this stock seen similar sells and bid come backs over the past 2 years with this. Not sure why but my guess is usually happens with the once in a blue lucky market sells that happen Seems to not faze or worry any investors, that’s why you don’t see anyone get worried and follow with additional sells you just see more bids come in like myself wishing they caught those lucky small sells.
Today was worst day on market overall in long time, Dow down 666 points. The lack of lower Ask indicates a lack of supply of sellers in the stock. Its been in a new ballpark last 8 days or so, and one of a tiny number of stocks that is up in that period.
