Could have been fake/temporary bid. The actual fact on Course of Sales is that it opened sale at 2.4 went to 2.3 then back up to 2.5. Only 400K shares were sold at 2.5, there are no others for offer at that amount.
In short, I just think it is day traders or bots playing around, some may even be people a little nervous or fed up and getting out.
If it closes at 2.5 or above I will be happy. If it was a bad news leak I would expect to be way lower by now and a higher volume.
No news and delayed news is the most fearful news IMO. Lack of news always leads the mind to imagine differing possibilities. "Fear is the mind killer" to plagiarize a quote
For good or bad, I've stuck with CNX through all the hoops, jumps and BS they've worked their way through. They'll remain in the bottom draw and at the end of this small chapter of "The Life and Times of CNX" the wife will either be cracking champagne to drink, or alternatively cracking the champagne over my head. Cheers.
