This is my take on this, .40 cents attracted a lot ofsellers, the market maker saw this and got overwhelmed for not being able to support it, saw he took out the .4 to allow the press release and the following article to be absorbed by the market.
"Stronger Than Ever, Boron and This Upstart Explorer Should Be on Every Investor’s Radar"
.40 is likely to happen eventually, organically...
Cheers!
