Historically, bid.is.taken.out early but.apparently.the.support above subteen is too strong so there’s no incentive to throw away shares to eager accumulators.
Also, historically, the bid is taken out by sellers after a predetermined buyer volume is achieved, for example, the sellers will wait for let’s say 1 million+ buy volume in hopes all the early new money is complete and then the same few sellers will wipe out the bid lowering price to make shareholders think the company is failing.
Seen this happen myself for over a year, I’m sure it happened for much longer.
