If you are short and wondering why this is happening
It is because the 5 day high was taken out. Pretty much the shorts that are stuck with in that 5 day highest high and 5 day highest low who did not cover are being forced to cover over 27.64. Not complicated.
Monday will be a new 5 day high but, there is no reason to BUY it now. The buy was close to 27.34 if you wanted in on the squeeze.
