Does the end of QT mean a bull market is coming right away?

After the end of QT in late July 2019, there were a few days of good market performance

Then the market began to experience frustrating ups and downs

Until just before QE started, there was a 312 black swan event that caused a crash

Some say it might be caused by the pandemic

Actually, I looked into it, and the pandemic has been on the rise since it started

312 was a sudden event, and if we don't consider it

After the last end of QT, there were also several pullbacks that led to the exit of short sellers.
