It mostly means the news is on autopilot and refuses to do real analysis and everythings just a horse race of feelings rather than real critical anlysis.
It’s a very common metric in finance (pronounced vee-wop), usually measured over a single day (though as in this case, it can be measured over multiple days). It represents the closest true answer to the question “what was such and such stock trading at on this day or across these days.” (Averaging closing prices is less representative, though fine for back-of-the-envelope work.)
