This is called Realsatire in German. "Not the Onion".

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 was an odd way of saying the average post-IPO buyer was breaking even and then they went and updated the prices at EoD yesterday without really changing the title and it become a bit silly. Then they didn't update it again this morning but it was not at all the case, by lunch very much actually the case, and currently back to where it was at close yesterday so the article is as confusing as it was last night.

Not really the type of article that was worth updating or sharing any time after it was originally written.

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.)

Seems to be a five day rolling window?
