It does often seem that any news report about TSLA "soaring" or "plummeting" turns out to really just be a small'ish osscilation. At this point I tend to take most of these with a grain of salt.
The media tends to overstate how much a single story moves a stock. Not limited to Tesla, and I would say 10% is actually one of the larger movements than is typically associated with a single story within a day.
