Roughly $7 billion in value disappeared from GE's market cap today. People are certainly going to investigate this more and the stock will move in one direction or another depending on the validity of the report, but regardless of the ultimate outcome significant capital was moved around today which presented an opportunity to make a lot of money.

Of course - but it moved precisely because people with money decided the claims were credible.
The market moved too quickly for the parties acting to have had time to actually digest the merits of the report. The market moved because the people who released the report had credibility.
It's possible that that was part of it. But the market closed with GE's price barely recovering. Which means people who analyzed it more slowly agreed with the initial movement. Which means there is no evidence for the view that the initial movement was spurious or unvetted.
It can also move by algos that listens to news coverage and they dont do much dd.
