Most linked financial news is auto-generated and auto-correlated. Lots of "why did.." when nobody knows, and frankly there often is no why. Perhaps that was the day a retirement fund shifted money, who knows.

While this price movement is very well correlated, perhaps causal even, but marketwatch (and all similar bottom feeders that are just trying to make ad revenue), it's a case of a broken clock being right. Those financial news sites which link recent news to stocks, eg Yahoo, benzings, - those recent news headlines are just the same as ad tech now. It is noise.
