You know, it's their favorite thing. They like to do that. Sometimes it means nothing. Sometimes it means everything. 

Our economy is overly abstracted. Let's be honest. The value of the stock market does not correspond with the health of the economy in as direct a relationship as we are taught to believe. Healthy industries can be wiped out by really, really stupid nonsense that sparks a panic. And then we all suffer.

Very nice system we got here. Very cool.

At least our stock markets are tagged to actual industries and companies, though. Not so much  the case here.
