Are Global Stock Markets Dancing to the Same Tune?

The ideas are vague and analysis superficial. The table doesn't show anything definitive; it is qualitative at best. Look, US down 13%, Brazil up 4 % in USD terms. Is this decoupled, or dancing to the same tune?
There are statistical methods for calculating covariances and time lags. It is hard to tell a complex story with English verbage and tables.
