Is the US the Outlier?

Over the last 5 years its clear the US stock market has outperformed many other countries. Whats driving this stock market expansion and is most of the world slowing down? We can see most commodities are trading at levels not seen since the financial panic of 2009.  It seems amazing to me that the US stock market continues to rise and interest continue to fall.  I believe this is due to the central banks around the world changing the investment landscape causing investors to chase otherwise irrational investments. The charts below speak for themselves, Interest Rates, Commodities, and Hot US Sectors over long term view.
