Maybe happy days aren't here again.

Lately much talk on how economy in the U.S anyway is looking good:job growth,low inflation(although many economists worry about deflation) and until recently a stock that goes up and up.But there are clouds in this silver lining,for example the head of IMF stated the U.S economy is good but rest of the world is bad,well remember back in 2007 and 2008 the U.S was doing good and Europe wasn't but we were told not worry for there is de-coupling wrong by end of 2008 the U.S economy was down the tubes.Also worry the price gold is going up,but copper is down(five year low) and Vix is going up yet volume in the market is low.Maybe happy days aren't here again.
