Things are getting shaky around the world, as these charts from Italy and Spain show. There is also a very clear head & shoulder topping pattern being put in on the SPY hourly (thanks to Rick Xiphos for pointing this out).
Lastly, notice the Shiller S&P 500 P/E ratio chart. Can you see what happened in the summers of 2010 & 2011? Don't forget about sell in May and go away theory.
