Since March 2009 the SP500 is up 250%, so another 10% gain is just chump change, and chasing it may be a step too far!

The Kitchin cycle (purple loops) suggests trouble can be expected between May 2017 and June 2018, readtheticker.com suggests a minimum 20% correction is a sure thing during the next 18 months with the TRUMP'ster around. Why chase a 10% gain now? Best waiting for the expected market correction before increasing your exposure to real market risk. Makes sense no! 

NOTE: The price chart below with our RTTHurstDPO indicator shows price is conforming to the 900 bar Kitchin cycle.

Ok maybe you don't get cycles or other chart reading tools, and you need a fundamental reason for such a market correction. Easy, how about rising inflation on the USA $66T of debt. A 1% inflation increase is $660BN loss in purchasing power. Higher interest rates normally follow higher inflation. The US inflation chart below is the chart to watch, nothing else matters. The FED will finally have its inflation problem.
