Personally I would begin to unwind any margin LONG positions around those highs.
Previous Monthly Report
S&P 500 Primary and Weekly cycles
Primary trend continues to remain stable, as it head up towards the 2014 highs.
I would being to off load any margin positions around those highs and move to the sidelines,
and wait for the next pullback in the Quarterly cycles, as illustrated in the next chart
DOW Primary cycles
The DOW is following text book Dilernia Principles, as it follows the Primary breakout in 2013 towards the 2014 highs, whilst the Quarterly dynamic support levels provide the precise re-entry points.
Once again I would look to offload Margin positions around those yearly highs..
