An incredible streak to say the least.  Ryan Detrick has the numbers:  

Since WWII, the S&P 500 has been higher 12 months after the midterm elections every single time.

That is 18 for 18 with an avg again of 14.2%.

Currently up about 2% since the midterms last year.

We sure would welcome a pullback before the summer.  In that regard, we continue to focus on the Small Caps which have been lagging the broader indexes of late.  A healthy retrenchment would set the market up for a nice Q4 rally.
