Wednesday's weak economic data continues a recent trend and the “negative seasonality factor” will likely keep the markets choppy for the “next few months,” said Ryan Detrick, senior technical strategist at Schaeffer’s Investment Research.

Schaeffer claims that the stock market is in an “excellent technical condition” and targets an additional market gain of 15 to 20 percent through year-end, sending the S&P to an all-time high and the Dow to near 15,000.
