Chris Versace says the government shutdown is putting a "crimp" on the volume of data investors and traders typically rely on for economic performance. He says the ISM reports are a "treasure trove" and believes investors need to be more fluid when it comes to triangulating data sources. Looking ahead, he thinks the upcoming earnings season will be very important and provide a "litmus test" for the current rally. Chris adds commentary on the latest retail shopping events competing between Walmart (WMT), Target (TGT) and Amazon (AMZN).
