Seaport Global analyst Michael Shlisky upgraded Douglas Dynamics to Buy from Neutral following Seaport Global's Industrials Exchange conference call with management. The analyst believes the core business and Hnderson are tracking in lie with expectations, and reduced 2016 volumes may allow the company to pursue incremental Douglas Dynamics Management System, or DDMS changes that were not available before. Shlisky continued, shares have pulled back over the last few weeks to more moderate valuation levels with most drivers of the business unchanged.
