Citi upgrades Dick's Sporting Goods (DKS) to a buy rating after the company completed its acquisition of Foot Locker. Ben Watson laces up his technical analysis shoes and dives into the chart. On the last 5 days, he points to a re-test of the recent $230 resistance level with $207 acting as an area of downside support. Widening out to a 1-year chart for the athletics retailer, Ben notes the "megaphone" pattern taking shape since July which he says could be "exhaustive" for bulls.
