Bloomberg News/Landov The Continental tire distribution center in Sumter, S.C.Investors have been tapping the brakes on German tire maker Continental’s shares lately, leading a bunch of bulls to say the stock may be a smart buy. A mid-April profit warning tied to the strengthening euro has put pressure on the stock. Gains for the currency, which is up about 9% against the dollar over the past 12 months, tend to cut into overseas revenue generated by multinationals such as Continental AG CON, -0.04% . In that warning last month, the company’s management said “exchange rate and inventory valuation effects” would hit first-half earnings — as well as cut into profit margins. But strategists at Germany’s DZ Bank have remained upbeat, recently adding the stock to their “equity long ideas” list. “The negative share-price reaction after Continental’s outlook adjustment seems overdone to us,” the bank’s team wrote in a note. “The margin adjustment is triggered by two one-time effects and will have no negative impact for mid- to long-term margin development.”via
