Deutsche Bank analyst Ashish Sabadra downgraded Alliance Data Systems (ADS) to Hold from Buy and lowered his price target for the shares to $158 from $162. The analyst sees "multiple potential headwinds" for the company, including the reserve build, winding down portfolio held for sale, and declining interest rates weighing on earnings growth in 2020. The analyst points out that his 2020 earnings estimates are 10% below consensus. Alliance Data could continue to trade at a discount to Synchrony Financial (SYF) given its use of non-GAAP earnings and limited disclosures about consumer credit scores and revenue share, Sabadra tells investors in a research note.
