Wells Fargo analyst William Warmington views the recent selloff in Acxiom's (ACXM) share price as an overreaction to Facebook's (FB) decision to end its partnerships with 3rd-party data brokers that creates an attractive entry point for long-term investors. The analyst remains bullish on Acxiom given the limited direct financial impact of Facebook's decision, and an attractive valuation that implies minimal value for the AS and MS divisions. Warmington reiterates an Outperform rating on Acxiom's shares, while lowering his price target on the stock to $33 from $36.
