Citi analyst Peter Christiansen believes yesterday's Chevron (CVX) complaint news, its timing, and "poor communication" from FleetCor "certainly hurts" the company's credibility. While Chevon's suit should have a negligible impact on financials, current sentiment on FleetCor shares will likely limit upside for some time, Christiansen tells investors in a research note. He cut his price target for the stock to $165 from $200 but keeps a Buy rating on name. The analyst views yesterday's 5% selloff as overdone. FleetCor closed yesterday down $6.74 to $131.26.
