Citi analyst Ashwin Shirvaikar recommends using the 6% selloff yesterday in shares of CSC (CSC) as a buying opportunity. The analyst expects investor interest to pick up as the process to close the merger with HP Enterprise's (HPE) Enterprise Services business wraps up during fiscal Q4. Among the reasons investors citied for the selloff were technical factors, President Trump's federal hiring freeze, Shirvaikar tells investors in a research note. He views CSC's current valuation as attractive and keeps a Buy rating on the name with a $70 price target.
