Stifel analyst David Grossman says that while he looks forward to Pershing Square's presentation Thursday, his analysis suggests ADP's margins are "reasonable" based on its business model and current mix of business. Management and the board has worked hard to balance growth and profitability against stability, Grossman tell investors in a research note partially titled, "They May Have a Case, Though Not Immediately Obvious to Us." The analyst believes any effort to improve margins will need to be viewed in the context of that trade-off. He also questions how much near-term opportunity has already been priced in the shares post Pershing's involvement. Grossman has a Hold rating on ADP with a $108 price target.
