Over on CAPS, fully 196 of the 203 All-Star members who have rated ADP -- some 96.5% -- believe the stock will outperform the S&P 500 going forward. These bulls include TMFBuck and dudemonkey.

In late February, TMFBuck reminded Fools that ADP "is an excellent business that generates a substantial amount of float." My Foolish colleague concludes: "In the event inflation rears its ugly head and interest rates rise, they will earn even more."

In a pitch from April, dudemonkey offers first-hand insight into ADP's advantages:

I'm the technical owner of our ADP applications at my company. Their offerings are comparable to their competitors, their support is reasonable, and their systems are sound although inscrutable at times. However, ADP has a strong economic moat due to the difficulty encounter when attempting to switch away from their applications. … ADP is known as the industry leader in business systems and has no serious competition to that title. It has competitors, for sure, but none of them have the reputation that ADP has. ADP is also a dividend aristocrat.
