On CAPS, 94.5% of the 1,032 members who have rated ADP believe the stock will outperform the S&P 500 going forward. These bulls include All-Star TMFDeej, who is ranked in the top 1% of our community, and TMFMMTInvestor.

Earlier this month, TMFDeej tapped ADP as an attractive income opportunity: "A solid company that pays a solid dividend for you to wait until either the jobs picture begins to improve or interest rates begin to rise ... both of which will cause ADP's earnings to improve significantly."

ADP's massive scale, high customer switching costs, and cheapish valuation continue to support its four-star CAPS status. Currently, ADP even trades at a forward P/E (18.3) discount to Administaff (23.1) and another Foolish favorite, Paychex (21.6).                           

CAPS member TMFMMTInvestor elaborates on the bull case:

Well run company. Inflation hedge: growing dividend that's easily covered by earnings and [free cash flow] and they earn a substantial amount of income on their float. They're diversifying their business and have a lot of room to penetrate into overseas markets. Risk of under-performance in the short run due to low interest rates and sustained high unemployment.
