On CAPS, 96% of the 1,404 members who have rated Paychex believe the stock will outperform the S&P 500 going forward. These bulls include StockTradingFool and All-Star Nittany95, who is ranked in the top 5% of our community.

Just a few months ago, StockTradingFool noted that Paychex "is one of only two major companies who provide payroll and HR services to small and mid-sized businesses." Our CAPS member concludes: "It currently pays a 4.8% dividend and has no debt, and its business should take off as the economy recovers." Since that pitch was written, the stock has risen, pushing the dividend yield down.

Paychex's massive scale, focus on small- to mid-sized businesses (ADP shoots for the big fish), and high customer retention rates drive cash flows that are too tough for Fools to ignore. In fact, Paychex's three-year average cash king margin (28.2%) is higher than that of payroll services foes ADP (16.9%) and Administaff (3.3%).

CAPS All-Star Nittany95 elaborates on the bull case:

They will benefit from three trends -- 1) a pickup in employment, particularly by small business, 2) a continued move toward outsourcing of administrative duties by HR departments, and 3) Inflation/rising interest rates. The first two will drive top-line growth in their main businesses. The Third will growth in their interest income on funds held for clients. While the turmoil in the current credit markets is delaying the pickup in rates, it will eventually happen. When it does, [Paychex] growth will far outpace the rest of the industry. Add to the growth a solid balance sheet and you have a pure play winner.
