Shares of S&P Global Inc. SPGI have gained 16.5% year to date, outperforming 1.8% rise of the industry it belongs to. Let’s delve into factors that have contributed to the company’s outperformance.Consecutive Earnings & Revenue BeatS&P Global reported back-to-back earnings and revenue beat in the last six quarters. While the bottom line gained from revenue growth and benefits of productivity initiatives, the top line performed well on the back of strength across all segments, namely S&P Global Ratings, S&P Global Market Intelligence, S&P Global Platts and S&P Dow Jones Indices.Upbeat 2020 EPS GuidanceS&P Global raised its full-year adjusted EPS guidance to the range of $11.30-$11.45 from the prior guidance of $10.75-$10.95. The current Zacks Consensus Estimate of $11.46 lies above the raised guidance.Strategic Acquisitions Bode WellAcquisitions have been a key growth strategy for S&P Global, helping it continuously innovate, increase differentiated content and develop new products.In 2020 so far, the company has completed the acquisitions of ESG Ratings Business (from RobecoSAM) and Greenwich Associates LLC. While ESG Ratings Business will boost the company’s position as a premier resource for essential ESG data, ratings, benchmarks and insights, Greenwich will complement its existing portfolio of products and expand its offerings to new segments across financial services, including commercial banks, and asset and wealth managers.In 2019, the company acquired 451 Research, Canadian Enerdata, Live Rice Index and Orion technology center. 451 Research is likely to have strengthened S&P Global Market Intelligence's emerging technology expertise and offerings. Canadian Enerdata enhanced S&P Global Platts division's energy-analytical capabilities and strengthened its foothold in the North American natural gas market. Live Rice Index is a great addition to Platts’ global agriculture offering. Orion technology center provides the company’s employees with access to the latest technologies and global communications infrastructure.The company is expected to continue adding advanced technology and data sets through acquisitions, which in turn should boost its top- and bottom-line growth.Zacks Rank and Stocks to ConsiderS&P Global currently carries a Zacks Rank #3 (Hold).Some better-ranked stocks in the broader Zacks Business Services sector are ManpowerGroup MAN, Insperity NSP and BG Staffing BGSF, each carrying a Zacks Rank #2 (Buy).
