S&P Global (SPGI) is back in focus after third quarter earnings on 27 October 2026, with higher reported sales, net income and updated full year guidance drawing fresh attention to the stock.
S&P Global’s recent update landed after a sharp 18.4% 1 month share price return and a 14.6% 3 month gain, even though the stock remains down 8.8% on a year to date share price basis and has produced a modest 0.5% 1 year total shareholder return. This suggests momentum has picked up again as investors reassess the earnings strength, guidance tweaks and ongoing buyback activity.

S&P Global now trades below average analyst targets even after the recent jump, which leaves a simple puzzle: Is the discount a sign of lingering market caution that still makes sense given the guidance tweaks?
Most Popular Narrative: 10% Undervalued
On the most followed view, S&P Global screens about 10% below its narrative fair value of $520.30, compared with the latest $467.80 close. This puts the recent price jump against a longer arc built around data, ratings and AI driven workflows.
The sustained growth in the Vitality Index as a marker of new product contribution is now paired with rapid uptake of AI enabled distribution, including a large number of MCP connectors and a 5x increase in API and LLM calls for two consecutive quarters, which can drive higher enterprise data revenue.

Another View: What Multiples Say About S&P Global
The story looks different when you step away from narrative fair value and look at simple earnings multiples. S&P Global trades on a 26x P/E, very similar to peers at 26.7x, yet well above its own fair ratio of 17.1x. That gap points to valuation risk if sentiment cools.
