What Recent Stock Swings Mean for S&P Global’s Market Value in 2025

Reviewed by Bailey Pemberton
Thinking about what to do with S&P Global stock right now? You are definitely not alone. Whether you are weighing a hold, a buy, or just curious, S&P Global remains one of those companies that always seems to be at the heart of market conversations. The company’s recent stock swings say a lot about shifting investor sentiment. Over the past week, the shares have nudged 0.1% higher, but that comes after a bumpy month where the price dropped 11.2%. For the year so far, S&P Global is down 2.5%, and if you zoom out, it is off 8.1% over the last 12 months. Yet, anyone with a long memory will notice that over three years, the stock is up an impressive 66.8%, and it has delivered a solid 49% gain over the last five years.
Some of these shifts reflect broader market moods, especially how investors view risk and long-term growth for finance and data companies. With so many moving parts, the stock’s current valuation is a hot topic. According to our checklist, S&P Global is undervalued in just 1 out of 6 major valuation metrics, earning itself a value score of 1. In the next section, I will break down what that really means, walking through the main ways analysts value a stock like S&P Global, and why the best measure of true value might actually come at the end of this article.
S&P Global scores just 1/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.
Approach 1: S&P Global Excess Returns Analysis
The Excess Returns model provides a different lens on stock valuation. Instead of only looking at profits or dividends, this approach measures how much value a company creates above the minimum return investors demand, known as the cost of equity. Put simply, it examines whether investing in S&P Global’s business generates profits that beat the company’s own cost for using investor funds.
For S&P Global, the numbers are telling. The estimated Book Value stands at $109.37 per share, while analysts forecast a stable Earnings Per Share (EPS) of $18.38, based on a range of future estimates. That compares to a Cost of Equity of $9.30 per share, which means each share is expected to generate an "Excess Return" of $9.07. The firm’s average Return on Equity comes in at a strong 16.33%, and the Stable Book Value is projected to climb to $112.55 per share over time.
Pulling these figures together, the model estimates S&P Global’s intrinsic value per share at $287.43. Compared to the current market price, the discount implied is -68%, indicating the stock is significantly overvalued using this approach.
Result: OVERVALUED
Our Excess Returns analysis suggests S&P Global may be overvalued by 68.0%. Find undervalued stocks or create your own screener to find better value opportunities.
Approach 2: S&P Global Price vs Earnings
The Price-to-Earnings (PE) ratio is a widely used tool for valuing profitable companies like S&P Global because it tells us how much investors are willing to pay for each dollar of earnings. This makes it especially relevant for mature businesses with steady profits.
What the market considers a "normal" or “fair” PE ratio depends a lot on the company’s future earnings potential and the perceived risks. Companies with stronger growth prospects or lower risks often command higher PE ratios, while lower growth or riskier businesses tend to see lower multiples.
S&P Global currently trades at a PE ratio of 36.8x, placing it well above the Capital Markets industry average of 25.7x and its immediate peer group average of 31.6x. Simply Wall St’s proprietary “Fair Ratio” for S&P Global comes in at 20.2x. This figure is based on a detailed assessment of the company’s earnings growth, profit margins, market cap and risks specific to its industry.
The Fair Ratio offers a more complete picture than just using straight industry or peer averages because it adapts to the company’s unique traits and risk profile. Comparing S&P Global’s current PE to its Fair Ratio suggests the stock is quite a bit more expensive than its fundamentals alone might justify.
Result: OVERVALUED
PE ratios tell one story, but what if the real opportunity lies elsewhere? Discover companies where insiders are betting big on explosive growth.
