Approach 1: S&P Global Excess Returns Analysis

The Excess Returns model looks at how much value a company can create above the return that shareholders require. Instead of focusing only on current profits, it compares the return generated on equity to the cost of that equity, then capitalizes those surplus returns into an intrinsic value per share.

For S&P Global, the model uses a Book Value of $105.31 per share and a Stable EPS of $21.16 per share, based on weighted future Return on Equity estimates from 5 analysts. The Average Return on Equity is 19.77%, while the Cost of Equity is $8.49 per share. This leads to an estimated Excess Return of $12.67 per share. Stable Book Value is set at $107.06 per share, using weighted future Book Value estimates from 4 analysts.

On these assumptions, the Excess Returns model points to an intrinsic value of about $395.77 per share, compared with the current share price of about $413.34. That implies the stock screens as roughly 4.4% overvalued under this framework, which is a relatively small gap.

Result: ABOUT RIGHT

S&P Global is fairly valued according to our Excess Returns, but this can change at a moment's notice. Track the value in your watchlist or portfolio and be alerted on when to act.

Approach 2: S&P Global Price vs Earnings

For a profitable company like S&P Global, the P/E ratio is a useful way to think about what you are paying for each dollar of earnings. It links directly to what the business is currently generating rather than only what its assets are worth or how much revenue it brings in.

In general, higher expected earnings growth and lower perceived risk can justify a higher P/E, while slower growth and higher risk usually line up with a lower, more conservative multiple. S&P Global currently trades on a P/E of about 25.6x. That is below the Capital Markets industry average P/E of about 39.2x, but slightly above the peer group average of about 24.7x.

Simply Wall St’s Fair Ratio for S&P Global is 18.6x. This Fair Ratio is a proprietary estimate of what the P/E might look like given factors such as earnings growth, profitability, industry, market cap and risk profile. Because it blends these company specific drivers, it can be more tailored than simply lining up the stock against peers or the broad industry. Comparing the current P/E of 25.6x with the Fair Ratio of 18.6x suggests the shares trade at a premium to this benchmark.
