In short

The signal is weak on S&P Global (SPGI), with a unanimous vote of 3/3 and a deterministic score of +1,00. This weak intensity stems from the silence of the fundamental layer on the scope that follows the divestiture of Mobility, from the US estate penalty, and from the absence of any new fact since the 31/08 verdict.

Current signal: weak (vote 3/3)
Deterministic score: +1.0 → signal expected by the scale : weak (September 10, 2026)
Layers: fundamentals : neutral, price : positive, risks : positive

Triggered rules

Rule	Weight
favors robust fundamental health (high Piotroski F-Score)	+1.5
penalizes direct holding of US securities in a CTO (US estate tax at death), favors a UCITS ETF domiciled in IE	-1.0
moderately favors an asset with robust operating profitability (RMW factor), cross-check with accounting quality (possible manipulation)	+0.5

Thesis

S&P Global combines a structural competitive advantage, between the rating agency oligopoly and contractual indices, for a valuation brought down to 21,4 times expected earnings. The stock also contributes a measurable diversification effect, with volatility reduced by 5,6 %. The fundamental component remains silent by contrast on the scope that follows the divestiture of Mobility, its confidence is weak, and the US estate penalty (-1,0) caps the deterministic score at +1,00. No new fact has occurred since the 31/08 verdict, and the BCE meeting of 10/09 should bring the decisive element.

Bull case

The bullish argument rests on discounted quality. The forward PER stands at 21,36 (Yahoo, 02/09), far below a stale estimate situated between 28 and 32 times. The high Piotroski score (+1,5), the quality (1,8) and low volatility (3,4) exposures confirm a defensive profile, and the stock furthermore contributes a genuine diversification effect.

Bear case

The bearish argument rests on the monetary regime. The stock is a long-duration asset in a restrictive environment, where rate-sensitive stocks are penalized. The Fed, under Warsh, keeps its rates between 3,50-3,75 %, and inflation of 3,40 % remains above target. The accounting data are stale, with earnings forecasts, margins, and the impact of the Mobility divestiture unverified. Finally, the hidden concentration with MA and V within correlation group 6 constitutes a further risk.

Scenarios

The bullish scenario (35 %) assumes an accommodating BCE on 10/09 and a downward trajectory of Fed rates. The central scenario (45 %) corresponds to a movement without a clear direction, the thesis remaining suspended until the T3 publications. The bearish scenario (20 %) corresponds to a break of the 200-session moving average, which would invalidate the bullish reading.

Risks

The risks are of three kinds. The restrictive regime, with Fed rates between 3,50-3,75 % and inflation of 3,40 % above target, penalizes a long-duration asset. The accounting information remains stale, with the forecasts, the margins, and the impact of the Mobility divestiture unverified. Finally, the hidden concentration with MA and V in correlation group 6 and the US estate penalty weigh on the score. A break of the 200-session moving average would constitute the invalidation signal for the thesis.

Frequently asked questions

What is the current signal on S&P Global and what score is associated with it?

The signal is weak, with a unanimous vote of 3/3 and a deterministic score of +1,00. The reduced valuation and the structural competitive advantage support the thesis, but the fundamental layer remains silent on the post-divestiture scope of Mobility and the US estate penalty (-1,0) caps the score. No new fact has occurred since the 31/08 verdict, which maintains a signal of weak intensity.

Why is the valuation considered discounted?

The forward PER stands at 21,36 according to Yahoo as of 02/09, far below a stale estimate of 28 to 32 times. The retained thesis mentions a valuation of 21,4 times expected earnings. This discount comes with a high Piotroski score (+1,5) and quality (1,8) and low volatility (3,4) exposures, which outlines a defensive profile at a reduced price.

Which events could cause the thesis to evolve?

The BCE meeting of 10/09 constitutes the immediate catalyst, an accommodating tone favoring the bullish scenario while a restrictive tone would support the bearish scenario. The T3 2026 publications will then update the forecasts, the margins, and the impact of the Mobility divestiture, data that are currently stale. No condition of the 31/08 verdict has been lifted so far.

What are the main risks identified?

Three risks stand out. The stock is a long-duration asset in a restrictive regime, with Fed rates between 3,50-3,75 % and inflation of 3,40 % above target. The accounting data are stale after the Mobility divestiture. Finally, a hidden concentration exists with MA and V within correlation group 6. A break of the 200-session moving average would invalidate the thesis.

What does the competitive advantage of S&P Global consist of?

The advantage rests on an oligopoly of rating agencies and on contractual indices, two activities with high barriers to access. These structural characteristics explain the diversification contribution of the stock, volatility being reduced by 5,6 %. The defensive profile is confirmed by the quality (1,8) and low volatility (3,4) exposures.
