How Will S&P Global Stock React To Its Upcoming Earnings?
S&P Global (NYSE:SPGI) is set to report its earnings on Thursday, October 30, 2025. The company has $151 Bil in current market capitalization. Revenue over the last twelve months was $15 Bil, and it was operationally profitable with $5.8 Bil in operating profits and net income of $4.0 Bil. While a lot will depend on how results stack up against consensus and expectations, understanding historical patterns might just turn the odds in your favor if you are an event-driven trader.
There are two ways to do that: understand the historical odds and position yourself prior to the earnings release, or look at the correlation between immediate and medium-term returns post earnings and position yourself accordingly after the earnings are released.

Correlation Between 1D, 5D and 21D Historical Returns
A relatively less risky strategy (though not useful if the correlation is low) is to understand the correlation between short-term and medium-term returns post earnings, find a pair that has the highest correlation, and execute the appropriate trade. For example, if 1D and 5D show the highest correlation, a trader can position themselves “long” for the next 5 days if the 1D post-earnings return is positive. Here is some correlation data based on a 5-year and a 3-year (more recent) history. Note that the correlation 1D_5D refers to the correlation between 1D post-earnings returns and subsequent 5D returns.
| History | 1D_5D Returns | 1D_21D Returns | 5D_21D Returns |
|---|---|---|---|
| 5Y History | 53.2% | 28.8% | -14.5% |
| 3Y History | 77.2% | 21.1% | -11.7% |
Is There Any Correlation With Peer Earnings?
Sometimes, peer performance can have an influence on post-earnings stock reaction. In fact, the pricing-in might begin before the earnings are announced. Here is some historical data on the past post-earnings performance of S&P Global stock compared with the stock performance of peers that reported earnings just before S&P Global. For fair comparison, peer stock returns also represent post-earnings one-day (1D) returns.
| 1D Return | Peer Post-Earnings 1D Return | |
|---|---|---|
| SPGI Earnings Dates | SPGI | MCO |
| 7/31/2025 | 4.1% | 1.5% |
| 10/24/2024 | -3.5% | -0.2% |
| 7/30/2024 | -0.3% | 1.4% |
