CME Stock: 7 Straight Green Days, Up 13%
A seven-day run for the exchange operator has investors looking closer at the underlying business fundamentals.
CME Group (CME) stock has now moved higher for 7 consecutive trading days, producing a cumulative gain of 12.6%. That streak has added about $11 billion to the company’s market value, which now stands at about $96 billion.
For anyone holding the stock, this run has been a significant positive turn, especially as the broader market has moved in the opposite direction.
How The Streak Stacks Up Against The S&P 500
Here is how CME stock stacks up against the S&P 500 over the streak and the periods around it:
| Return Period | CME | S&P 500 |
|---|---|---|
| 1D | 0.7% | 1.7% |
| 7D (Current Streak) | 12.6% | -1.0% |
| 1M (21D) | 21.0% | -0.8% |
| 3M (63D) | -6.5% | 4.2% |
| YTD 2026 | 0.7% | 8.6% |
| 2025 | 19.8% | 16.4% |
| 2024 | 15.4% | 23.3% |
| 2023 | 31.3% | 24.2% |
Does the business support this buying?
The data suggests the market is weighing some strong fundamental metrics. CME’s operating margin over the last twelve months is 65.1%, far exceeding the S&P 500 median of 18.4%. Its price-to-earnings multiple of 22.5 sits just under the S&P 500 median of 24.0, suggesting a valuation that is not stretched relative to the market.
Its recent revenue growth of 5.1% trails the median of 7.8%, so this move appears to be the stock’s own story. Over the same 7 trading days, the S&P 500 returned -1.0%. Currently, just 21 S&P 500 stocks are on winning streaks of three days or more, while 36 are on losing streaks.
A streak is information, not an instruction.
A sustained move like this is a clear signal of momentum and heightened market attention. It is not, however, a simple directive to buy or sell. The disciplined approach is to use this moment to re-evaluate the business relative to its new, higher price.
The core questions remain the same: does the company’s performance, particularly its high operating margin of 65.1% and its valuation, justify the price? A streak brings a stock into focus, but the decision to act always comes back to the numbers.
A run like this is worth respecting, and worth testing: the momentum that lasts is usually the kind management itself is underwriting. Our Guidance Momentum screen tracks the stocks whose companies just raised their own forward numbers.
