CME Stock: 8 Straight Green Days, Up 13%
A persistent winning streak for the stock has investors looking closer at the business fundamentals driving the move.
CME (CME) stock has now moved higher for 8 consecutive trading days, delivering a cumulative gain of 13% over the period. That streak has added about $11 billion to the company’s market value, which now stands at about $97 billion.
For anyone holding the stock, the run has more than erased a recent dip; shares have returned +0.2% over the trailing twelve months.
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 | 0.2% | 0.7% |
| 8D (Current Streak) | 12.8% | -0.3% |
| 1M (21D) | 15.9% | 0.1% |
| 3M (63D) | -6.5% | 3.9% |
| YTD 2026 | 0.9% | 9.4% |
| 2025 | 19.8% | 16.4% |
| 2024 | 15.4% | 23.3% |
| 2023 | 31.3% | 24.2% |
Do the fundamentals support this run?
The move appears to be specific to the company, not a broader market lift. Over the same 8 trading days, the S&P 500 returned -0.3%. The streak also stands out in a market where more stocks are falling; just 18 S&P 500 stocks are on winning streaks of 3 days or more, while 88 are on losing streaks.
The buying aligns with some strong business metrics. CME’s operating margin over the last twelve months is 65.1%, far exceeding the S&P 500 median of 18.4%. Its valuation is also in line with the market, with a price-to-earnings multiple of 22.5 against the S&P 500 median of 23.9.
A streak is information, not an instruction.
An extended run of buying is a clear signal of momentum and renewed market attention. It is not, however, a guarantee of future performance, as any streak can end without warning.
The most disciplined response is to use the new price as a prompt to re-evaluate the business. The data on margins, growth, and valuation provides a starting point for deciding whether the current price fairly reflects the company’s financial footing.
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.
Prefer the theme to this single name? A U.S. broker-dealers & securities exchanges ETF like IAI owns the whole group. It is still a concentrated bet on that one theme, though, which is exactly the gap the portfolio below closes.
Momentum Is A Tailwind, Not A Plan
Riding a stock that rises every day feels effortless, and that is precisely the danger: the same momentum that built this run can reverse without notice, and one name’s reversal should never be able to reset your whole year.
That is what the Trefis High Quality (HQ) Portfolio is for: about 30 quality businesses screened for the fundamentals that survive momentum’s mood swings, held with rules. It has a track record of outpacing a benchmark that combines the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000. Watch the runs; own the resilience.
