Moody’s Stock Climbs 7.8% On A 7-Day Winning Streak
A steady, multi-day climb has pushed the company’s stock higher, raising questions about its already premium valuation.
Moody’s (MCO) stock has now moved higher for 7 consecutive trading days. The cumulative gain over this period is 7.8%, a move that has added about $6.5 billion to the company’s market value.
That increase brings its total market capitalization to about $90 billion. For shareholders, the run has been a clear positive, but it has occurred while the broader market has been flat to down.

Here is how MCO stock stacks up against the S&P 500 over the streak and the periods around it:
| Return Period | MCO | S&P 500 |
|---|---|---|
| 1D | 0.3% | -0.0% |
| 7D (Current Streak) | 7.8% | -0.9% |
| 1M (21D) | 6.5% | 3.3% |
| 3M (63D) | 14.2% | 2.1% |
| YTD 2026 | 1.4% | 12.1% |
| 2025 | 8.7% | 16.4% |
| 2024 | 22.2% | 23.3% |
| 2023 | 41.5% | 24.2% |
The stock’s valuation now outpaces its strong fundamentals.
This recent climb is the stock’s own story. Over the same 7 trading days, the S&P 500 returned -0.9%. The business itself shows solid performance, with revenue over the last twelve months growing 11.7%, ahead of the S&P 500 median of 8.4%. Its operating margin of 46.1% is also significantly above the 18.5% median for the index.
However, the stock trades at a price-to-earnings multiple of 32.1. That represents a premium to both the S&P 500 median of 23.5 and the 14.8 median for S&P 500 financial stocks. While notable, the run is not entirely unique; 5 other S&P 500 stocks are currently on winning streaks of 7 days or more.
A streak is a signal, not an instruction.
A multi-day run puts a stock on the radar, reflecting momentum and investor attention. It does not, by itself, say whether the stock is a sound investment at its new, higher price. The disciplined response is to re-evaluate the business against its valuation.
The data here allows for that first look: a company with strong margins and growth, but also one that carries a high multiple for its sector. A streak simply provides a reason to check the math.
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.
And for anyone who would rather back the theme than one company’s story, a U.S. broker-dealers & securities exchanges ETF like IAI holds the sector rather than this one name. It is still a concentrated bet on that one theme, though, which is exactly the gap the portfolio below closes.

A streak like this earns a place on your watchlist, and it also earns a question: how much of your outcome do you want depending on one company keeping this up?
