Marathon Petroleum Stock Climbs 13% On A 10-Day Winning Streak
A recent run in Marathon Petroleum (MPC) stock has added about $13 billion to the company’s market value. The move comes from a winning streak that has now lasted for 10 consecutive trading days, producing a cumulative gain of 13% and bringing the company’s market value to about $115 billion.
For any investor holding the shares, this is a significant and rapid appreciation.
The Streak Next To The S&P 500
Here is how MPC stock stacks up against the S&P 500 over the streak and the periods around it:
| Return Period | MPC | S&P 500 |
|---|---|---|
| 1D | 0.4% | -0.5% |
| 10D (Current Streak) | 12.6% | -0.5% |
| 1M (21D) | 25.0% | -1.5% |
| 3M (63D) | 55.2% | 3.4% |
| YTD 2026 | 148.5% | 11.6% |
| 2025 | 19.2% | 16.4% |
| 2024 | -4.1% | 23.3% |
| 2023 | 30.5% | 24.2% |
What do the fundamentals say about this price?
The data presents a mixed case. Over the same 10 trading days, the S&P 500 returned -0.5%, suggesting the move is specific to the stock, not a market-wide trend. The streak’s length is also notable, as NO other S&P 500 stock is currently on a winning streak of 10 days or more.
From a business perspective, revenue over the last twelve months grew 15.0%, ahead of the S&P 500 median of 8.3%. The stock’s price-to-earnings multiple of 13.5 is also below the S&P 500 median of 22.9. However, its operating margin of 7.5% is less than half the S&P median of 18.7%, and its 3-year average annual revenue growth is -0.1%.
How should an investor treat a streak like this?
A streak is information, not an instruction. It signals that a stock has momentum and has captured the market’s attention. It is not, by itself, a reason to buy or sell. The disciplined response is to use the new price as a prompt to re-evaluate the business.
The run-up means you are paying more for the same underlying operations than you were two weeks ago. The fundamental metrics here offer a starting point to decide if that new price is justified by the company’s performance and valuation.
If you are hunting for strength that has more behind it than a hot tape, our Guidance Momentum screen surfaces the names where management raised its own outlook, which is the kind of momentum that tends to persist.
Those drawn to the strength but not the single-name risk have another route: an energy ETF like XLE 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.
One Hot Stock Is A Story. Thirty Sound Ones Are A Strategy
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?
