6 Red Days In A Row: GLOBALFOUNDRIES Stock Is Down 18%
A persistent slide in the semiconductor stock is now at odds with its longer-term performance, raising questions about its fundamental footing.
GLOBALFOUNDRIES (GFS) Inc. manufactures integrated circuits. The stock has now moved LOWER for 6 consecutive trading days, a cumulative loss of 17.5% that has erased about $6.8 billion from the company’s market value.
The company manufactures a range of semiconductor devices, including microprocessors, mobile application processors, baseband processors, network processors, radio frequency modems, microcontrollers, power management units, and microelectromechanical systems.
GFS Versus The S&P 500, Streak, and Beyond
Here is how GFS stock stacks up against the S&P 500 over the streak and the periods around it:
| Return Period | GFS | S&P 500 |
|---|---|---|
| 1D | -1.3% | -1.0% |
| 6D (Current Streak) | -17.5% | -1.1% |
| 1M (21D) | -28.0% | -0.7% |
| 3M (63D) | 14.2% | 5.9% |
| YTD 2026 | 64.8% | 8.9% |
| 2025 | -18.6% | 16.4% |
| 2024 | -29.2% | 23.3% |
| 2023 | 12.5% | 24.2% |
What do the fundamentals say about this price move?
The recent decline contrasts with a strong longer-term run, as the stock has returned +43.7% over the trailing twelve months. The data shows a company trading at a premium, with a price-to-earnings multiple of 41.0 versus an S&P 500 median of 24.4. This valuation is set against revenue growth of 0.8% over the last twelve months, compared to a market median of 7.5%. Operating margin is also below the median at 12.1%.
This is largely the stock’s own story; the S&P 500 returned -1.1% over the same period. Such streaks are not unusual in the current market, with 38 S&P 500 stocks on losing streaks of three days or more.
How should I treat a streak like this?
A streak is not a signal to buy or sell. It is a measure of sustained attention and momentum, forcing a fresh look at the relationship between a company’s price and its underlying business. The market has repriced this stock lower for six straight sessions.
The disciplined response is to use that fact as a starting point. The numbers here allow you to compare the new price against the company’s growth, margins, and valuation relative to the broader market, which is the necessary work of investing.
If the drop has you weighing an entry, resist buying a falling price alone. Our Buy the Dip screen ranks the marked-down names where growth and cash generation still support a recovery.
Those watching the group rather than this one name have another route: a semiconductor ETF like SOXQ owns the whole group. That way no single company’s next surprise decides the outcome.
GFS Has Fallen 62% From A Peak Before
A stock that falls day after day is a live lesson in what single name exposure feels like.
