7 Red Days In A Row: GLOBALFOUNDRIES Stock Is Down 19%
A multi-day slide in the semiconductor maker’s stock puts a spotlight on its premium valuation and underlying growth.
GLOBALFOUNDRIES Inc. manufactures integrated circuits, which enable various electronic devices that are pervasive. The stock has now moved lower for 7 consecutive trading days, a cumulative loss of 18.5%.
That streak has erased about $7.2 billion from the company’s market value, which now stands at about $32 billion.

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 | -1.2% | -0.2% |
| 7D (Current Streak) | -18.5% | -1.3% |
| 1M (21D) | -29.4% | 0.3% |
| 3M (63D) | 3.9% | 4.5% |
| YTD 2026 | 62.9% | 8.7% |
| 2025 | -18.6% | 16.4% |
| 2024 | -29.2% | 23.3% |
| 2023 | 12.5% | 24.2% |
What does the data say about this price move?
The decline appears specific to the company. Over the same 7 trading days the S&P 500 returned -1.3%, so the streak is mostly this stock’s own story, not the market’s. Such streaks are not unusual; currently, 42 S&P 500 stocks are on losing streaks of 3 days or more.
The market may be weighing the company’s premium valuation against its recent performance. GFS trades at a price-to-earnings multiple of 40.5, versus an S&P 500 median of 24.3. Meanwhile, its revenue over the last twelve months grew 0.8% against a median of 7.5%, and its operating margin is 12.1%, below the S&P 500 median of 18.4%.
How should I think about a streak like this?
A streak is a data point, not a directive. It tells you that a stock has sustained momentum and captured market attention, but it does not tell you whether the new price is justified or where the price goes next.
The disciplined response is to use the new information as a prompt to re-evaluate the business fundamentals against the stock’s valuation. The numbers here provide a starting point for that assessment.
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. GFS itself has fallen 62% from a peak within the past five years, and a fall like that lands very differently when one position carries too much of your wealth.
