A 5-Day Winning Streak Has Entegris Stock Up 36%

Here is how ENTG stock stacks up against the S&P 500 over the streak and the periods around it:
| Return Period | ENTG | S&P 500 |
|---|---|---|
| 1D | 0.7% | -0.2% |
| 5D (Current Streak) | 36.0% | 5.6% |
| 1M (21D) | 7.8% | 2.9% |
| 3M (63D) | -2.4% | 6.4% |
| YTD 2026 | 73.2% | 12.8% |
| 2025 | -14.6% | 16.4% |
| 2024 | -17.1% | 23.3% |
| 2023 | 83.5% | 24.2% |
The stock’s price has outpaced its fundamentals.
This recent performance is largely specific to Entegris. Over the same 5 trading days the S&P 500 returned +5.6%, so the streak is mostly this stock’s own story, not the market’s. While such runs are not unique, 133 S&P 500 stocks are currently on winning streaks of 3 days or more, the valuation picture warrants a closer look.
ENTG trades at a price-to-earnings multiple of 72.8, well above the S&P 500 median of 24.1. This premium multiple comes alongside recent top-line growth that trails the broader market. Revenue over the last twelve months grew 3.2%, compared to an S&P 500 median revenue growth of 7.9%. The company’s 3-year average annual revenue growth is -3.8%.
A streak signals attention, not a buy order.
A winning streak is powerful information. It tells you that a stock has momentum and has captured the market’s focus. It is not, however, an instruction to act. The disciplined response is to use the new, higher price as a prompt to re-examine the underlying business.
The core question is whether the company’s future prospects justify the market’s current enthusiasm. The valuation and growth figures provide a starting point for that analysis, weighing strong operating margins against a rich multiple and lagging sales growth.
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.
And for anyone who would rather back the theme than one company’s story, a semiconductor ETF like SOXX owns the whole group. It is still a concentrated bet on that one theme, though, which is exactly the gap the portfolio below closes.
Streaks End. Discipline Compounds
A run like this is genuinely useful information: something about this business has the market’s full attention. But streaks are where discipline gets tested, because the urge to chase strength is strongest right before it pauses.
The Trefis High Quality (HQ) Portfolio channels that urge into a system: roughly 30 businesses selected for consistent cash generation, strong margins, and resilient balance sheets, sized and rebalanced with rules rather than excitement. 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. Enjoy the streak; own the process.
