Dycom Industries Stock: 8 Straight Red Days, Down 29%
After a steep and sustained decline, the data suggests a disconnect between this industrial stock’s price and its underlying business growth.
Dycom Industries (DY) stock has now moved lower for 8 consecutive trading days, a slide that has cut 29% from its share price. That streak has erased about $3.8 billion from the company’s market value, which now stands at about $9.3 billion.
For anyone holding the stock, the decline has been sharp and swift, far outpacing the broader market.
How The Streak Stacks Up Against The S&P 500
Here is how DY stock stacks up against the S&P 500 over the streak and the periods around it:
| Return Period | DY | S&P 500 |
|---|---|---|
| 1D | -0.9% | 0.7% |
| 8D (Current Streak) | -28.8% | -0.2% |
| 1M (21D) | -17.2% | 5.7% |
| 3M (63D) | -42.4% | 2.2% |
| YTD 2026 | -8.8% | 12.9% |
| 2025 | 94.1% | 16.4% |
| 2024 | 51.2% | 23.3% |
| 2023 | 23.0% | 24.2% |
Has the selling gone too far?
The move appears to be specific to the company. Over the same 8 trading days the S&P 500 returned -0.2%. The market may be weighing a business that is growing quickly, as revenue over the last twelve months grew 37.8%, well ahead of the S&P 500 median revenue growth of 8.3%.
Profitability is a different story, with an operating margin over the last twelve months of 7.8%, below the S&P 500 median of 18.5%. After the decline, DY trades at a price-to-earnings multiple of 28.1. This is above the S&P 500 median of 23.3, but in line with the median of 28.3 among S&P 500 Industrials stocks.
A streak is a signal, not a command.
An extended move in one direction is information. It tells you that a stock has captured the market’s attention, and it reflects a powerful short-term momentum. But a streak is not an instruction to buy or sell; it does not, by itself, say whether a stock is now cheap or still expensive.
The disciplined response is to check the price against the business. The fundamental data offers a starting point to assess whether the recent 29% decline reflects a change in the company’s prospects or a shift in market sentiment.
A slide like this always poses the same follow-up: which marked-down stocks are actually worth buying? Our Buy the Dip screen runs that test every day, flagging beaten-down names whose fundamentals still hold up.
Those watching the group rather than this one name have another route: our ETF Scorecard shows how the U.S. industrials funds stack up. It is still a concentrated bet on that one theme, though, which is exactly the gap the portfolio below closes.
A Slide Like This Is Why Diversification Exists
Watching one stock fall day after day is the clearest lesson the market teaches about single-name risk. Whether this particular decline is an opportunity or a warning, the deeper point is the same: no one name should be able to do this to your portfolio.
The Trefis High Quality (HQ) Portfolio is built on that principle: roughly 30 businesses selected for consistent cash generation, strong margins, and resilient balance sheets, sized and rebalanced with rules. 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. Study the slide; spread the risk.
