Constellation Brands Stock: 11 Straight Red Days, Down 9.8%
A long losing streak for this stock is prompting a closer look at where its underlying business and valuation currently stand.
A persistent slide in Constellation Brands (STZ) stock has erased about $2.1 billion from the company’s market value. The shares have now moved lower for 11 consecutive trading days, a streak that has produced a cumulative loss of 9.8% and left the company’s market value at about $20 billion.
For anyone holding the stock, this kind of sustained selling pressure forces a fresh look at the business itself.
How The Streak Stacks Up Against The S&P 500
Here is how STZ stock stacks up against the S&P 500 over the streak and the periods around it:
| Return Period | STZ | S&P 500 |
|---|---|---|
| 1D | -0.1% | -0.2% |
| 11D (Current Streak) | -9.8% | 0.7% |
| 1M (21D) | -13.7% | -0.5% |
| 3M (63D) | -18.3% | 2.3% |
| YTD 2026 | -16.5% | 12.1% |
| 2025 | -36.0% | 16.4% |
| 2024 | -7.1% | 23.3% |
| 2023 | 5.8% | 24.2% |
Is This Selling About The Stock Or The Market?
This move appears to be specific to Constellation Brands. Over the same 11 trading days, the S&P 500 returned +0.7%. The streak’s length is also notable, as no other S&P 500 stock is currently on a losing streak of 11 days or more.
The sell-off gained momentum as several brokerages slashed their price targets, reflecting deeper, year-long strain across the company’s top line. Revenue over the last twelve months declined 10.5%, while the median for S&P 500 Consumer Staples stocks was growth of 4.3%.
While its operating margin of 31.3% is high compared to the 15.2% median, its price-to-earnings multiple of 11.6 is well below the peer median of 21.6. Constellation Brands stock trades at about $112.77 a share as of 9/29/2026.
What Does A Long Streak Actually Tell An Investor?
A streak is information, not an instruction. It tells you that a stock has sustained momentum and attention, in this case to the downside. It is not, by itself, a signal to buy or sell. The disciplined move is to use the new price as a reason to check your thesis. You can start by weighing the risks of a shrinking business against an increasingly discounted valuation.
A slide like this poses an obvious 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.
Prefer the theme to this single name? A consumer staples ETF like XLP holds the whole group, not the single stock. 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.
