Constellation Brands Stock: 10 Straight Red Days, Down 9.7%

A recent wave of selling has pulled the stock lower amid contracting revenue, even as operating margins remain robust.

A 10-day losing streak in Constellation Brands (STZ) stock has erased about $2.1 billion from the company's market value. The cumulative loss over this period is 9.7%, leaving the company's market value at about $20 billion. For long-term holders, this persistent selling has created a noticeable headwind.

Constellation Brands stock trades at about $112.92 a share as of 9/28/2026.

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:

The selling is largely isolated to Constellation Brands; the S&P 500 gained 0.8% over the same 10-day span. Extended declines of this type are rare across the broader market, with only one other S&P 500 constituent currently on an equal or longer losing streak.

What Do The Business Fundamentals Show?

The data highlights top-line operational pressure alongside a discounted valuation. Revenue over the last twelve months declined 10.5%, trailing the 4.3% median across S&P 500 Consumer Staples peers.

At a price-to-earnings multiple of 11.6, the stock trades well below the sector peer median of 21.8. Still, the company's operating margin over the last twelve months stands at 31.3%, far above the 15.2% sector peer median.

How Should An Investor Treat A Streak?

A long streak is not a signal to buy or sell. It is simply information. It simply reflects persistent selling pressure and heightened market attention. The disciplined response is to use the new attention as a reason to re-evaluate the business against its price. The numbers here provide a starting point for that work.

A drawdown of this scale raises an obvious question: 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.
