CNX Resources Stock: 10 Straight Red Days, Down 13%

A losing streak in this profitable, growing company has drawn investor attention, raising questions about its current valuation.

A 10-day slide in CNX Resources (CNX) stock has erased about $723 million from its market value. The shares have now moved lower for 10 consecutive trading days, a cumulative loss of 13%. For anyone holding the stock, the move has pushed the company's valuation down to about $4.9 billion.

CNX Versus The S&P 500, Streak And Beyond

Here is how CNX stock stacks up against the S&P 500 over the streak and the periods around it:

Has the selling overshot the fundamentals?

The data suggests a disconnect. CNX Resources' revenue over the last twelve months grew 16.2%, ahead of the 12.5% median for S&P 500 Energy stocks. Its operating margin of 39.8% is also above the sector median of 22.9%. The company's three-year average annual revenue growth, however, is 0.9%.

The stock now trades at a price-to-earnings multiple of 5.1, well below the median of 17.2 for its sector peers. This recent decline is specific to the stock; while CNX fell 13%, the S&P 500 lost 1.3% over the same 10 trading days. The sources do not show why the move happened.

A streak is information, not an instruction.

A long streak is a signal about momentum and where the market's attention is focused. It is not a command to buy or sell. The disciplined response is to check the business against its new price, which the numbers here allow an investor to begin doing.

CNX Resources stock trades at about $32.89 a share as of 9/18/2026.

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? An oil and gas ETF like XOP 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.
