Is Kroger Stock Increasing Your Market Risk

For questions about this article or underlying research, email [email protected].

If you own Kroger (KR), or are weighing the stock after its 8.2% rise in the five sessions to October 22, 2026, your position most likely sits alongside capital tracking the S&P 500. Every day the index fluctuates, Kroger's performance blends with the rest of those holdings. So does Kroger add to the risk you already carry, or work against it?

Kroger Stock Has Moved Against The Market

Over the past year, from October 21, 2025, to October 22, 2026, Kroger shares moved against the broader market. A $10,000 holding in Kroger fell about $35 on an average day the S&P 500 rose, and gained about $43 on an average day the index declined. For each 1% the S&P 500 moved over the past year, Kroger tended to shift about 0.71% the other way.

That dynamic does not make Kroger a calm stock. Its volatility, the typical size of its swings over a year, was 29.8%, more than double the S&P 500's 12.7%. While Kroger steadied a broader market portfolio over the past year, the shares brought larger swings of their own.

Will Kroger Keep Moving Like This?

Kroger is reshaping its operations during a period of slow sales growth, which gives investors more to weigh. In September 2026, management lowered its full-year forecast for identical sales without fuel, its measure of sales growth at existing stores, to 0.5% at the midpoint from 1.5%. The company maintained its full-year profit forecast.

Kroger laid out a multi-year plan on October 20, 2026, introducing new long-term targets that run through 2029. Management expects its planned acquisition of Giant Eagle to close in 2027. Separately, Albertsons is seeking $8 billion from Kroger over their failed merger, with a trial looming, news reports said on October 12, 2026.

The direction of Kroger's moves is less settled than their size. From October 2021 to October 2026, the stock's daily moves showed almost no connection to the index, posting a correlation of 0.05, where zero means no link. Moving against the broader market is a recent pattern for Kroger, while its wide swings have persisted longer.

Has Kroger Stock Paid You For Its Swings?

Over the five years from October 23, 2021, to October 22, 2026, Kroger paid you slightly more than the market, but yielded less for each unit of swing. The stock returned 13.5% a year during that window, compared with 12.6% for the S&P 500. Kroger posted an annual volatility of 27.4%, against 17.0% for the index.

Dividing the return by the volatility reveals how much each unit of swing earned: 0.493 for Kroger and 0.741 for the S&P 500. A higher figure means the swings paid better, so the market rewarded you more for each unit of swing.

If the past year's pattern holds, Kroger would trim your gains on the market's up days and soften your losses on its down days. If you already own another grocer, such as Albertsons, your money leans further on how much shoppers spend on food, and holding Kroger adds to that bet rather than spreading it. Kroger is expected to report in December 2026, and its identical sales without fuel are the measure to watch.

Does This Mean You Should Act On KR?

Our purpose is to inform you with unique data so you can make the right investment decisions. That said, betting on a single stock is always risky, no matter which direction you choose.

There is a smarter approach. Since its inception, the Trefis High Quality (HQ) Portfolio has returned 105%, beating the benchmark that combines the three major indices - the S&P 500, S&P Mid-cap, and Russell 2000. And it did so without taking the concentrated risk that comes with do-it-yourself stock picking. If that is how you want to invest, the HQ Portfolio is the place to start.
