What happened

Week to date, shares of Hain Celestial Group (HAIN -1.30%) were down 17% as of Friday morning, according to data provided by S&P Global Market Intelligence. Investors were disappointed with the company's earnings results released earlier this week. Sales were down again, and management guided for more of the same in the near term.

Year to date, the stock is down 11%, extending the stock's multiyear slide to 48% over the last five years. 

So what

Hain is a leading supplier of organic and natural food brands. While the company saw strong sales of Greek Gods yogurt and Earth's Best brands in the U.S., overall sales fell 9% year over year. The performance stands out against larger brands like PepsiCo's snack foods, which reported a double-digit increase in sales last quarter. 

The top-line pressure is hitting Hain on the bottom line, too, with adjusted profit falling to $7.4 million from $29.7 million in the year-ago quarter. 

Now what

With management forecasting full-year sales to be down between 3% and 4% year over year, the stock is not likely heading higher anytime soon.

Inflation has hurt even the strongest consumer staples brands over the last year. Coca-Cola and PepsiCo have experienced declining volumes in certain categories. But these larger companies are handling it better with price increases, which is keeping their sales growing at solid rates through this challenging economy.

Hain's premium brands don't seem to be as resistant to recessionary forces in the economy. Investors interested in food stocks should stick with the leading grocery brands that have outperformed the market on the back of solid financial results.
