#3 Supervalu
Ticker: SVU
YTD stock performance: -66%
Market cap: $579 million
Fortune 500 rank: 75

Supervalu investors are still waiting for a turnaround. In 2011, the company lost $1.5 billion, and it was one of the worst performers in the S&P in the first quarter of 2012. This year, shares plunged again. Still, it won't be one of the biggest losers in the S&P 500 ... but that's only because it was removed from the index altogether in April.

Supervalu (SVU, Fortune 500) operates several major grocery chains, including Jewel-Osco, Save-a-Lot and Albertsons. The company has been hit hard in recent years by fierce competition from Wal-Mart and Target (TGT, Fortune 500). Supervalu ousted its CEO after a brutal earnings report in July. Profit for the quarter fell 45% to $41 million. The stock plunged 49% on the news.

While a genuine turnaround now seems like a long shot, there have been rumors that someone may purchase the chain operator -- or at least parts of it. Analysts say it's unlikely the company will be bought by another grocery store chain. The little interest there is comes from Cerberus Capital, which would likely buy it to break it up.
