Here's an unusual sign of health in the troubled world of retail: BJ's Wholesale Club is going public again.
BJ's, an East Coast competitor of Costco (COST) and Walmart's (WMT) Sam's Club, has 215 stores in 16 states. It was publicly traded until 2011, when two private equity firms bought it in a deal valued at $2.8 billion.
It's not unusual for private equity to buy a retail company. But very often, as in the cases of Sports Authority and Toys "R" Us, the chain ends up filing for bankruptcy, not going public again.
