Whole Foods shares climbed Wednesday after better-than-expected earnings, and some "Fast Money" traders believe the grocer's stock could continue to rise.
Whole Foods posted fiscal first-quarter earnings of 46 cents per share on $4.83 billion in revenue, topping Wall Street's expectations on both metrics. Despite the beat, its comparable-store sales fell 1.8 percent.
Shares rose about 3 percent in after-hours trading.
"I think there's still growth here. It's not cheap, but it's not expensive," said trader Karen Finerman.
