NEW YORK (TheStreet) - Whole Foods Market shares rose roughly 3.1% to $37.68 on Tuesday ahead of Wednesday's earnings report, but it's unclear what caused the stock to pop. The stock has been beaten down 23.5% since its second-quarter earnings report, when the company slashed its guidance. Whole Foods forecast that its annual per share earnings would range between $1.52 a share and $1.56 a share.
