The discount chain, which sells most of its products for under $10, posted a 36% jump in third-quarter profit and forecast fourth quarter earnings in line or even above analysts' estimates. The company earned $87.7 million during the quarter, or 62 cents per share, compared with $64.7 million, or 46 cents per share, a year ago. Analysts expected earnings of 59 cents. Looking forward, the company expects fourth-quarter earnings in the range of 39 cents to 43 cents a share, while analysts are for a profit of 39 cents.
