PriceSmart (NASDAQ: PSMT), an operator of warehouse clubs in Central America and the Caribbean and headquartered in San Diego, announced results for the third quarter on Friday. Judging by the reaction to the stock, I'd say the market wasn't too thrilled by the company's performance. As I write this, PriceSmart shares are down almost 14% on heavy volume in afternoon trading.

Net warehouse sales increased nearly 8%. Total revenue went up by a similar amount. Earnings came in at 30 cents per diluted share. Unfortunately, that means that PriceSmart's bottom line declined by 17%.

Flow International Corp. (NASDAQ: FLOW), which makes industrial waterjet equipment, swung to a better-than-expected fiscal fourth-quarter profit of $13.3 million, or 35 cents per share, helped by a boost in sales due to strong demand and an income tax benefit.

Motor sports company International Speedway Corp.'s (NASDAQ: ISCA) second-quarter profit rose 41% to $26 million, or 52 cents per share.

Apparel and footwear company Wolverine World Wide Inc.
