A peculiar thing happened after financial software giant Intuit Inc. (NASDAQ: INTU) reported its third-quarter earnings. Intuit beat analyst expectations, delivering a 10% year-over-year revenue increase to $8.6 billion. It then raised its full-year guidance, projecting double-digit growth in both sales and earnings per share. This is the kind of beat-and-raise report that typically sends a stock climbing. Instead, Intuit's shares plunged by more than 14% in after-hours trading.
