HomeAway, Inc. (AWAY), the leading online website for the vacation rentals, rose 46.2% in the fourth quarter. HomeAway reported strong results that beat street estimates for sales and cash flow and posted a sequential acceleration in listing growth. The company recently launched a new service called Pay Per Bookings (PPB), and early results were encouraging. We believe PPB will provide nice incremental growth, not cannibalize, the core subscription business and increase the company's overall opportunity and growth rate. We continue to consider HomeAway an industry leader that is in the early innings of converting a traditional business to a digital Internet approach, and we think cash flow can grow dramatically over time.
