During that period, the stock dropped to as low as $13. Today, it is back at the $20 level with no fundamental improvements within the company. Even more disappointing is the fact that management does not appear to have a firm handle on how to fix its issues. From an investment standpoint, the stock sports a price-to-earnings ratio of 51 while both Cisco and HP offer better value with P/Es of 12 and 7, respectively. For Riverbed to justify this level it has to show that it can consistently maintain its gross margins and product margins, which have been on a decline recently. I just don't see how it can do it. Meanwhile it would seem that the market continues to ignore these challenges and yet expects more from Riverbed and F5 while Cisco and HP (although not as dynamic) present better value, while also offering some safety by providing decent dividends yields.
