MERU A year ago this was a 27 dollar stock...
...and their products and services revenues are up 13% over that time frame, while the stock dropped to the $3's. Even if there isn't a specific event that insiders are expecting, they could be buying because they are witnessing the increase in sales they were expecting from their recently expanded sales force. This is from their last earnings release-
"2011 was a year of building for Meru," said Ihab Abu-Hakima, president and chief executive officer, Meru Networks. "We have doubled our sales headcount from the end of 2010, with the majority of this headcount joining since the beginning of the fourth quarter. In addition, we have significantly expanded our product portfolio, and increased our marketing investment. We expect to reap the benefit of these investments beginning in the second half of 2012 as our expanded sales headcount begins to reach full productivity and the BYOD-driven, worldwide mobile workforce continues to expand, increasing the demand for seamless, secure, reliable access to enterprise wireless networks. Meru's innovative approach is designed to enable organizations to meet the demands of their high density mobile environments where business-essential execution increasingly depends on all wireless mobile edge networks."
