I quickly looked at their financials. They lose about $15M per year, have $20M in the bank and last reported quarter had $0 in revenue ($200K for prior 9 months). They operate in a space that looks askance at companies that aren't financially stable. So, why is this a good company?
It's a long term play at best. They have some interesting technology that promises to speed up networking and it looks like it will likely be inexpensive when it's produced in quantity.
I own some stock, but it's a tiny slice of my holdings. It's a company that may become something, or it may fold.
