Full disclosure, I've been accumulating CWE for a while now, and picked up some SHE in the recent dip. I will be holding until we see which way the wind blows in the USA, so to speak.
I don't see CWE and SHE being direct competitors at this stage. They each have own IP and target markets; I believe CWE has the better technology but it also comes at a much higher price point. The USA is known for favouring local technology in tenders and while SHE is Australian owned it has close ties and CWE has shown little interest in the American market.
A much more threatening company is
Ocean Power Technologies (Nasdaq:OPTT) with several operating systems in the USA already. Given their poor performance over the last year, though, including pulling out of a AU$233M project off of Victoria I don't know how well they are able to put together a bid for a good sized tender.
It is a pretty safe bet that we will see a number of new wave energy project on US shores; the hope is Australia's and SHEs close ties will be enough to weather the right wing sentiment emerging over there when the tenders go out.
Regardless I think we can all agree that the recent milestones have not yet been reflected in the share price... If it rises past 5c again the finger will be getting itchy, though.
