It’s low, IMHO of course, because despite the great news, accompanying statements such as “…its first product and demonstrate this prototype by the end of 2016,” projects that irrefutable news, an NRE and/or a significant partnership is still some ways down the TRAB road. So they, traders, can sell at an initial NR prompted SP peak and buyback after they walk it down the hill. In short, they know they have a window of opportunity because they’ve been tacitly told so.
BTW, a few people on this forum have revealed they too hold trading positions so they can make lemonade while they wait for the Champaign to chill (in my case, ginger ale).
