As a long, I wonder the same. I speculate that most are in a wait in see mindset (Q3 and Q4 earnings). Heavy short interest scares people off. People believe there is too much competition in the headphone space for skull to succeed. Only 5 quarters as a public company, so people are skeptical. I think two more quarters of continued growth will substantiate the company and finally draw some investor interest.
IMO, a fantastic buy at these prices and wish I had more powder left.
