Institutional holders with a total value over $ 100 million file form 13F with the SEC. I was aware that Asset Management Group had 24.000 SRGE shares. Asset Management Group has a total market cap of $ 260 million in all their investments. They never bothered to sell SRGE so they still have SRGE in their portfolio. I can't see filings older than 4 years ago, but they've had SRGE shares at least since 08-14-2013. Even if the amount of SRGE shares is still small, they still have them and that's what matters.
