I would say not cheap and not expensive. Maybe cheaper than overall market.
My own opinion is we're at the top of the first inning with this. Unlike some accusations in other posts, management is fully vested and gets paid not in excess salary or options but rather through stock performance. An ideal alignment if there ever was one.
If memory serves, the ISIG investment was worth more per share at year end than currently, so you may have a mark down on that. I can only imagine the allure of ISIG is 1) huge cash relative to market cap and 2) opportunity to turn around.
So overall I think this one will well outperform the market over the long term and the company 5 years from now will be vastly different than today.
