No insider buys shown on Insider Monkey. It's really hard to tell unless they're revealed in some sort of filings or someone mentions it in a public setting (i.e. conference).
My brokerage shows that 2.65% of the o/s is held by institutional investors.
I don't know of any insider buying myself and I have no way of checking either. You can look at any posters recent posts in their profile and see what they tend to post like on other boards.
