Yes at some point I've cross-referenced the board members of where I work to see where else they sit. It's obviously much harder to track their investments (unless it's insider buys/sells) but if they used to be C-suite or sit on the board of some company that's majority owned by a REIT, it's hard not to draw conclusions.

It's definitely a rabbit hole that goes deep and one runs the risk of ending up with a spiderweb of red threads on their wall :)
