Some quick Googling led me to http://www.alcor.org/AboutAlcor/patientcaretrustfund.html

The investment into the building & equipment is a little curious, but I think it's defensible: the trust should always have the upper hand over the corporation. Which mostly leaves the regular investments which for 2012 lists it as half stocks/ETFs and half CDs.

I dunno if that's good or bad, but it doesn't sound to me obviously insane or 'loony' (unlike if it were, say, invested into classic comic books and new fine wines).
