Just cashed out for 2M. What now?
pg: Here's the conventional advice. Start with it all in cash, in some form you feel is sufficiently safe from disasters.  Gradually over a couple years bleed it into some combination of stocks (by default in a low-cost index fund) and bonds.  The usual rule of thumb is to put your age percentage in bonds.  I.e. at age 30 you should have 30% bonds.
