Good point.
Just comparing:
SP forw PE (3yrs) avg. backw PE (10 yrs)
OCA 79 7.9 10.0
RYM 581 5.2 8.7
So yes, both are cheap as chips, but Ryman is at current prices still more attractive.
But I am sure many people prefer to wait until price is up again above their favorite indicator ... just to be safe :) ;
