I graphed Ag price for the last 20yrs, buying for the last
5yrs. Ag price comes down at constant slope from
1989 to 1991 then up at constant slope from 1991 to
1999, then back down till 2001. Price grows exponentially
from 2001 to 2009 (to $18.20). Wanders down to $9.50
grows exponentially to current price of $28.
Note mess between 1989 and 2001 -- thus I draw the rule:
if fed gets queer, buy metal
Ag will drop again to a higher low, then rip up to
a higher high (how high?) .
