Quote from FredBloggs:
note that zb is also fairly low. its also interest rate based.
value is more definite compared to the others, so u wont see the ranges u will in other futures. there is more certainty - if such a thing exists - so u wont see the sort of price discovery u r used 2.
so there wont be as many price/time opportunities.
given that ge is a shorter time span than zb (ge = only 3 months) and that clever money is concerned with long term survival - change is magnified in time - as you will see in zb vs ge, and also ge front vs ge back months.
in other words, long term interest rates (zb) will change/magnify more so than short term rates (ge), as short term rates are tied to current conditions.
is that clear?
this is only my view - others may know more
