It took a bit of digging, but I managed to find some very nice
historical graphs of daily prices for Sugar 11 (global) futures:
There are no obvious trends in the data, which isn't surprising. As
far as I know, sugar futures prices are much more affected by external
events such as weather anomalies, consumer spending, crop diseases,
subsidy policies, and competition from other sweeteners, than they are
by internal factors such as the closing of a particular contracts
You can see in the graphs that post-October prices sometimes rise,
sometimes fall, and in some years, stay pretty flat.
A look at the high/low prices for the year also shows an absence of
any obvious patterns in the pricing:
Sugar 11 Months of High/Low prices:
2006: Feb/Jan (through July 2006)
If there's a pattern there, then I certainly can't see it!
More to the point, if there *were* any obvious patterns in the price
trends, then market forces would tend to immediately erase them, as
those buying on the trend, would jack up the current prices for the
futures options, if you see what I mean.
Anyway, I trust this information fully answers your question.
However, please don't rate this answer until you have everything you
need. If you would like any additional information, just post a
