The seasonal charts
depicted in this publication are a pictorial presentation of the normal
behavior of the markets. The
charts are made for specific contract months, so that the trader can see
the behavior of the specific contract they are looking at.
This detail is of the utmost importance in markets with new and old
crop contracts, such as the agricultural commodities.
The charts depict
behavior on a relative basis, meaning the actual prices are not forecast,
just the relative position of the market versus its contract high and low.
On the seasonal charts, the high is depicted as 1.0, or 100%, while
the low is depicted as 0.0 or 0%. Using
an 11 month period, we rank all 15 years analyzed in terms of where each
day falls as a percentage of the highest and lowest price of that 11 month
period for each specific year. These
prices are then averaged and the average is depicted in our charts.
To read the chart, just
follow the chart and remember that 1.0 is the contract high for the 11
months displayed, and 0.0 is the contract low.
For example, assume you
are following the September 1999 Bean Oil futures. Examining the chart below, you can assess that on average
Soybean Oil tends to rally from late November into late December, breaking
slightly into the New Year. From
its January low, September Bean Oil usually rally with only moderate
corrections into late May. By
the second week of May, September Bean Oil typically makes its seasonal
high, breaking quite violently in June and July, to finally make its
seasonal bottom during the third week of August.

Knowing that Soybean Oil
tends to make its high in mid to late May, the trader holding long
positions should operate with greater caution, while a trader looking to
establish short positions may wish wait until this period to establish
those positions. The seasonal
charts are an extremely useful tool, which allow the futures speculator to
plan in advance his/her strategy, using historical turning points to aid
other forms of analysis.
