In this Observation, we are going to use the
Reuters/CRB Futures Index (CRB) as our proxy for commodity
prices. We will point out what might be a repeating price
pattern.
We began our analysis with a simple 20% swing
line chart of our daily CRB price data back to 1956. Upon
examination of that chart, we were struck with the similarities
of the price patterns of the CRB in the late 1970s/early 1980s
and the current pattern that has been unfolding since 1999. We
ran the chart past our good friend Don, and he suggested going
back one more pattern to the late 1960s/early 1970s.
Here is a monthly chart (updated through March
18, 2005) with swings overlaid in orange and labeled with dates
and prices of tops and bottoms.

The
following chart shows what we feel appears to be three repeating
patterns. Each pattern is color coded orange teal or black and
numbered 1, 2 3 and 4.

The
statistics for the three patterns is shown in the following
table:

Discussion
Notes:
-
Each
pattern starts with a 1, 2, 3 up/down “set-up” followed by a
strong thrust from 3 to 4.
-
The
orange cycle “set-up” was the beginning stages of the 1970’s
inflation.
-
The
orange cycle thrust from 3 to 4 includes the first oil price
shock in late 1973 when monthly average oil prices
rose from $4.31 in December 1973 to $10.11 in January 1974.
-
Other
notable moves during the orange cycle: Corn - $1.03
in November, 1971 to $3.97 in September, 1974; Soybeans
- $2.33 in October, 1969 to $12.29 in June, 1973; Wheat
- $1.13 in September, 1968 to $6.92 in February, 1974;
London Metal Exchange Copper - $982.52 in November,
1971 to $3,354.40 in April, 1974; Gold - $34.75 in
January, 1970 to $195.25 in December, 1974.
-
The teal
cycle “set-up” label 1 marks the bottom of the November,
1973 to March, 1975 recession.
-
The teal
cycle thrust from 3 to 4 includes the second oil price
shock. Oil prices advanced from a monthly average of
$13.90 in July, 1977 to $39.50 in July, 1980.
-
Other
notable moves during the teal cycle: Corn - $1.72 in
August, 1977 to $3.69 in November, 1980; Soybeans -
$4.37 in January, 1976 to $10.46 in April, 1977; Wheat
- $2.01 in August, 1977 to $5.07 in November, 1980; London
Metal Exchange Copper - $1,124.11 in August, 1977 to
3,168.96 in February, 1980; Gold - $103.50 in August,
1976 to $850.00 in January, 1980; Silver - $3.82 in
January, 1976 to $48.00 in January, 1980.
-
The
black cycle “set-up” label 3 of October, 2001 marks the
successful retest of the CRB price of label 1 in July, 1999.
The recession bottomed the following month (November 2001).
-
Oil
prices bottomed in November , 2001 at $17.43 and have more
than tripled since.
-
Other
notable moves during the black cycle: Corn - $1.45 in
August, 2000 to $3.15 in April, 2004, 1980; Soybeans
- $3.99 in October, 2001 to $10.41 in March, 2004; Wheat
- $1.94 in August, 2000 to $4.50 in November, 2003; London
Metal Exchange Copper - $1,319 in November, 2001 to
$3,434.50 in March, 2005; Gold - $255.95 in April,
2001 to $454.20.00 in December, 2004.
-
Measuring each cycle in months from the beginning month of
label 1 to the ending month of label 4, we have the
following: Orange cycle – 66 months; Teal Cycle – 68 months;
Black Cycle – 68 months (through March, 2005).
Final
Comments:
-
Three
price patterns of the CRB since 1968 appear to be very
similar in terms of “set-up” and time duration.
-
We are
currently in the third of such patterns.
-
The
bulls will note that our Orange Cycle and Teal Cycle were
back-to back with a one year pause. A repeat of the pattern
after a pause would take commodity prices substantially
higher.
-
The
bears will suggest that the Black Cycle is almost a carbon
copy of the Teal Cycle and a repeat of the price action in
the 1980s is in store.
