After peaking at 893.85 on July 3rd, the S&P GSCI index has suffered a
deep reversal in recent weeks. Trading this morning took the index down to 744
(as crude oil tested the key $120 level) and it is currently just above the 750
level (short-term support). Below 750 there does not appear to be any obvious
resting place above the 200 day moving average at 689, some 200 points (or 22%)
below its recent all time high.
The question therefore arises as to whether this is simply another bull
market correction that will be followed by a rapid recovery or something more
meaningful. The lower chart, which shows a 21 day Percentage Rate of Change
(ROC), may be helpful on this regard. Note that the current decline is more
severe than any experienced since March 2003 (the start of the Iraq war which
saw the crude oil price briefly collapse). Should support at $120 for crude and
750 for the S&P GSCI Index fail to hold, the ROC would probably end up
challenging its 2003 level, which would be a reasonable indication that the
current sell-off is the start of a more protracted move lower for the commodity
complex. Obviously the investment money at stake in 2008 is many many multiples
of that which was at stake 5 years ago - not only was the index a quarter of the
price in 2003 but also there was very little financial money directly exposed to
the commodity complex back at that time.
