Here's a question many investors have asked in recent weeks, especially given
the current divergence between the gold and copper prices.
Copper has a history of providing leading signals for the price of gold. Most
notably, the copper price double-bottomed between 1999-2001 and refused to
make a lower low during a time when the price of gold make a 20-year low. This
leading signal in copper preceded the major turnaround in the yellow metal
price in 2002 and beyond.
For years I've relied on the proxy of Freeport Copper & Gold (FCX) as
a leading/confirming indicator for the XAU gold/silver mining index. It's true
that the copper producers have historically led the gold mining stocks at pivotal
turning points in short-, intermediate- and even long-term time frames. This
appears to be one area of mining sector research in need of greater attention.
With this question of copper vs. gold leadership in mind, let's take a look
back in recent history in search of a potential connection between the two.
We'll start by looking at a major blue chip copper stock, Southern Copper Corp.
Southern Copper Corporation produces copper, molybdenum, zinc, and silver.
The company, formerly known as Southern Peru Copper Corporation, was founded
in 1952 and is based in Phoenix, Arizona. Southern Copper is a subsidiary of
Americas Mining Corporation. The stock, which trades under the symbol PCU on
the NYSE, has long been a leading indicator of the XAU gold/silver index as
a comparative analysis of both charts will show.
In late 1999 when the Kress 30-year cycle for equities peaked, the gold stock
group as represented by the XAU also suffered from the broad market selling
pressure. The XAU made an interim peak in October 1999 along with PCU. The
XAU was the first to peak out and from there the XAU entered a downward trend,
making a series of lower highs and lowers lows throughout the year 2000. The
XAU finally hit bottom in October 2000 - exactly one year after its peak.
During 1999-2000, PCU made a higher low against the XAU index. While the XAU
broke below its 1999 low, PCU stayed above its low from '99 and made a conspicuously
positive divergence against the XAU. This was the first intermediate-term technical
signal that the gold stocks were due a reversal and it turned out to be prescient.
The XAU embarked on an 18-month rally off its October 2000 low at the 43 level
to its high just below 90 in May 2002.

By the time the XAU made its multi-year high at the 90 level in May 2002,
PCU failed to make a higher high. This was an intermediate-term negative divergence
and it predicted a period of weakness ahead for the gold stocks. Not surprisingly,
the XAU entered a period of underperformance relative to the broad market as
it pulled back from its May '02 high and entered a 14-month trading range between
the 60 and 80 levels.
The XAU finally broke out above 80 in July 2003, but not before another leading
signal from PCU. PCU broke out to a higher high in January 2003 at the same
time the XAU was making a lower high below its May 2002 peak. The breakout
made by PCU in January 2003 was the signal that the major trend for the mining
sector was up, notwithstanding the interim weakness in the XAU index. Within
five months of this leading signal from PCU, the XAU broke out of its interim
trading range and was on its way to higher levels in 2003.

After a vigorous rally in the second half of 2003, the XAU made a double top
between December 2003 and January 2004. This led into a long period of underperformance
versus the S&P as the XAU experienced a rather large trading range in 2004
which stretched from the 80 level to the 110 level. The XAU closed with a loss
for 2004, yet PCU made a higher high in October 2004 which signaled that a
period of strength was just ahead for the gold stocks.
After overcoming a shaky start to the New Year in 2005, the XAU recovered
to make a higher high in 2005. True to form, PCU had led the way higher for
the gold stock group once again.
In May 2006 the XAU encountered resistance and there followed another period
of underperformance as the XAU spent the better part of the period between
May and December '06 in a narrow trading range between the 120 and 150 levels.
While the XAU closed the year 2006 below its high from May of that year, how
did PCU fare? The stock managed to close 2006 on a high note after making a
series of higher highs and higher lows throughout that year. This was yet another
leading indicator that the XAU would eventually succeed in breaking out of
its interim trading range and travel to higher levels.

The anticipated breakout in the XAU didn't occur until July 2007. It was followed
by a whipsaw-type pullback in August '07. At the August 2007 low the call/put
open interest ratio for the CBOE Gold Index reached an extraordinary level
which strongly suggested that insiders were heavily long the gold stocks. This
proved to be an accurate indicator as the XAU roared ahead from the August
low into November of that year to a new all-time high, covering a ground of
nearly 75 points from bottom to top. After a brief but shallow correction in
November-December, the XAU recovered its old high and made a slightly higher
on Jan. 11, 2008.
Up until the November 2007 high in the XAU, the PCU price line was confirming
the bull market in the gold stocks. Since November '07, however, PCU has pulled
back and retraced some of its previous gains and is now at its lowest close
(as of January 11, 2008) since August 2007. PCU has been lagging the XAU for
the past two-and-a-half months. Is this a concern for the gold stocks?

The lag between the upside breakout to new highs in PCU in November 2006 and
the XAU's eventual breakout in the summer of 2007 was obviously a lot longer
than the historical norm. It's possible that the gold stocks will overcompensate
for this long lag by continuing to surge upward in the weeks ahead even if
PCU and the other leading copper stocks continue to underperform. At some point,
though, a continued lag between copper and gold, and the copper and gold mining
stocks, will reach the break point and the yellow metal, along with the PM
stocks, will give way to the negative undercurrent.
Much of the current strength reflected in gold and the leading gold stocks
is due to the fear premium as investors run for cover from the widespread fears
over the economy. Gold has greatly benefited from its safe haven status during
this time of investor uncertainty. When the fear has finally lifted, however,
the fear premium will no longer be in the yellow metal's favor. The "heads
up" signal in such equities as PCU, FCX, IMN:TSX and TCK seem to be warning
of this intermediate-term eventuality.
