For those of you who prefer exuberance of the rational variety, may we direct your attention to natural gas, the only commodity to double in price so far in 2000?

While gasoline prices have been turning a few heads of late, at least we have some usual suspects, such as


and the

Environmental Protection Agency

, to blame. Natural gas, however, is produced right here in the U.S. and in Canada, and has long been the great hope for environmentalists. Natural gas: We loved it to death.

As in the case of all romantic tragedies, it wasn't supposed to happen this way, and certainly not at this time of year. Natural gas prices, unsurprisingly, have tended to peak during the middle of winter and to be soft in the late spring and early autumn, the so-called "shoulder" months of energy demand. But we can see below that the natural gas seasonal cycle has been anything but stable over the past quarter-century.

After price deregulation was phased in, prices rose rapidly in the winter and fell in the summer. Once natural gas-futures trading began in 1991, the seasonal peaks and troughs began to narrow as predicted by futures market theory. A second and smaller seasonal peak began to emerge, corresponding to demand from electric utilities. By 1999, this peak was above the annual average.

The current $4.406 price is near the winter record of $4.573 set on Dec. 20, 1996. Moreover, the level of

backwardation, or premium of the first-month futures to the second month, is rather tame. The winter price spikes, particularly those of 1995-96 and 1996-97, were accompanied by surges in backwardation as well.

This move in the intermonth spread reflected, correctly, the sentiment that prices would soon retreat. No such warning sign is embedded in today's forward curve of natural gas futures. Option volatility has risen to 50% from 40% to reflect the greater risk in the market, but nothing in the market's structure is indicating a peak.

Who Wins, Who Loses?

We demonstrated

last week how utilities could defend themselves by vertical integration into natural gas production and active natural gas trading and risk management. How have other large, natural gas-dependent industries, such as petrochemical producers, fared in this higher fuel and feedstock environment, and what are the implications for the future? (Natural gas is used as both a raw material and as a fuel. It is used by petrochemical and fertilizer manufacturers as a raw material -- feedstock -- and this gives these companies a double-whammy on the higher prices.)

Two indices were examined relative to the

S&P 500

: the AMEX Natural Gas Index, or XNG, of natural gas producers and the S&P Chemicals Composite Index. The paths of these two indices, and of natural gas prices themselves, are shown below.

Two features stand out since March 1994, the first date when data were available for all the indices: the extreme underperformance of the XNG until last winter and the sudden collapse of the S&P Chemicals Composite at the same time.

Du Pont

(DD) - Get Report

dominates the 16-member Chemicals Composite Index with a 37.449% weight;

Dow Chemical

(DOW) - Get Report

is a distant second with a 16.643% weight. Du Pont had, by any measure, a horrible first quarter, plunging from a high of $74 on Jan. 7 to a low of $45.0625 on March 13.

Dow Chemical didn't do much better, falling from a high of $141.5 on Jan. 6 to a low of $92 on March 8. These plunges coincided with the

Nasdaq Composite Index's

surge; they were the good old days when the Nasdaq rose while the

Dow Jones Industrial Average

fell on a regular basis.

The chemical industry, like most basic-materials industries, is a sensitive economic barometer. Higher feedstock costs and an economy slowing under the weight of interest-rate increases are quite negative for these stocks. While we may be getting close to the end of the interest-rate increase cycle, the threat to growth of the Old Economy variety is still quite real; no one yet knows whether the


has already gone too far.

The path of the XNG index is slightly more intriguing. This group has been sliding relative to the S&P for six years, and it ignored all previous winter price spikes -- the ones accompanied by high backwardation. As noted above, the present price increase is neither in the winter nor accompanied by strong backwardation. As a result, it may be far more sustainable and far more conducive to long-term earnings increases in the sector.

The catch, and it is a big catch, is how difficult it is for primary-commodity producers and distributors to capture the economic rent of higher prices. Ultimately, price increases lead to slower demand growth and stimulate new sources of supply and/or substitution, and both of these effects get passed up the supply chain to the wellhead.

Companies that are vertically integrated and manage risk well should win; the losers likely will be those that use natural gas as a feedstock.
