HUI Bull Seasonals 4

 | Nov 21, 2011 03:16AM ET

After updating my gold-seasonality research last week, I heard from traders wondering how it affects gold stocks.  Since the price of gold is their primary driver, gold seasonality naturally has a major impact on gold-stock price levels.  This is readily apparent in the seasonality of the HUI, the flagship gold-stock index.  As you’d expect, this sector mirrors and amplifies the seasonal swings in the metal it mines.

Gold’s seasonality is demand-driven.  Throughout much of the calendar year, various income-cycle and cultural factors around the world drive outsized spikes in gold demand.  After discussing these in depth in last week’s essay on gold bull seasonals, there’s no need to rehash them here.  But while gold’s demand varies radically over a calendar year, its mined supply is almost perfectly inelastic.

Gold’s newly-mined supply flows into the markets at an essentially-constant rate.  It generally takes over a decade between finding a new deposit to building an operating mine.  Plenty of time-consuming steps slow this process, from drilling to define the ore body to securing permitting to arranging financing to ordering long-lead-time equipment to scheduling construction.  This process simply can’t be rushed.

And once a gold mine is operational, its ore can only be extracted and processed at a certain rate pre-defined in the pre-construction engineering process.  It doesn’t matter if the gold price rockets an order of magnitude higher tomorrow.  There is generally no way to increase gold production at operating mines that doesn’t necessitate huge capital investments and new construction over a multi-year time span.

Since global gold supply simply can’t be ramped up to meet seasonal demand spikes, the only possible economic outcome is for the gold price to be bid higher.  An essentially-fixed supply is temporarily overwhelmed by surging demand, forcing the capital flowing into gold to compete for this scarce resource.  This dynamic drives gold seasonals, which are then mirrored and amplified by the gold stocks.

The best way to understand gold-stock seasonality is through the lens of this sector’s primary index, now known as the NYSE Arca Gold BUGS Index.  A clever play on the somewhat-disparaging gold-bug label, BUGS stands for Basket of Unhedged Gold Stocks.  The 16 major gold miners now included in this index are collectively responsible for the majority of global gold mining today.  It is better known by its symbol, HUI.  And born in 1996, it has been around for today’s entire secular gold bull.

Naturally for this HUI-seasonality research, I use the same methodology from my gold-seasonality work.  It deviates from conventional seasonal analysis, which often considers 30-year blocks of time.  The problem with such long spans is they encompass secular bulls and bears alike.  Yet prices behave very differently in bulls and bears, as all speculators and investors know.  So if seasonality is to be used as a gold-stock-bull trading tool, it is logical to limit the data fed into it to gold-stock-bull years.

And of course as any bull market marches higher, its prevailing price levels gradually rise.  So far this year, the HUI has averaged 553.  This is 9x higher than its 2001 average of 60!  A 5-point move back then was gargantuan, but the same today is trivial.  So in order to make every year comparable, we have to individually index each year’s HUI action.  This makes all years perfectly comparable in percentage terms.

My indexing methodology is simple.  The first trading day of each calendar year (or month for the second chart) is recast at 100.  Then the rest of that year’s daily HUI action in percentage terms is rendered off that common base.  If the HUI climbs 10% in any year, no matter what its absolute level, this index rises to 110.  If it falls 10%, its index goes to 90.  Averaging all these individual annual indexes together yields this fascinating chart of HUI bull seasonals.
