S&P and Gold Seesaw Update

 | Nov 16, 2022 03:15AM ET

Many times over the years we’ve argued that gold and the world’s most important equity index, the S&P 500, are at opposite ends of a virtual investment seesaw. If one is in a long-term bull market then the other must be in a long-term bear market, with the gold/SPX ratio determining where the real bull market lies.

Our ‘investment seesaw’ concept was part of the inspiration for a model, called the Synchronous Equity and Gold Price Model (SEGPM)*, that defines a quantitative relationship between the SPX, the gold price and the US money supply. What is the SEGPM’s current message?

Before we answer the above question, a brief recap is in order.

In general terms and as explained in the above-linked blog post, the SEGPM is based on the concept that there are periods when an increase in the money supply will boost the SPX more than it will boost the gold price and other periods when an increase in the money supply will boost the gold price more than it will boost the SPX, with the general level of trust/confidence in money, the financial system and government determining whether the SPX or gold is the primary beneficiary of monetary inflation. During long periods when trust/confidence is high or trending upward, increases in the money supply will tend to do a lot for the SPX and very little for gold. The opposite is the case during long periods when trust/confidence is low or falling.

More specifically, the SEGPM is based on the concept that adding the SPX to 1.5-times the gold price (and applying a scaling factor) results in a number that tracks the US money supply over the long-term.

The following monthly chart replicates the model using our calculation of US True Money Supply (TMS). The money supply is shown in red and the SEGPM (the sum of the S&P 500 Index and 1.5-times the gold price) is shown in blue.
