Gold, S&P 500: Deciphering Investment Seesaws and Insights Into Market Dynamics

 | Mar 26, 2024 05:19AM ET

We consider gold bullion and the S&P 500 Index (SPX) to be effectively at opposite ends of an investment seesaw, with the SPX doing better when confidence in money, central banking and government is rising and gold doing better when confidence in money, central banking and government is falling. As discussed in a few TSI commentaries and blog posts over the past two years (for example, HERE), our investment seesaw concept was part of the inspiration for the Synchronous Equity and Gold Price Model (SEGPM) created by Dietmar Knoll.

In general terms, the SEGPM uses historical data to define a quantitative relationship between the SPX, the US$ gold price and the US money supply. More specifically, it is based on the fact that adding the SPX to 1.5 times the US$ gold price (and applying a scaling factor) has, over the long term, resulted in a number that tracks the US money supply. Consequently, it indicates the extent to which the combination of the US stock market and gold is currently under/over-valued compared to the money supply and can provide clues regarding likely future price levels for gold and the SPX. For example, a forecast of likely future levels for the SPX and the money supply would project a likely future level for the US$ gold price.

The following monthly chart shows our version of the SEGPM. On this chart, the red line is US True Money Supply (TMS) and the blue line is the Gold-SPX Model (the sum of the S&P 500 Index and 1.5 times the US$ gold price, multiplied by a scaling factor).
