Re: In the Shadow of 1937
I’m willing to concede that even the specific figures I cite above could overstate the sustainable price outperformance of stocks vis-à-vis commodities somewhat. The reason is that the time frame begins in what was a period of relatively low valuation of stocks (early forties) and ends in a period of relatively high valuation of stocks (now). But the degree of low/high valuation can only explain at most, say, a two-three-four factor of price appreciation. This based on accounting for such things as dividend yields, book values, and the total value of the equity markets relative to GDP (whether on a US or global basis). This compares to an overall increase in the nominal price of stocks of 132.8 times versus 4.27 times for commodities. Thus even viewing the data in the light harshest to stocks, we’d still have stock price appreciation of 33.2 times for stocks versus 4.27 times for commodities. So while we could quibble about the degree of long term historical price outperformance of stocks, the fact of its existence is beyond question.
The price of stocks, as I have shown before, tracks overall GDP remarkably closely over long periods of time. It ought to, since stocks represent productive capital. The price of commodities, on the other hand, over time represent a shrinking portion of GDP. It likewise ought to, because the advancement of technology means that fewer hours of labor need be devoted to their production. Decades ago, a it took a quarter to half to population to produce our food supply, while it now takes a small fraction of that. The productive effort thus freed up now goes into the production of things that are not commodities, like electronics, entertainment, movies, television, Internet. The total fraction of productive effort devoted to commodities has been in decline for virtually all of recorded history, while equity capital tracks it proportionately.
So the price underperformance of commodities per se is not only a historical fact, but reasonable in terms of economic rationality.
As for the historical fact, no one need take my word for it. The data I’ve charted above is widely publicly available from respected sources such as Dow Jones, Morgan Stanley Capital, Standard and Poor’s, and the Commodity Research Bureau, and any one wishing to do so can corroborate it themselves if they wish.
As you know, I am happy to concede the existence of your "reverse hedonics", since I have complained myself about the diminution of quality in, for example, agricultural commodities due to the introduction of cheaper gene-spliced substitutes for the "real thing" of yesteryear, as well as numerous other substitutions of questionable quality "equivalents". But that does nothing to detract from the indisputable apples-to-apples nature of the data I cite. You could just as easily argue that the stock of a Monsanto or Cargill is a cheaper substitute for the "real thing". And even more to the point, the fact of such substitution is already embedded in the commodity price indices. The question of the quality of the commodities themselves is completely independent of the actual, factual, historical record of commodity prices. The commodity price indices are constructed to represent the experience of an average investor owning commodities, just as the stock price indices are constructed to represent the experience of an average investor owning stocks. If we are to truly conduct an apples-to-apples comparison, we can hardly compare real stocks with hypothetical commodities.
This last point you raise speaks not to the relative price performance of stocks versus commodities, but to the question of inflation and the relative value of the currency to stocks and commodities respectively. It is an extraneous third variable which we eliminate by using the same monetary unit in which to price stocks and commodities, thus factoring out the common denominator. No matter how you slice it, the price of stocks as a class relative to commodities as a class, over the sixty-four year period cited, has risen by a factor of 132.8/4.27 - over thirty. No matter what currency you use and regardless of the degree of inflation it has undergone, the ratio stock:commodity remains the same.
We can even control for reverse hedonics if we like, by looking only at commodities whose essential makeup is the same over time. Such as gold. One can convert any desired index of stock prices from inflating currency units to gold and one will still see a sustainable, long-term increase in price. This is because of the same phenomenon of advancing technology and productivity as cited above in connection with commodity prices in general. For actual historical data, one can refer to the well-known Ibbotson Associates. Just using the same time frame as cited above, the price of gold was $34 per ounce in 1942, and the S&P 500 was $9. Thus the price of gold has increased by 18-fold since 1942, while the price of the S&P has increased 158-fold. Eliminating the dollar unit, the price of the S&P 500 has increased by 158/18 - or over eight times - even in terms of gold. Similar results occur with any representative equity and commodity group over sufficient time, as here, to encompass one or more full secular cyles.
Reviewing the record developed thus far, it is clear that we have abundant hard data showing conclusively that stock prices have far outperformed commodity prices over very long periods of time. We have no data at all showing otherwise.
