@rjb112(1) Since you are familiar with Siegel's book, do you have any reason why a supposedly scholarly undertaking like this fails to identify on its central chart which T-Bill maturity the plot-line reflects? The difference would be small. But I'd have more confidence in his numbers if I knew the methodology employed to reach them.
(2) I think we agree that gold is not an attractive long term investment.
(3) I think we also agree that over shorter periods (such as the referenced 1
5 year time-span) gold does sometimes perform quite well when compared against some other investments.
I'm not sure we disagree on anything of substance here.
hank, I don't know the answer to your question in (1). I strongly suspect the answer to which Treasury Bills were used will be found in Chapter
5, where he says, "In Chapter
5 we examine the details of these return series and see how they are constructed."
I don't have the time nor inclination to read that chapter. I don't own the book, but have it available thru the public library e-book series.
I agree with you when you say "The difference would be small." Since he refers to short term bonds as having the 2.7% annualized real return, he is equating the Treasury Bills he used for the chart to short term bonds. Perhaps he used one year T-bills? I have no idea, and agree with you that it would be much better to have that stated outright. I would also like to see the bonds identified....such as 30-year Treasury bonds, and even the stocks identified. That's where I'm guessing Chapter
5 comes into play.
I agree with your (2) and (3) above........certainly over the past 210 years, gold has been a terrible investment, but also, nobody has lived 210 years to hold it that long and achieve that terrible return. So if you bought gold in January of 2001 and sold it in 2011, you did fabulously. If you bought gold in 1980 at over $800/ounce and sold it in 2000 or 2001 at under $300/ounce, you did terribly.
All these things, including small cap value stocks, large cap growth, value stocks versus growth stocks, foreign stocks vs. US stocks, emerging market stocks, etc etc......are quite time period dependent. Large cap growth did great from 199
5-2000, then did terrible, while small cap value did great starting 2000.........
Actually, I don't think we disagree on anything here.
And I'm not against gold.
Some of my favorite investors have invested in gold, such as Jean Marie Eveillard, the late Peter Bernstein, William (Bill) Bernstein, and others. I think Buffett may have even invested in gold or silver at one time. And John Templeton I'm pretty sure bought silver at one time.
And you don't have to look at gold as something you invest in to hit a home run with respect to total return. Many invest in it as an insurance policy against bad outcomes.
take care
