Fool's Gold
Re: Fool's Gold
Larry,
A statement in your article brought back memories of my former stock broker especially:
“…when prices are low — you would think investors who were buying gold at $1,900 should certainly welcome the opportunity to buy at $1,230 — if you liked it at $1,900, you should love it at $1,230!
He would always use that line whenever his recommendations tanked! Buy more! There is some truth to that but not for me.
Nice article.

Re: Fool's Gold
Excellent article Larry. I believe those last two sentences pretty well summarizes all an individual investor really needs to know about the field of Behavioral Finance.In one of my favorite Seinfeld episodes, George Constanza has an epiphany that all of his instincts have been wrong, and that he would be best served by doing the opposite. It seems that many, if not most, investors would benefit from the same epiphany.

Re: Fool's Gold
Very well written Mr. Swedroe. Thanks for the article. It is sad that so many investors earn less than their underlying investment funds do because of when they get in and out. Your comment about George Costanza had me ROFL.
Never underestimate the power of the force of low cost index funds.

Larry,
I believe Vanguard showed data at the recent Bogleheads' Conference that returns for individuals trail the returns of the funds they invest in. I think nisiprius pointed out that Morningstar also tracks investor returns, which also generally show a deficit.
It's not just gold that people are chasing.

Re: Fool's Gold
Nice article, thank you. I am confused by the large decrease in assets under management which you point out is not due only to the price decline but actual reduction of the # of shares. This, in itself does not show (I don't think) anything about buying and selling behavior or does it? Shares are created and retired by some mechanism in units by large buyers and sellers, no?

Re: Fool's Gold
The statement while cute does not actually make sense. If I bought gold at $1400 i might be very pleased when it is at 1900 but I am not necessarily "buying" at that price. I might be the seller. The buyers at $1900 have already lost their shirts. Those who bought on the way down have already committed the funds. they own "under water" gold. Unless buyers have other sources of funds those buyers cant buy at 1230. What market clearing does is find that level at which remaining buyers will buy the product. If you believe that gold functions like the stock market (i don't) an index buyer buys at whatever price the market gives you. The idea that investments have some other value than what an efficient market gives you is one of the great lures to the sucker born every minute.Higman wrote:Larry,

Re: Fool's Gold
Actually, this throws into sharp focus the ambiguity of what it means to "rebalance."
Suppose, hypothetically, an investor who holds Total Stock, VTSMX, buys the gold ETF, GLD in 2007, to the extent of 10% of his portfolio. Say, $10,000 GLD, $90,000 Total Stock.
Time marches on. It is now March 2009, he now holds $14,847 in GLD and $49,110 in VTSMX. He is now 23% GLD. Of course he ought to rebalance, but let's say he doesn't.
Time marches on. It is now today. He now holds $18,300 in GLD and $137,700 in VTSMX. He is now 11.7% in GLD. He decides to rebalance.
What should he rebalance TO?
Should he buy GLD and rebalance to 23% GLD?
Should he sell GLD and rebalance to 10% GLD?
Well, of course, you will say, he should have been rebalancing frequently. But if he hasn't been, talking about "rebalancing" now is sort of meaningless, isn't it? There's no operational definition of what it would mean to rebalance "now."
And there's another problem. Since I am not a gold investor it is hard for me to put myself into the gold investor's mindset, but the opinion that has been frequently expressed in this forum is that gold is a kind of insurance policy against inflation. You put a small amount of your portfolio into gold, and don't worry too much about it, confident that if inflation suddenly occurs, gold will deliver a powerful spike at exactly the right time to offset the effect of inflation in the rest of your portfolio. IF that is the theory, then presumably you should not buy OR sell gold until the sharp, unexpected inflation occurs... which, so far it hasn't. To rebalance continuously over the last ten or fifteen years would be gradually frittering away most of your insurance policy, and then slowly build just a little of it back.
Annual income twenty pounds, annual expenditure nineteen nineteen and six, result happiness; Annual income twenty pounds, annual expenditure twenty pounds ought and six, result misery.

Re: Fool's Gold
The "ouch" part of the Permanent Portfolio is that gold is down about 30% YTD. We all know that gold was "trashed" in 1981 when the Fed started raising rates to kill double-digit inflation, but that year gold *only* lost 32.9%. So, we're on track for one of the worst years ever for gold returns based on negligible rate increases -- what will happen if rates really head up? I'm glad that I didn't sign up for a ride on the PP train when things were rolling along a short while back.

Fool's GLD
Larry,
Somebody bought half of GLD's assets at a lower price, they just bought in a manner that removed the asset from GLD's assets.
Perhaps it should be called Fool's GLD. The GLD cohort of gold investors is different from the non-GLD cohort. The non-GLD cohort tend to be contrarians, or they are longer term holders of gold (perhaps in the PP) that are rebalancing, or demand for the commodity is up, or...?

Re: Fool's Gold
The message is that you should buy when stuff is low and out of favor. If you believe in owning some gold it is a much better buy now than it was when everyone was chattering about the Permanent Portfolio. But I'd never put 25% of my portfolio into gold, as the PP suggests. Maybe 5% - 10%.Leeraar wrote:Browser wrote:The "ouch" part of the Permanent Portfolio is that gold is down about 30% YTD.

Some of the accumulators might be retail investors maintaining an AA who held gold before GLD existed and continue to buy the old way, for instance those who were in the PP before GLD existed.larryswedroe wrote:tadamsmar

I agree that GLD is a proxy for the typical retail investor behavior, but perhaps it's also a bit of a proxy for new money behavior.

Uh... nisi... you out of all people... of course he should rebalance back to his original target of 10%.

What should he rebalance TO?
Now that's a good point! It applies to any rebalanced portfolio: if one asset class gradually goes to zero, you will drain all other asset classes by rebalancing into it. Got to implement some kind of a circuit breaker (e.g., limit rebalancing out of gold to 1/2 of peak holdings).nisiprius wrote:To rebalance continuously over the last ten or fifteen years would be gradually frittering away most of your insurance policy, and then slowly build just a little of it back.

Re: Fool's Gold
Here is one of the comments by part of the Sage of Omaha on investing on gold:
"Now, for $7 trillion, there are roughly a billion of farm— acres of farmland in the United States. They're valued at about $2 1/2 trillion. It's about half the continental United States, this farmland. You could have all the farmland in the United States, you could have about seven ExxonMobiles, and you could have $1 trillion of walking around money. And if you offered me the choice of looking at some 67-foot cube of gold and looking at it all day, you know, I mean touching it and fondling it occasionally, you know, and then saying, you know, `Do something for me,' and it says, `I don't do anything. I just stand here and look pretty.' And the alternative to that was to have all the farmland of the country, everything, cotton, corn, soybeans, seven ExxonMobiles. Just think of that. Add $1 trillion of walking around money. I, you know, maybe call me crazy but I'll take the farmland and the ExxonMobiles"

Re: Fool's Gold
I would like to offer another perspective on the HBPP, annual returns on the allocation to gold and the overall portfolio performance.
From my perspective, it is comforting to observe that a portfolio heavily allocated to GLD (25%) and LTTs (25%) would only experience a 2.5% decline YTD in this economic climate. Although I am not pleased with this minor loss given the recent performance in equities, I am not dissuaded from staying the course and plan to re-balance when a tolerance band is breached.
It is often mentioned on this forum not to look at investments in isolation and I would request that you broaden this suggestion to include the permanent portfolio as well. The PP returned 1.53% in 2008 (not rebalanced) with equities incurring a loss of 36.97%. The philosophy does not overweight equity, gold, fixed income or cash and will undoubtedly have an asset that performs poorly during any given year. This year it is gold and to a lesser extent fixed income.

Re: Fool's Gold
I did a kind of quick exercise in a spreadsheet. The method I used was to assume the loss of 5% of the current value in each successive period and rebalance after each period, or not. At that rate of exponential decay it takes 89 periods for an initial value of the losing asset to lose 99% on its own.natureexplorer wrote:What will happen to you portfolio if that asset you have allocated 5% to, drops gradually 99% in value, and you you continue to rebalance into it?
Anyone with math skills?
The result is that starting with a 5% asset and not rebalancing one ends up with a portfolio worth 95.05% of original. If one did rebalance at each interval the ending portfolio value is 80.03%. The result is not exact because 89 periods does not produce a reduction to exactly 1%. If one had a 50/50 portfolio the respective numbers would be 50.5% left vs 10.5% left had one rebalanced 89 times on the way down.
The better answer is probably to devise a differential equation to represent continuous rebalancing and solve for the function of time and evaluate when an original investment would have reached 99% loss.

How would the result change if instead of a 99% drop we assume a 100% drop? We could assume a linear or exponential depreciation.

Not that I'm making a prediction about gold in particular. I have no dog in this fight.
That's why there's a risk premium.

That's the argument against reblancing bands and frequent rebalancing. I rebalance once per year, but longer intervals might be as good or better from my reading.natureexplorer wrote:What will happen to you portfolio if that asset you have allocated 5% to, drops gradually 99% in value, and you you continue to rebalance into it?

Re: Fool's Gold
My model is exponential because I don't imagine an asset that actual goes to flat zero in a finite number of periods. Of course, don't think any real asset does that either. A more likely outcome is that an asset declines to some fraction of starting value and stops declining . Anyway, if I just add a bunch of rows to three times 89 periods the original investment has decayed to 5.63862E-06 and the rebalanced total portfolio to about 51% of original. After 999 periods the portfolio ends up at about 8% of original value. It is arithmetically possible to chase a declining asset a long ways down.

The result is that starting with a 5% asset and not rebalancing one ends up with a portfolio worth 95.05% of original. If one did rebalance at each interval the ending portfolio value is 80.03%. The result is not exact because 89 periods does not produce a reduction to exactly 1%. If one had a 50/50 portfolio the respective numbers would be 50.5% left vs 10.5% left had one rebalanced 89 times on the way down.
The better answer is probably to devise a differential equation to represent continuous rebalancing and solve for the function of time and evaluate when an original investment would have reached 99% loss.
How would the result change if instead of a 99% drop we assume a 100% drop? We could assume a linear or exponential depreciation.

Not too bad, considering. But if one follows the guidelines for Browne's portfolio s/he will avoid exactly the kind of rearview mirror mistakes Larry has outlined in his article.Rick Ferri wrote:Yep, those Gold Bugs were Swatted Again today!

Re: Fool's Gold
Since the beginning of 2000, BRK.A has gone from 56,100 to 174,636. Gold has gone from $282.05 to $1202.10. Since BRK doesn't pay a dividend, they both have the same yield of 0%.cfs wrote:Here is one of the comments by part of the Sage of Omaha on investing on gold:
"Now, for $7 trillion, there are roughly a billion of farm— acres of farmland in the United States. They're valued at about $2 1/2 trillion. It's about half the continental United States, this farmland. You could have all the farmland in the United States, you could have about seven ExxonMobiles, and you could have $1 trillion of walking around money. And if you offered me the choice of looking at some 67-foot cube of gold and looking at it all day, you know, I mean touching it and fondling it occasionally, you know, and then saying, you know, `Do something for me,' and it says, `I don't do anything. I just stand here and look pretty.' And the alternative to that was to have all the farmland of the country, everything, cotton, corn, soybeans, seven ExxonMobiles. Just think of that. Add $1 trillion of walking around money. I, you know, maybe call me crazy but I'll take the farmland and the ExxonMobiles"

Thanks for reading and have a Merry Christmas
So BRK.A has gone up 211% in the last 13 years, whereas gold has gone up 326%.
You go with Buffett; I'll stick with the metal that doesn't do anything but sit there and look pretty.
(And I'm not cherry-picking dates. A comparison of the past 10 years is also very favorable to gold.)

In theory, theory and practice are identical. In practice, they often differ.

I think there are plenty of assets/investments that have declined to a value very close to zero, zero, or even negative (Source: This time is different.).
Re: Fool's Gold
You are right about that. What I am thinking is that real cases of assets that become worthless don't involve a continuous decay at a rate slow enough to actually rebalance into it. More often arrival at value zero occurs with bankruptcy, devaluation, or some other catastrophic event that one would not follow down to zero. The example in this thread is gold, and that would be a case where it is not imaginable that the asset would continue to erode to a thousandth, to a millionth, to a billionth of value while we chase it down.natureexplorer wrote:

"some ... catastrophic event that one would not follow down to zero". How do you decide when to stop re-balancing into that asset? And it doesn't seem like bankruptcy is even that catastrophic of an event these days.
