It's always good to question data!
Bugs are a part of the business, and I'm happy to hear that whatever glitch you previously ran across has been fixed. Thanks for pointing it out.

Re: Modified Golden Butterfly Portfolio
I also compared long-term performance of "Gold" and "Precious metals" on PV and the chart for the latter looked pretty volatile. Looks like "PM" tracks miners and "gold" is gold. I'm glad we figured this out.sophie wrote:By noticing that the PP since 1987 showed up with a 5% CAGR, which didn't seem correct, so I looked at the components individually (yes I checked I had the right #s in the right places) and gold wasn't behaving like it should. It was a strange result - can't reproduce it now but there was no bump in 2008-2010 for example.
Now I plug in the PP and get an 8.29% CAGR since 1987, which looks correct, and "gold" now looks ok.
Something weird happened. Anyway sounds like "gold" is correct, but maybe watch for this to happen again.
Re: Modified Golden Butterfly Portfolio
Some minor adjustments to the mGB portfolio for 2018 and beyond:
- International stocks are now 25% of the equity allocation (due to elevated U.S. stock valuations versus the rest of the world).
- Long-term bonds are shorter in duration (due to historically low spread between 10-year and 30-year U.S. Treasury yields).
- 20% Large-Cap Blend or Total U.S. Stock Market
- 10% Small-Cap Value
- 10% International Stock Market (Ex-U.S.)
- 10% Long-Term U.S. Treasury (20+ Years)
- 10% Intermediate-Term U.S. Treasury (7-10 Years)
- 20% Gold
- 20% Cash or Short-Term U.S. Treasury
Re: Modified Golden Butterfly Portfolio
Now that it's 2018, there are some fresh adjustments to the asset allocation of the modified portfolio:
- Emerging market (EM) stocks are now 100% of the equity allocation (due to the negative outlook for U.S. and EAFE real returns until 2025).
- Intermediate-term bonds have entirely replaced long-term bonds (due to the historically low spread in U.S. Treasury yields and the negative outlook for interest rates).
- 40% Emerging Market (EM) stocks
- 20% Intermediate-Term U.S. Treasury (7-10 Years)
- 20% Gold
- 20% Cash or Short-Term U.S. Treasury
Re: Modified Golden Butterfly Portfolio
Changing 50% of the portfolio in 1 months time is a big change! Just keep in mind that with that type of turnover all backtests of a static AA are pretty much pointless. I'd argue it's less of a Golden Butterfly and more of a Rudiger portfolio newsletter.
(Not that there's anything wrong with that, and I'm rooting for your personal success.)

Re: Modified Golden Butterfly Portfolio
Point taken! This portfolio is currently in its "testing" phase, which is why the stock and bond allocations have shifted quite a bit in the first few months. Hopefully, it won't change so much in the coming years.Tyler wrote:Changing 50% of the portfolio in 1 months time is a big change!

While this portfolio is heavily inspired by the quintessential Permanent Portfolio and the Golden Butterfly, it's actually more of a tactical approach to asset allocation than a pure "lazy" portfolio. The weights will change as the case is made for big bets on specific asset classes, usually based on a 10-year real return outlook.
Re: Modified Golden Butterfly Portfolio
Rudiger, I agree with the EM call.
Re: Modified Golden Butterfly Portfolio
I just listened to podcast proposing a Golden Butterfly-like portfolio for Indian residents:
This seems to me to be a good framework for non-US investors: split the equity allocation between US and local, and use local bonds.
He suggests a 5x20% allocation, like the GB. According to him the CAGR in rupees was 13% over 30 years, with yearly rebalancing, giving a 31x increase. Lost 7% in 2008. Equal weights were as good or better than other weightings. For debt, he proposes a fund which buys Indian PSU (public sector undertaking) bonds, which essentially medium or long term.Ashish Shanker, head of investments at Motilal Oswal Private Wealth Management, made an argument for an equal-weight allocation to five asset classes — cash or liquid investments, debt, gold, Indian equity and U.S. equity.

Re: Modified Golden Butterfly Portfolio
Thanks Tarentola,
Seems quite a reasonable approach. Modelled it over on Portfolio Charts for Japan and Australia and it had a very low Ulcer Index.
Nice find

I think it's quite good, but he substitutes Total Bond Market funds for the Treasuries (both short and long) which skews the results. He also isn't aware of why SCV was chosen to offset TSM and so just focuses kind of myopically on SCV tanking during the first 6 months of 2020 without understanding its longer-term utility.
It seems to me his proposed alternative allocations could maybe be called "GB-inspired" but they're replacements for not just tweaks of the original. I would see going 25% TSM, 15% SCV and likewise reducing the LTT's to 15% and upping the STT/Cash to 25% as hedges against realities in the stock and bond markets that are arguably long-term trends at this point (i.e. growth trouncing value due to the FAANG stocks and LTT's being rather nitrogylcerin like in their volatility due to rates being at unprecedented lows). But that's about as far as I personally would feel comfortable monkeying around while still considering it a GB iteration.
Interested as always to hear other views. And thanks for sharing such interesting things Hal!
Re: Modified Golden Butterfly Portfolio
Ah, this is what I do! I live in the Netherlands and have split the equity allocation between US and EMU stocks. And with German bonds (the best we have in Europe I think).
I wish I could backtest it with my actual ETFs and bonds, but as far as I know, there is no site that supports EU ETFs and bonds. Of course, the awesome PortfolioCharts.com can confirm the characterisitcs of this allocation.
Re: Modified Golden Butterfly Portfolio
Looking for suggestions please. I have a Euro PP which contains Euro Large Cap shares (Sanofi, Renault, VInci, Luis Vuitton etc). At the moment the PP is not far off 4x25%, being 29/20/25/26% stocks bonds gold cash.
For simplification, I am closing a small account elsewhere, and would like to use the funds there to transform my PP into a Golden Butterfly. This would result in proportions of 16 % new, 24% Euro shares, 17% bonds, 21% gold, 22% cash. By chance, this comes to 40% shares, perfect for a GB.
For more simplification, I am moving towards ETFs rather than individual shares.
I would like to take this opportunity to diversify. My question is: what ETF to buy for this 16% section of the portfolio? My preferences are more or less in this order:
- A World ETF, which would be about 60% US
- Small Cap US
- Large Cap US
- Small Cap Europe
- Emerging Markets
What do you think?

Re: Modified Golden Butterfly Portfolio
Thanks Senecaaa. In what relative proportions do you hold the Euro and US ETFs? I am inclined to 50% US and 50% Euro, but that is arbitrary.
Re: Modified Golden Butterfly Portfolio
I just found an three-part article by Siamond on the Bogleheads blog on world stock investing for non-US investors:
https://www.bogleheads.org/blog/2020/03 ... ld-part-3/
The article concludes:
https://www.bogleheads.org/blog/2020/03 ... ld-part-3/
The article concludes:
Of the World index, the Eurozone is about 10% and the US is 65%, so the 80-20 split above would result in 52% US and 28% Eurozone, with 20% rest of world. That fits with the 50% US mentioned above.World 80%, Domestic Tilt 20%
Let’s cut to the chase a little bit. After playing with historical numbers for a while, the author hypothesized that splitting stocks 80% global world and 20% domestic would have displayed fairly good properties in the past 50 years (1970-2019), a sweet spot of sorts. It would certainly have helped a local investor in countries with the worst track record (e.g. Italy, Spain, Japan) to mitigate various types of risk.
