Here is a differently-saved version of the Excel spreadsheet (Old Excel style). For those of you having problems opening the spreadsheet in OpenOffice, does this version fix it? https://www.dropbox.com/s/awrb77zcyjuwdw6/Backtest-Portfolio-returns-rev14b.xls?dl=0 And if so, are there any features tha...

I posted the updated spreadsheet.

Here's the forum post:

Dear all, However, I am looking for the same kind of Excel, but with MONTHLY returns instead of yearly. I would like to do more in deep research (monthly drawdowns, correlations, etc) and I need monthly returns for the main asset classes. Marcos. I modified it once for monthly returns in order to c...

Paul - Thanks for the info. Btw did you get the monthly data from M* principia pro or somewhere else?

Thanks CI. I don't mind including the quarterly data but it's just too much work to capture the data for all the funds. Even if I venture out on this path, I won't be able to get the quarterly data for the funds back to 1972 or 1985 for that matter. That's what I figured, I didn't find it easily my...

PRPFX is a good solution for a modest portfolio. Once you get to a more significant one, you'd probably just want to open a brokerage account and buy shares of VTI, TLT, IAU, and SHY. Then for added complexity, instead of TLT, just go out and place an order for the most recent 30-year bonds. And ins...

I liked this scientific explanation of why gold is money from NPR:

Paul Douglas Boyer

I had thought the stock (TSM) volatility (Std. Dev) was a bit higher than you indicate Paul, closer to 18 I had in mind. Yes, due to the data I was using, these are "real" returns, inflation-adjusted. Probably not as meaningful statistically. It is true that nominal standard deviation of TSM was 18...

Paul Douglas Boyer

Well, since 1985 the data doesn't look so good for Harry Browne with respect to real returns. This is silly. You cannot compare portfolios on returns alone! The only way to compare portfolios is to determine if they adequately compensated you for your risk. More risk should equal more return if the...

Here is my interview with Rick Ferri on his views of gold, the Permanent Portfolio and his own investment philosophy: Thanks for doing the interview with Rick.

IIRC the stated historical maximum drawdown for the PP has been in the 4-5% range. Is the 4-5% figure calculated on "annual" basis while your 13.5% reflects a "monthly" basis. Is this reason for the difference? Bob YES! That is a key point I've been making recently about Max Drawdown. We need high ...

Updated with Real returns for PP and S&P 500

The 24.2% "real" max drawdown of the PP occurred in Feb, 1982.

The 54.3% max drawdown for S&P 500 occurred in Mar, 2009.

I'm going to hand that one off (to you), if that's ok! This chart summarizes the returns vs risk of the two portfolios.

I've put together this chart that clearly shows the Total Real Return (dividends reinvested and returns adjusted for reported inflation) of the S&P 500 vs the Permanent Portfolio from January 1, 1970 through September 2010.

There's also a cost to owning gold. If you own bullion or coins, you need a safe place to store it, a way to insurance it, and there's a cost to trade it (not including 28% tax on profits). If you own a gold bullion ETF, you're losing 0.4% per year in fees on top of the taxes (there is a 0.25% fund...

Actually, a well diversified equity portfolio using global index funds and REITs performed about 5% over the past decade, bonds performed about 6%, and a 50% stock and 50% bond portfolio performed 6.5% annualized. The extra 1% kicker came from annual rebalancing. So, it wasn't a 'lost decade' for d...

I believe that when speaking about "gold", it can be a worthwhile exercise to substitute the word "money" instead and see if the argument still makes sense as a reason not to own it.

Do you have any idea why the max draw-down is so much higher for the 100% TIPS case?

Simulated TIPS show a -2.5% and -4% gain in 1972 and 1973 while Gold showed gains of 49% and 71% those years.

Use caution and invest at your own risk.

You've admitted that Emerging Markets did their poorest during what was perhaps the greatest 6-year stretch of prosperity, ever.

Honestly, I'm not sure there's enough data (compared with the S&P or Total Stock Market) to see how VBR (VISVX) and VBO (VEIEX) would actually do during a time of real prosperity.

If these assumptions are all true, then it always makes sense to go all-in today.

Gold's price is not about GOLD, it's about the DOLLAR.
