Description

The classic permanent portfolio was created by Harry Browne. The idea was that a portfolio should be diversified enough to get you through a wide variety of economic and market environments and simple enough that even a child could do it. Originally it consisted of the following allocations:

  • 25% in U.S. stocks
  • 25% in long-term bonds
  • 25% in gold
  • 25% in cash

The Logical Invest permanent portfolio is somewhat more sophisticated, rebalances monthly and is not always split evenly across the three main assets. It can adapt to market conditions by putting more weight on gold or treasuries and less on equity depending on market conditions.

Methodology & Assets
  • US Market (SPY: S&P 500 SPDRs)
  • Long Duration Treasuries (TLT: iShares 20+ Year Treasury Bond)
  • Gold (GLD: Gold Shares SPDR)

Statistics (YTD)

What do these metrics mean? [Read More] [Hide]

TotalReturn:

'Total return is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investment’s overall performance.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (143%) in the period of the last 5 years, the total return of 69.3% of Enhanced Permanent Portfolio Strategy is smaller, thus worse.
  • Looking at total return, or performance in of 26.2% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (39%).

CAGR:

'Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from various data sets of common domain such as revenue growth of companies in the same industry.'

Using this definition on our asset we see for example:
  • Looking at the annual performance (CAGR) of 11.1% in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (19.5%)
  • During the last 3 years, the annual performance (CAGR) is 8.1%, which is lower, thus worse than the value of 11.7% from the benchmark.

Volatility:

'Volatility is a rate at which the price of a security increases or decreases for a given set of returns. Volatility is measured by calculating the standard deviation of the annualized returns over a given period of time. It shows the range to which the price of a security may increase or decrease. Volatility measures the risk of a security. It is used in option pricing formula to gauge the fluctuations in the returns of the underlying assets. Volatility indicates the pricing behavior of the security and helps estimate the fluctuations that may happen in a short period of time.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (19.6%) in the period of the last 5 years, the historical 30 days volatility of 9.4% of Enhanced Permanent Portfolio Strategy is smaller, thus better.
  • During the last 3 years, the volatility is 9%, which is lower, thus better than the value of 17.1% from the benchmark.

DownVol:

'Downside risk is the financial risk associated with losses. That is, it is the risk of the actual return being below the expected return, or the uncertainty about the magnitude of that difference. Risk measures typically quantify the downside risk, whereas the standard deviation (an example of a deviation risk measure) measures both the upside and downside risk. Specifically, downside risk in our definition is the semi-deviation, that is the standard deviation of all negative returns.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (13.5%) in the period of the last 5 years, the downside volatility of 6.5% of Enhanced Permanent Portfolio Strategy is lower, thus better.
  • Compared with SPY (12%) in the period of the last 3 years, the downside risk of 6.1% is lower, thus better.

Sharpe:

'The Sharpe ratio (also known as the Sharpe index, the Sharpe measure, and the reward-to-variability ratio) is a way to examine the performance of an investment by adjusting for its risk. The ratio measures the excess return (or risk premium) per unit of deviation in an investment asset or a trading strategy, typically referred to as risk, named after William F. Sharpe.'

Using this definition on our asset we see for example:
  • The Sharpe Ratio over 5 years of Enhanced Permanent Portfolio Strategy is 0.92, which is higher, thus better compared to the benchmark SPY (0.87) in the same period.
  • Looking at ratio of return and volatility (Sharpe) in of 0.62 in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (0.54).

Sortino:

'The Sortino ratio improves upon the Sharpe ratio by isolating downside volatility from total volatility by dividing excess return by the downside deviation. The Sortino ratio is a variation of the Sharpe ratio that differentiates harmful volatility from total overall volatility by using the asset's standard deviation of negative asset returns, called downside deviation. The Sortino ratio takes the asset's return and subtracts the risk-free rate, and then divides that amount by the asset's downside deviation. The ratio was named after Frank A. Sortino.'

Applying this definition to our asset in some examples:
  • The downside risk / excess return profile over 5 years of Enhanced Permanent Portfolio Strategy is 1.33, which is larger, thus better compared to the benchmark SPY (1.26) in the same period.
  • Compared with SPY (0.77) in the period of the last 3 years, the ratio of annual return and downside deviation of 0.91 is greater, thus better.

Ulcer:

'The ulcer index is a stock market risk measure or technical analysis indicator devised by Peter Martin in 1987, and published by him and Byron McCann in their 1989 book The Investors Guide to Fidelity Funds. It's designed as a measure of volatility, but only volatility in the downward direction, i.e. the amount of drawdown or retracement occurring over a period. Other volatility measures like standard deviation treat up and down movement equally, but a trader doesn't mind upward movement, it's the downside that causes stress and stomach ulcers that the index's name suggests.'

Using this definition on our asset we see for example:
  • The Ulcer Ratio over 5 years of Enhanced Permanent Portfolio Strategy is 4.51 , which is lower, thus better compared to the benchmark SPY (8.32 ) in the same period.
  • Looking at Ulcer Index in of 4.65 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (8.6 ).

MaxDD:

'A maximum drawdown is the maximum loss from a peak to a trough of a portfolio, before a new peak is attained. Maximum Drawdown is an indicator of downside risk over a specified time period. It can be used both as a stand-alone measure or as an input into other metrics such as 'Return over Maximum Drawdown' and the Calmar Ratio. Maximum Drawdown is expressed in percentage terms.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (-24.5 days) in the period of the last 5 years, the maximum DrawDown of -14.9 days of Enhanced Permanent Portfolio Strategy is larger, thus better.
  • Looking at maximum reduction from previous high in of -13.5 days in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (-22.1 days).

MaxDuration:

'The Drawdown Duration is the length of any peak to peak period, or the time between new equity highs. The Max Drawdown Duration is the worst (the maximum/longest) amount of time an investment has seen between peaks (equity highs) in days.'

Which means for our asset as example:
  • The maximum time in days below previous high water mark over 5 years of Enhanced Permanent Portfolio Strategy is 564 days, which is greater, thus worse compared to the benchmark SPY (488 days) in the same period.
  • Compared with SPY (325 days) in the period of the last 3 years, the maximum days below previous high of 430 days is larger, thus worse.

AveDuration:

'The Drawdown Duration is the length of any peak to peak period, or the time between new equity highs. The Avg Drawdown Duration is the average amount of time an investment has seen between peaks (equity highs), or in other terms the average of time under water of all drawdowns. So in contrast to the Maximum duration it does not measure only one drawdown event but calculates the average of all.'

Applying this definition to our asset in some examples:
  • Looking at the average time in days below previous high water mark of 151 days in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively larger, thus worse in comparison to the benchmark SPY (118 days)
  • Compared with SPY (90 days) in the period of the last 3 years, the average time in days below previous high water mark of 140 days is larger, thus worse.
