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, when measuring performance, is the actual rate of return of an investment or a pool of investments over a given evaluation period. Total return includes interest, capital gains, dividends and distributions realized over a given period of time. Total return accounts for two categories of return: income including interest paid by fixed-income investments, distributions or dividends and capital appreciation, representing the change in the market price of an asset.'

Which means for our asset as example:
  • Looking at the total return of 76% in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively lower, thus worse in comparison to the benchmark SPY (107.7%)
  • Looking at total return, or increase in value in of 25.4% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (33.8%).

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:
  • Compared with the benchmark SPY (15.8%) in the period of the last 5 years, the annual performance (CAGR) of 12% of Enhanced Permanent Portfolio Strategy is smaller, thus worse.
  • Looking at annual return (CAGR) in of 7.9% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (10.2%).

Volatility:

'Volatility is a statistical measure of the dispersion of returns for a given security or market index. Volatility can either be measured by using the standard deviation or variance between returns from that same security or market index. Commonly, the higher the volatility, the riskier the security. In the securities markets, volatility is often associated with big swings in either direction. For example, when the stock market rises and falls more than one percent over a sustained period of time, it is called a 'volatile' market.'

Which means for our asset as example:
  • The volatility over 5 years of Enhanced Permanent Portfolio Strategy is 9.5%, which is lower, thus better compared to the benchmark SPY (20.9%) in the same period.
  • Compared with SPY (17.5%) in the period of the last 3 years, the historical 30 days volatility of 9% is lower, thus better.

DownVol:

'The downside volatility is similar to the volatility, or standard deviation, but only takes losing/negative periods into account.'

Which means for our asset as example:
  • The downside risk over 5 years of Enhanced Permanent Portfolio Strategy is 6.6%, which is lower, thus better compared to the benchmark SPY (14.9%) in the same period.
  • During the last 3 years, the downside volatility is 6.2%, which is smaller, thus better than the value of 12.2% from the benchmark.

Sharpe:

'The Sharpe ratio is the measure of risk-adjusted return of a financial portfolio. Sharpe ratio is a measure of excess portfolio return over the risk-free rate relative to its standard deviation. Normally, the 90-day Treasury bill rate is taken as the proxy for risk-free rate. A portfolio with a higher Sharpe ratio is considered superior relative to its peers. The measure was named after William F Sharpe, a Nobel laureate and professor of finance, emeritus at Stanford University.'

Applying this definition to our asset in some examples:
  • Looking at the risk / return profile (Sharpe) of 0.99 in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively greater, thus better in comparison to the benchmark SPY (0.63)
  • Compared with SPY (0.44) in the period of the last 3 years, the risk / return profile (Sharpe) of 0.59 is greater, thus better.

Sortino:

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Which means for our asset as example:
  • Compared with the benchmark SPY (0.89) in the period of the last 5 years, the downside risk / excess return profile of 1.43 of Enhanced Permanent Portfolio Strategy is larger, thus better.
  • Compared with SPY (0.63) in the period of the last 3 years, the ratio of annual return and downside deviation of 0.87 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 4.54 , which is smaller, thus better compared to the benchmark SPY (9.32 ) in the same period.
  • Compared with SPY (10 ) in the period of the last 3 years, the Ulcer Ratio of 5.62 is lower, thus better.

MaxDD:

'Maximum drawdown is defined as the peak-to-trough decline of an investment during a specific period. It is usually quoted as a percentage of the peak value. The maximum drawdown can be calculated based on absolute returns, in order to identify strategies that suffer less during market downturns, such as low-volatility strategies. However, the maximum drawdown can also be calculated based on returns relative to a benchmark index, for identifying strategies that show steady outperformance over time.'

Applying this definition to our asset in some examples:
  • The maximum DrawDown over 5 years of Enhanced Permanent Portfolio Strategy is -14.9 days, which is higher, thus better compared to the benchmark SPY (-33.7 days) in the same period.
  • Looking at maximum DrawDown in of -14.9 days in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (-24.5 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:
  • Compared with the benchmark SPY (488 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 564 days of Enhanced Permanent Portfolio Strategy is higher, thus worse.
  • Looking at maximum time in days below previous high water mark in of 436 days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (488 days).

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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (123 days) in the period of the last 5 years, the average time in days below previous high water mark of 153 days of Enhanced Permanent Portfolio Strategy is higher, thus worse.
  • Compared with SPY (178 days) in the period of the last 3 years, the average days under water of 143 days is lower, thus better.
