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:

'The total return on a portfolio of investments takes into account not only the capital appreciation on the portfolio, but also the income received on the portfolio. The income typically consists of interest, dividends, and securities lending fees. This contrasts with the price return, which takes into account only the capital gain on an investment.'

Which means for our asset as example:
  • The total return, or performance over 5 years of Enhanced Permanent Portfolio Strategy is 74.9%, which is lower, thus worse compared to the benchmark SPY (97.2%) in the same period.
  • Looking at total return, or increase in value in of 68.8% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (80.6%).

CAGR:

'The compound annual growth rate isn't a true return rate, but rather a representational figure. It is essentially a number that describes the rate at which an investment would have grown if it had grown the same rate every year and the profits were reinvested at the end of each year. In reality, this sort of performance is unlikely. However, CAGR can be used to smooth returns so that they may be more easily understood when compared to alternative investments.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (14.6%) in the period of the last 5 years, the annual performance (CAGR) of 11.9% of Enhanced Permanent Portfolio Strategy is lower, thus worse.
  • Compared with SPY (21.8%) in the period of the last 3 years, the annual performance (CAGR) of 19.1% is lower, thus worse.

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.'

Which means for our asset as example:
  • Looking at the volatility of 8.9% in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively smaller, thus better in comparison to the benchmark SPY (17.1%)
  • Looking at historical 30 days volatility in of 8.7% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (15.2%).

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%, which is lower, thus better compared to the benchmark SPY (11.8%) in the same period.
  • During the last 3 years, the downside volatility is 5.6%, which is smaller, thus better than the value of 10.2% 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.'

Which means for our asset as example:
  • The ratio of return and volatility (Sharpe) over 5 years of Enhanced Permanent Portfolio Strategy is 1.06, which is larger, thus better compared to the benchmark SPY (0.71) in the same period.
  • During the last 3 years, the risk / return profile (Sharpe) is 1.92, which is greater, thus better than the value of 1.27 from the benchmark.

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.'

Applying this definition to our asset in some examples:
  • The ratio of annual return and downside deviation over 5 years of Enhanced Permanent Portfolio Strategy is 1.57, which is higher, thus better compared to the benchmark SPY (1.03) in the same period.
  • Compared with SPY (1.9) in the period of the last 3 years, the excess return divided by the downside deviation of 2.95 is greater, thus better.

Ulcer:

'The Ulcer Index is a technical indicator that measures downside risk, in terms of both the depth and duration of price declines. The index increases in value as the price moves farther away from a recent high and falls as the price rises to new highs. The indicator is usually calculated over a 14-day period, with the Ulcer Index showing the percentage drawdown a trader can expect from the high over that period. The greater the value of the Ulcer Index, the longer it takes for a stock to get back to the former high.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (8.42 ) in the period of the last 5 years, the Ulcer Index of 4.47 of Enhanced Permanent Portfolio Strategy is smaller, thus better.
  • Compared with SPY (3.51 ) in the period of the last 3 years, the Ulcer Index of 1.69 is lower, thus better.

MaxDD:

'Maximum drawdown measures the loss in any losing period during a fund’s investment record. It is defined as the percent retrenchment from a fund’s peak value to the fund’s valley value. The drawdown is in effect from the time the fund’s retrenchment begins until a new fund high is reached. The maximum drawdown encompasses both the period from the fund’s peak to the fund’s valley (length), and the time from the fund’s valley to a new fund high (recovery). It measures the largest percentage drawdown that has occurred in any fund’s data record.'

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 higher, thus better.
  • Looking at maximum drop from peak to valley in of -5 days in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (-18.8 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). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred. But that isn’t always the case. The Max DD duration is the longest time between peaks, period. So it could be the time when the program also had its biggest peak to valley loss (and usually is, because the program needs a long time to recover from the largest loss), but it doesn’t have to be'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (488 days) in the period of the last 5 years, the maximum days under water of 564 days of Enhanced Permanent Portfolio Strategy is larger, thus worse.
  • Looking at maximum days under water in of 92 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (87 days).

AveDuration:

'The Average Drawdown Duration is an extension of the Maximum Drawdown. However, this metric does not explain the drawdown in dollars or percentages, rather in days, weeks, or months. 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 days below previous high of 151 days in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively greater, thus worse in comparison to the benchmark SPY (120 days)
  • Compared with SPY (21 days) in the period of the last 3 years, the average days below previous high of 20 days is lower, thus better.
