Description

The investment seeks to track the performance of an index of extended-duration zero-coupon U.S. Treasury securities. The fund employs an indexing investment approach designed to track the performance of the Bloomberg Barclays U.S. Treasury STRIPS 20-30 Year Equal Par Bond Index. This index includes zero-coupon U.S. Treasury securities (Treasury STRIPS), which are backed by the full faith and credit of the U.S. government, with maturities ranging from 20 to 30 years. The fund invests by sampling the index. At least 80% of it's assets will be invested in U.S. Treasury securities held in the index.

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 over 5 years of Vanguard Extended Duration Treasury ETF is 20.5%, which is lower, thus worse compared to the benchmark SPY (121.6%) in the same period.
  • During the last 3 years, the total return, or performance is 41.2%, which is smaller, thus worse than the value of 64.5% from the benchmark.

CAGR:

'The compound annual growth rate (CAGR) is a useful measure of growth over multiple time periods. It can be thought of as the growth rate that gets you from the initial investment value to the ending investment value if you assume that the investment has been compounding over the time period.'

Using this definition on our asset we see for example:
  • Looking at the compounded annual growth rate (CAGR) of 3.8% in the last 5 years of Vanguard Extended Duration Treasury ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (17.3%)
  • Compared with SPY (18.1%) in the period of the last 3 years, the annual performance (CAGR) of 12.2% is lower, thus worse.

Volatility:

'In finance, volatility (symbol σ) is the degree of variation of a trading price series over time as measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). Commonly, the higher the volatility, the riskier the security.'

Using this definition on our asset we see for example:
  • Looking at the volatility of 17.8% in the last 5 years of Vanguard Extended Duration Treasury ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (18.7%)
  • Looking at volatility in of 19.6% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (22.5%).

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.'

Applying this definition to our asset in some examples:
  • The downside volatility over 5 years of Vanguard Extended Duration Treasury ETF is 12.3%, which is lower, thus better compared to the benchmark SPY (13.5%) in the same period.
  • Compared with SPY (16.4%) in the period of the last 3 years, the downside risk of 13% is smaller, thus better.

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 ratio of return and volatility (Sharpe) of 0.07 in the last 5 years of Vanguard Extended Duration Treasury ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.79)
  • Looking at risk / return profile (Sharpe) in of 0.5 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.69).

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.'

Using this definition on our asset we see for example:
  • Looking at the ratio of annual return and downside deviation of 0.11 in the last 5 years of Vanguard Extended Duration Treasury ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (1.09)
  • Looking at ratio of annual return and downside deviation in of 0.74 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.95).

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.'

Which means for our asset as example:
  • The Ulcer Ratio over 5 years of Vanguard Extended Duration Treasury ETF is 14 , which is higher, thus worse compared to the benchmark SPY (5.58 ) in the same period.
  • Looking at Downside risk index in of 11 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (6.83 ).

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 drop from peak to valley over 5 years of Vanguard Extended Duration Treasury ETF is -27.3 days, which is higher, thus better compared to the benchmark SPY (-33.7 days) in the same period.
  • Looking at maximum drop from peak to valley in of -27.3 days in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (-33.7 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'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (139 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 734 days of Vanguard Extended Duration Treasury ETF is larger, thus worse.
  • Compared with SPY (139 days) in the period of the last 3 years, the maximum days below previous high of 352 days is higher, 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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (33 days) in the period of the last 5 years, the average time in days below previous high water mark of 274 days of Vanguard Extended Duration Treasury ETF is larger, thus worse.
  • Compared with SPY (35 days) in the period of the last 3 years, the average days under water of 107 days is higher, thus worse.
