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.'

Which means for our asset as example:
  • The total return over 5 years of Vanguard Extended Duration Treasury ETF is 54.5%, which is greater, thus better compared to the benchmark SPY (46.1%) in the same period.
  • Looking at total return, or performance in of 65.3% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (23.5%).

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (7.9%) in the period of the last 5 years, the annual return (CAGR) of 9.1% of Vanguard Extended Duration Treasury ETF is greater, thus better.
  • During the last 3 years, the annual return (CAGR) is 18.3%, which is larger, thus better than the value of 7.3% from the benchmark.

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:
  • The volatility over 5 years of Vanguard Extended Duration Treasury ETF is 18.4%, which is larger, thus worse compared to the benchmark SPY (18.3%) in the same period.
  • During the last 3 years, the historical 30 days volatility is 18.1%, which is lower, thus better than the value of 20.8% 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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (13.4%) in the period of the last 5 years, the downside deviation of 12.7% of Vanguard Extended Duration Treasury ETF is lower, thus better.
  • Compared with SPY (15.4%) in the period of the last 3 years, the downside risk of 11.9% is lower, 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:
  • The Sharpe Ratio over 5 years of Vanguard Extended Duration Treasury ETF is 0.36, which is greater, thus better compared to the benchmark SPY (0.29) in the same period.
  • During the last 3 years, the ratio of return and volatility (Sharpe) is 0.87, which is larger, thus better than the value of 0.23 from the benchmark.

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:
  • Compared with the benchmark SPY (0.4) in the period of the last 5 years, the ratio of annual return and downside deviation of 0.52 of Vanguard Extended Duration Treasury ETF is larger, thus better.
  • Looking at ratio of annual return and downside deviation in of 1.33 in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (0.31).

Ulcer:

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

Using this definition on our asset we see for example:
  • The Downside risk index over 5 years of Vanguard Extended Duration Treasury ETF is 13 , which is higher, thus worse compared to the benchmark SPY (5.27 ) in the same period.
  • Compared with SPY (6.08 ) in the period of the last 3 years, the Ulcer Ratio of 6.31 is higher, thus worse.

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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum DrawDown of -24.2 days of Vanguard Extended Duration Treasury ETF is greater, thus better.
  • Looking at maximum reduction from previous high in of -18.5 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) in days.'

Applying this definition to our asset in some examples:
  • Looking at the maximum time in days below previous high water mark of 769 days in the last 5 years of Vanguard Extended Duration Treasury ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (187 days)
  • Compared with SPY (139 days) in the period of the last 3 years, the maximum days below previous high of 318 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.'

Using this definition on our asset we see for example:
  • Looking at the average days below previous high of 270 days in the last 5 years of Vanguard Extended Duration Treasury ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (42 days)
  • During the last 3 years, the average days under water is 89 days, which is greater, thus worse than the value of 36 days from the benchmark.
