Vanguard Short Term Treasury Fund Investor Shares

'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:- Looking at the total return, or performance of % in the last 5 years of Vanguard Short Term Treasury Fund, we see it is relatively lower, thus worse in comparison to the benchmark SPY (68.6%)
- Looking at total return in of % in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (51%).

'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:- The annual return (CAGR) over 5 years of Vanguard Short Term Treasury Fund is %, which is lower, thus worse compared to the benchmark SPY (11%) in the same period.
- Looking at annual performance (CAGR) in of % in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (14.8%).

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (13.5%) in the period of the last 5 years, the 30 days standard deviation of % of Vanguard Short Term Treasury Fund is lower, thus better.
- During the last 3 years, the volatility is %, which is lower, thus better than the value of 12.8% from the benchmark.

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

Using this definition on our asset we see for example:- Compared with the benchmark SPY (14.9%) in the period of the last 5 years, the downside deviation of % of Vanguard Short Term Treasury Fund is smaller, thus better.
- During the last 3 years, the downside deviation is %, which is lower, thus better than the value of 14.7% from the benchmark.

'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.'

Using this definition on our asset we see for example:- Looking at the risk / return profile (Sharpe) of in the last 5 years of Vanguard Short Term Treasury Fund, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.63)
- Compared with SPY (0.96) in the period of the last 3 years, the risk / return profile (Sharpe) of is lower, thus worse.

'The Sortino ratio, a variation of the Sharpe ratio only factors in the downside, or negative volatility, rather than the total volatility used in calculating the Sharpe ratio. The theory behind the Sortino variation is that upside volatility is a plus for the investment, and it, therefore, should not be included in the risk calculation. Therefore, the Sortino ratio takes upside volatility out of the equation and uses only the downside standard deviation in its calculation instead of the total standard deviation that is used in calculating the Sharpe ratio.'

Using this definition on our asset we see for example:- The ratio of annual return and downside deviation over 5 years of Vanguard Short Term Treasury Fund is , which is smaller, thus worse compared to the benchmark SPY (0.57) in the same period.
- Compared with SPY (0.83) in the period of the last 3 years, the downside risk / excess return profile of is lower, thus worse.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (3.99 ) in the period of the last 5 years, the Downside risk index of of Vanguard Short Term Treasury Fund is smaller, thus better.
- Looking at Downside risk index in of in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (4.1 ).

'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.'

Which means for our asset as example:- The maximum drop from peak to valley over 5 years of Vanguard Short Term Treasury Fund is days, which is larger, thus better compared to the benchmark SPY (-19.3 days) in the same period.
- During the last 3 years, the maximum drop from peak to valley is days, which is higher, thus better than the value of -19.3 days from the benchmark.

'The Maximum 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. It is the length of time the account was in the Max Drawdown. A Max Drawdown measures a retrenchment from when an equity curve reaches a new high. It’s the maximum an account lost during that retrenchment. This method is applied because a valley can’t be measured until a new high occurs. Once the new high is reached, the percentage change from the old high to the bottom of the largest trough is recorded.'

Applying this definition to our asset in some examples:- Looking at the maximum days under water of days in the last 5 years of Vanguard Short Term Treasury Fund, we see it is relatively lower, thus better in comparison to the benchmark SPY (187 days)
- Compared with SPY (139 days) in the period of the last 3 years, the maximum time in days below previous high water mark of days is lower, thus better.

'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:- The average days below previous high over 5 years of Vanguard Short Term Treasury Fund is days, which is lower, thus better compared to the benchmark SPY (42 days) in the same period.
- Looking at average days under water in of days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (36 days).
