Vanguard Short-Term Bond Index Fund Investor Shares (VBISX)

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.'

• Compared with the benchmark SPY (94.2%) in the period of the last 5 years, the total return, or increase in value of 5.7% of Vanguard Short-Term Bond Index Fund Investor Shares is smaller, thus worse.
• Looking at total return, or performance in of 3.2% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (34.4%).

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.'

• Compared with the benchmark SPY (14.2%) in the period of the last 5 years, the annual performance (CAGR) of 1.1% of Vanguard Short-Term Bond Index Fund Investor Shares is lower, thus worse.
• Looking at annual return (CAGR) in of 1.1% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (10.4%).

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.'

• The 30 days standard deviation over 5 years of Vanguard Short-Term Bond Index Fund Investor Shares is 2.8%, which is smaller, thus better compared to the benchmark SPY (21%) in the same period.
• Compared with SPY (17.5%) in the period of the last 3 years, the 30 days standard deviation of 3.4% is smaller, thus better.

DownVol:

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

• The downside deviation over 5 years of Vanguard Short-Term Bond Index Fund Investor Shares is 1.9%, which is lower, thus better compared to the benchmark SPY (15%) in the same period.
• During the last 3 years, the downside risk is 2.3%, which is lower, thus better than the value of 12.3% from the benchmark.

Sharpe:

'The Sharpe ratio was developed by Nobel laureate William F. Sharpe, and is used to help investors understand the return of an investment compared to its risk. The ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. Subtracting the risk-free rate from the mean return allows an investor to better isolate the profits associated with risk-taking activities. One intuition of this calculation is that a portfolio engaging in 'zero risk' investments, such as the purchase of U.S. Treasury bills (for which the expected return is the risk-free rate), has a Sharpe ratio of exactly zero. Generally, the greater the value of the Sharpe ratio, the more attractive the risk-adjusted return.'

• Looking at the ratio of return and volatility (Sharpe) of -0.5 in the last 5 years of Vanguard Short-Term Bond Index Fund Investor Shares, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.56)
• During the last 3 years, the ratio of return and volatility (Sharpe) is -0.43, which is lower, thus worse than the value of 0.45 from the benchmark.

Sortino:

'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.'

• The ratio of annual return and downside deviation over 5 years of Vanguard Short-Term Bond Index Fund Investor Shares is -0.74, which is smaller, thus worse compared to the benchmark SPY (0.78) in the same period.
• During the last 3 years, the downside risk / excess return profile is -0.64, which is lower, thus worse than the value of 0.64 from the benchmark.

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.'

• Looking at the Downside risk index of 3.82 in the last 5 years of Vanguard Short-Term Bond Index Fund Investor Shares, we see it is relatively lower, thus better in comparison to the benchmark SPY (9.33 )
• Looking at Downside risk index in of 3.18 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (8.87 ).

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.'

• Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum drop from peak to valley of -9 days of Vanguard Short-Term Bond Index Fund Investor Shares is larger, thus better.
• During the last 3 years, the maximum drop from peak to valley is -6.9 days, which is greater, thus better than the value of -22.4 days from the benchmark.

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.'

• The maximum days under water over 5 years of Vanguard Short-Term Bond Index Fund Investor Shares is 753 days, which is higher, thus worse compared to the benchmark SPY (488 days) in the same period.
• During the last 3 years, the maximum days under water is 512 days, which is greater, thus worse than the value of 375 days from the benchmark.

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.'

• Looking at the average time in days below previous high water mark of 254 days in the last 5 years of Vanguard Short-Term Bond Index Fund Investor Shares, we see it is relatively greater, thus worse in comparison to the benchmark SPY (122 days)
• Compared with SPY (113 days) in the period of the last 3 years, the average time in days below previous high water mark of 192 days is greater, thus worse.
