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

TotalReturn:

'Total return, when measuring performance, is the actual rate of return of an investment or a pool of investments over a given evaluation period. Total return includes interest, capital gains, dividends and distributions realized over a given period of time. Total return accounts for two categories of return: income including interest paid by fixed-income investments, distributions or dividends and capital appreciation, representing the change in the market price of an asset.'

• Compared with the benchmark SPY (115.1%) in the period of the last 5 years, the total return, or increase in value of 4.8% of Vanguard Short-Term Bond Index Fund Investor Shares is lower, thus worse.
• During the last 3 years, the total return is 10%, which is lower, thus worse than the value of 71.1% from the benchmark.

CAGR:

'Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from various data sets of common domain such as revenue growth of companies in the same industry.'

• Looking at the annual return (CAGR) of 0.9% 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 (16.6%)
• During the last 3 years, the compounded annual growth rate (CAGR) is 3.2%, which is lower, thus worse than the value of 19.7% 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.'

• Compared with the benchmark SPY (17.5%) in the period of the last 5 years, the historical 30 days volatility of 2.8% of Vanguard Short-Term Bond Index Fund Investor Shares is smaller, thus better.
• During the last 3 years, the historical 30 days volatility is 3.2%, which is lower, thus better than the value of 17.5% from the benchmark.

DownVol:

'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.'

• Looking at the downside risk of 1.9% 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 (12.1%)
• During the last 3 years, the downside deviation is 2%, which is smaller, thus better than the value of 11.5% 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.'

• The risk / return profile (Sharpe) over 5 years of Vanguard Short-Term Bond Index Fund Investor Shares is -0.55, which is lower, thus worse compared to the benchmark SPY (0.8) in the same period.
• Looking at ratio of return and volatility (Sharpe) in of 0.23 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.98).

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.'

• Looking at the downside risk / excess return profile of -0.82 in the last 5 years of Vanguard Short-Term Bond Index Fund Investor Shares, we see it is relatively lower, thus worse in comparison to the benchmark SPY (1.17)
• Compared with SPY (1.49) in the period of the last 3 years, the downside risk / excess return profile of 0.37 is lower, thus worse.

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.'

• Compared with the benchmark SPY (8.48 ) in the period of the last 5 years, the Ulcer Ratio of 3.65 of Vanguard Short-Term Bond Index Fund Investor Shares is smaller, thus better.
• Looking at Downside risk index in of 1.3 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (5.31 ).

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.'

• The maximum reduction from previous high over 5 years of Vanguard Short-Term Bond Index Fund Investor Shares is -8.7 days, which is higher, thus better compared to the benchmark SPY (-24.5 days) in the same period.
• During the last 3 years, the maximum DrawDown is -4.1 days, which is larger, thus better than the value of -18.8 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). 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'

• The maximum days under water over 5 years of Vanguard Short-Term Bond Index Fund Investor Shares is 751 days, which is higher, thus worse compared to the benchmark SPY (488 days) in the same period.
• Compared with SPY (199 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 161 days is lower, thus better.

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 days below previous high of 250 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 (120 days)
• During the last 3 years, the average time in days below previous high water mark is 49 days, which is higher, thus worse than the value of 47 days from the benchmark.
