Vanguard Inflation Protected Securities Fund (VIPSX)

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.'

• The total return, or performance over 5 years of Vanguard Inflation Protected Securities Fund is 16.9%, which is smaller, thus worse compared to the benchmark SPY (154.3%) in the same period.
• Compared with SPY (32.9%) in the period of the last 3 years, the total return of -3.1% is lower, thus worse.

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 (20.6%) in the period of the last 5 years, the annual return (CAGR) of 3.2% of Vanguard Inflation Protected Securities Fund is smaller, thus worse.
• Compared with SPY (10%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of -1.1% 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.'

• The 30 days standard deviation over 5 years of Vanguard Inflation Protected Securities Fund is 6.3%, which is lower, thus better compared to the benchmark SPY (18.4%) in the same period.
• Looking at 30 days standard deviation in of 6.7% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (17%).

DownVol:

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

• Compared with the benchmark SPY (12.4%) in the period of the last 5 years, the downside deviation of 4.2% of Vanguard Inflation Protected Securities Fund is smaller, thus better.
• Compared with SPY (12%) in the period of the last 3 years, the downside risk of 4.7% is smaller, thus better.

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.'

• Compared with the benchmark SPY (0.99) in the period of the last 5 years, the risk / return profile (Sharpe) of 0.11 of Vanguard Inflation Protected Securities Fund is smaller, thus worse.
• Looking at ratio of return and volatility (Sharpe) in of -0.53 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.44).

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.'

• Looking at the excess return divided by the downside deviation of 0.16 in the last 5 years of Vanguard Inflation Protected Securities Fund, we see it is relatively lower, thus worse in comparison to the benchmark SPY (1.46)
• Looking at excess return divided by the downside deviation in of -0.76 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.62).

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 Ulcer Index of 7.5 in the last 5 years of Vanguard Inflation Protected Securities Fund, we see it is relatively smaller, thus better in comparison to the benchmark SPY (8.29 )
• Compared with SPY (8.63 ) in the period of the last 3 years, the Ulcer Index of 8.05 is smaller, thus better.

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 (-24.5 days) in the period of the last 5 years, the maximum reduction from previous high of -14.6 days of Vanguard Inflation Protected Securities Fund is larger, thus better.
• Looking at maximum drop from peak to valley in of -13 days in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (-22.1 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'

• The maximum time in days below previous high water mark over 5 years of Vanguard Inflation Protected Securities Fund is 841 days, which is higher, thus worse compared to the benchmark SPY (488 days) in the same period.
• Looking at maximum days under water in of 752 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (325 days).

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 under water of 308 days in the last 5 years of Vanguard Inflation Protected Securities Fund, we see it is relatively larger, thus worse in comparison to the benchmark SPY (119 days)
• Looking at average time in days below previous high water mark in of 377 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (89 days).
