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.'

• Compared with the benchmark SPY (113.4%) in the period of the last 5 years, the total return of 5.6% of Vanguard Inflation Protected Securities Fund is smaller, thus worse.
• Compared with SPY (69.8%) in the period of the last 3 years, the total return, or increase in value of 4% is lower, thus worse.

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.'

• Compared with the benchmark SPY (16.4%) in the period of the last 5 years, the annual performance (CAGR) of 1.1% of Vanguard Inflation Protected Securities Fund is smaller, thus worse.
• Compared with SPY (19.4%) in the period of the last 3 years, the annual return (CAGR) of 1.3% is smaller, 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.'

• Looking at the 30 days standard deviation of 6% in the last 5 years of Vanguard Inflation Protected Securities Fund, we see it is relatively lower, thus better in comparison to the benchmark SPY (17.6%)
• Compared with SPY (17.5%) in the period of the last 3 years, the 30 days standard deviation of 6.3% is smaller, thus better.

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.'

• Compared with the benchmark SPY (12.1%) in the period of the last 5 years, the downside risk of 4.2% of Vanguard Inflation Protected Securities Fund is lower, thus better.
• During the last 3 years, the downside volatility is 4.4%, which is lower, 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.'

• Compared with the benchmark SPY (0.79) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of -0.23 of Vanguard Inflation Protected Securities Fund is lower, thus worse.
• Looking at risk / return profile (Sharpe) in of -0.19 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.97).

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 -0.33 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 (1.15)
• Looking at excess return divided by the downside deviation in of -0.27 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (1.47).

Ulcer:

'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.'

• Compared with the benchmark SPY (8.48 ) in the period of the last 5 years, the Ulcer Index of 7.58 of Vanguard Inflation Protected Securities Fund is lower, thus better.
• Compared with SPY (5.31 ) in the period of the last 3 years, the Ulcer Index of 5 is lower, thus better.

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.'

• Looking at the maximum DrawDown of -14.5 days in the last 5 years of Vanguard Inflation Protected Securities Fund, we see it is relatively higher, thus better in comparison to the benchmark SPY (-24.5 days)
• During the last 3 years, the maximum reduction from previous high is -9.7 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) in days.'

• The maximum days under water over 5 years of Vanguard Inflation Protected Securities Fund is 911 days, which is larger, thus worse compared to the benchmark SPY (488 days) in the same period.
• During the last 3 years, the maximum days under water is 527 days, which is higher, thus worse than the value of 199 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.'

• The average time in days below previous high water mark over 5 years of Vanguard Inflation Protected Securities Fund is 355 days, which is greater, thus worse compared to the benchmark SPY (120 days) in the same period.
• During the last 3 years, the average days under water is 201 days, which is greater, thus worse than the value of 47 days from the benchmark.
