Description

The investment seeks to provide inflation protection and income consistent with investment in inflation-indexed securities. The fund invests at least 80% of its assets in inflation-indexed bonds issued by the U.S. government, its agencies and instrumentalities, and corporations. It may invest in bonds of any maturity; however, its dollar-weighted average maturity is expected to be in the range of 7 to 20 years. At a minimum, all bonds purchased by the fund will be rated investment-grade or, if unrated, will be considered by the advisor to be investment-grade.

Statistics (YTD)

What do these metrics mean? [Read More] [Hide]

TotalReturn:

'Total return is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investment’s overall performance.'

Using this definition on our asset we see for example:
  • Looking at the total return of 13.4% 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 (63%)
  • Looking at total return in of 3% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (33.5%).

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.'

Which means for our asset as example:
  • The annual performance (CAGR) over 5 years of Vanguard Inflation Protected Securities Fund is 2.6%, which is lower, thus worse compared to the benchmark SPY (10.3%) in the same period.
  • Looking at compounded annual growth rate (CAGR) in of 1% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (10.1%).

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.'

Applying this definition to our asset in some examples:
  • Looking at the 30 days standard deviation of 6.2% 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 (21.6%)
  • During the last 3 years, the historical 30 days volatility is 7.4%, which is lower, thus better than the value of 25.1% 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.'

Using this definition on our asset we see for example:
  • The downside risk over 5 years of Vanguard Inflation Protected Securities Fund is 4.3%, which is smaller, thus better compared to the benchmark SPY (15.6%) in the same period.
  • Compared with SPY (18.1%) in the period of the last 3 years, the downside volatility of 5.3% is lower, 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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (0.36) in the period of the last 5 years, the Sharpe Ratio of 0.01 of Vanguard Inflation Protected Securities Fund is lower, thus worse.
  • Looking at ratio of return and volatility (Sharpe) in of -0.2 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.3).

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.'

Which means for our asset as example:
  • Looking at the excess return divided by the downside deviation of 0.01 in the last 5 years of Vanguard Inflation Protected Securities Fund, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.5)
  • Looking at downside risk / excess return profile in of -0.29 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.42).

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.'

Which means for our asset as example:
  • Looking at the Ulcer Ratio of 4.2 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 (8.88 )
  • Looking at Ulcer Ratio in of 5.33 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (11 ).

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.'

Using this definition on our asset we see for example:
  • Looking at the maximum DrawDown of -14.1 days in the last 5 years of Vanguard Inflation Protected Securities Fund, we see it is relatively larger, thus better in comparison to the benchmark SPY (-33.7 days)
  • During the last 3 years, the maximum DrawDown is -14.1 days, which is higher, thus better than the value of -33.7 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.'

Applying this definition to our asset in some examples:
  • Looking at the maximum days below previous high of 310 days in the last 5 years of Vanguard Inflation Protected Securities Fund, we see it is relatively higher, thus worse in comparison to the benchmark SPY (273 days)
  • During the last 3 years, the maximum days below previous high is 310 days, which is greater, thus worse than the value of 273 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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (57 days) in the period of the last 5 years, the average days below previous high of 69 days of Vanguard Inflation Protected Securities Fund is higher, thus worse.
  • Compared with SPY (73 days) in the period of the last 3 years, the average time in days below previous high water mark of 82 days is larger, thus worse.
