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:

'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.'

Applying this definition to our asset in some examples:
  • Looking at the total return, or increase in value of 10.9% 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 (107.1%)
  • During the last 3 years, the total return, or increase in value is -5.5%, which is smaller, thus worse than the value of 38.2% from the benchmark.

CAGR:

'The compound annual growth rate isn't a true return rate, but rather a representational figure. It is essentially a number that describes the rate at which an investment would have grown if it had grown the same rate every year and the profits were reinvested at the end of each year. In reality, this sort of performance is unlikely. However, CAGR can be used to smooth returns so that they may be more easily understood when compared to alternative investments.'

Applying this definition to our asset in some examples:
  • The compounded annual growth rate (CAGR) over 5 years of Vanguard Inflation Protected Securities Fund is 2.1%, which is smaller, thus worse compared to the benchmark SPY (15.7%) in the same period.
  • During the last 3 years, the annual return (CAGR) is -1.9%, which is lower, thus worse than the value of 11.4% from the benchmark.

Volatility:

'Volatility is a statistical measure of the dispersion of returns for a given security or market index. Volatility can either be measured by using the standard deviation or variance between returns from that same security or market index. Commonly, the higher the volatility, the riskier the security. In the securities markets, volatility is often associated with big swings in either direction. For example, when the stock market rises and falls more than one percent over a sustained period of time, it is called a 'volatile' market.'

Using this definition on our asset we see for example:
  • The 30 days standard deviation over 5 years of Vanguard Inflation Protected Securities Fund is 6.6%, which is lower, thus better compared to the benchmark SPY (20.9%) in the same period.
  • Compared with SPY (17.5%) in the period of the last 3 years, the 30 days standard deviation of 6.9% is lower, thus better.

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.'

Which means for our asset as example:
  • Looking at the downside deviation of 4.5% 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 (14.9%)
  • Looking at downside deviation in of 4.9% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (12.2%).

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (0.63) in the period of the last 5 years, the risk / return profile (Sharpe) of -0.06 of Vanguard Inflation Protected Securities Fund is smaller, thus worse.
  • Looking at Sharpe Ratio in of -0.63 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.51).

Sortino:

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Using this definition on our asset we see for example:
  • Looking at the downside risk / excess return profile of -0.09 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 (0.88)
  • Looking at downside risk / excess return profile in of -0.9 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.73).

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.'

Using this definition on our asset we see for example:
  • Looking at the Downside risk index of 7.34 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 (9.32 )
  • Compared with SPY (10 ) in the period of the last 3 years, the Downside risk index of 9.4 is lower, 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.'

Which means for our asset as example:
  • Looking at the maximum reduction from previous high of -14.6 days in the last 5 years of Vanguard Inflation Protected Securities Fund, we see it is relatively greater, thus better in comparison to the benchmark SPY (-33.7 days)
  • During the last 3 years, the maximum DrawDown is -14.5 days, which is greater, thus better than the value of -24.5 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'

Using this definition on our asset we see for example:
  • Looking at the maximum days under water of 768 days in the last 5 years of Vanguard Inflation Protected Securities Fund, we see it is relatively greater, thus worse in comparison to the benchmark SPY (488 days)
  • Looking at maximum time in days below previous high water mark in of 687 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (488 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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (123 days) in the period of the last 5 years, the average days below previous high of 260 days of Vanguard Inflation Protected Securities Fund is higher, thus worse.
  • Looking at average days below previous high in of 317 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (178 days).
