Description

The investment seeks to track the investment results of Bloomberg Barclays U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) which composed of inflation-protected U.S. Treasury bonds. The fund generally invests at least 90% of its assets in the bonds of the underlying index and at least 95% of its assets in U.S. government bonds. It may invest up to 10% of its assets in U.S. government bonds not included in the underlying index, but which BFA believes will help the fund track the underlying index. It also may invest up to 5% of its assets in repurchase agreements collateralized by U.S. government obligations and in cash and cash equivalents.

Statistics (YTD)

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

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.'

Using this definition on our asset we see for example:
  • Looking at the total return, or performance of 21.9% in the last 5 years of iShares TIPS Bond ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (110.8%)
  • During the last 3 years, the total return is 18.1%, which is lower, thus worse than the value of 50.8% 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.'

Using this definition on our asset we see for example:
  • Looking at the annual return (CAGR) of 4% in the last 5 years of iShares TIPS Bond ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (16.1%)
  • During the last 3 years, the annual return (CAGR) is 5.7%, which is lower, thus worse than the value of 14.7% 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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (18.7%) in the period of the last 5 years, the historical 30 days volatility of 5.2% of iShares TIPS Bond ETF is lower, thus better.
  • Compared with SPY (22.7%) in the period of the last 3 years, the volatility of 5.9% is lower, thus better.

DownVol:

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

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (13.6%) in the period of the last 5 years, the downside volatility of 3.6% of iShares TIPS Bond ETF is smaller, thus better.
  • During the last 3 years, the downside risk is 4%, which is lower, thus better than the value of 16.5% 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.'

Which means for our asset as example:
  • The ratio of return and volatility (Sharpe) over 5 years of iShares TIPS Bond ETF is 0.3, which is smaller, thus worse compared to the benchmark SPY (0.73) in the same period.
  • Looking at Sharpe Ratio in of 0.54 in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (0.54).

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.'

Applying this definition to our asset in some examples:
  • Looking at the downside risk / excess return profile of 0.43 in the last 5 years of iShares TIPS Bond ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (1)
  • During the last 3 years, the excess return divided by the downside deviation is 0.8, which is higher, thus better than the value of 0.74 from the benchmark.

Ulcer:

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

Which means for our asset as example:
  • Compared with the benchmark SPY (5.58 ) in the period of the last 5 years, the Ulcer Ratio of 1.49 of iShares TIPS Bond ETF is lower, thus better.
  • Looking at Ulcer Index in of 1.39 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (6.91 ).

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.'

Using this definition on our asset we see for example:
  • The maximum reduction from previous high over 5 years of iShares TIPS Bond ETF is -11.2 days, which is greater, thus better compared to the benchmark SPY (-33.7 days) in the same period.
  • During the last 3 years, the maximum DrawDown is -11.2 days, which is greater, 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). 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'

Applying this definition to our asset in some examples:
  • The maximum days below previous high over 5 years of iShares TIPS Bond ETF is 293 days, which is larger, thus worse compared to the benchmark SPY (139 days) in the same period.
  • During the last 3 years, the maximum time in days below previous high water mark is 170 days, which is greater, thus worse than the value of 139 days from the benchmark.

AveDuration:

'The Average Drawdown Duration is an extension of the Maximum Drawdown. However, this metric does not explain the drawdown in dollars or percentages, rather in days, weeks, or months. 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:
  • The average days below previous high over 5 years of iShares TIPS Bond ETF is 77 days, which is higher, thus worse compared to the benchmark SPY (33 days) in the same period.
  • Looking at average days below previous high in of 37 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (36 days).
