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 increase in value of 8.1% in the last 5 years of iShares TIPS Bond ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (112.4%)
  • During the last 3 years, the total return, or increase in value is 1.6%, which is lower, thus worse than the value of 41.6% 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.'

Which means for our asset as example:
  • Looking at the compounded annual growth rate (CAGR) of 1.6% in the last 5 years of iShares TIPS Bond ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (16.3%)
  • During the last 3 years, the annual performance (CAGR) is 0.5%, which is lower, thus worse than the value of 12.4% from the benchmark.

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.'

Using this definition on our asset we see for example:
  • Looking at the 30 days standard deviation of 6.3% in the last 5 years of iShares TIPS Bond ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (17.9%)
  • During the last 3 years, the volatility is 6.9%, which is lower, thus better than the value of 18.6% 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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (12.5%) in the period of the last 5 years, the downside volatility of 4.4% of iShares TIPS Bond ETF is lower, thus better.
  • Looking at downside risk in of 4.8% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (12.7%).

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 -0.15, which is lower, thus worse compared to the benchmark SPY (0.77) in the same period.
  • Compared with SPY (0.53) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of -0.29 is lower, thus worse.

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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (1.11) in the period of the last 5 years, the ratio of annual return and downside deviation of -0.21 of iShares TIPS Bond ETF is lower, thus worse.
  • During the last 3 years, the downside risk / excess return profile is -0.41, which is lower, thus worse than the value of 0.77 from the benchmark.

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:
  • Compared with the benchmark SPY (8.47 ) in the period of the last 5 years, the Ulcer Index of 7.6 of iShares TIPS Bond ETF is smaller, thus better.
  • Compared with SPY (5.78 ) in the period of the last 3 years, the Ulcer Index of 4.9 is smaller, thus better.

MaxDD:

'A maximum drawdown is the maximum loss from a peak to a trough of a portfolio, before a new peak is attained. Maximum Drawdown is an indicator of downside risk over a specified time period. It can be used both as a stand-alone measure or as an input into other metrics such as 'Return over Maximum Drawdown' and the Calmar Ratio. Maximum Drawdown is expressed in percentage terms.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (-24.5 days) in the period of the last 5 years, the maximum drop from peak to valley of -14.5 days of iShares TIPS Bond ETF is higher, thus better.
  • Compared with SPY (-18.8 days) in the period of the last 3 years, the maximum reduction from previous high of -9.5 days is larger, thus better.

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:
  • Compared with the benchmark SPY (488 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 871 days of iShares TIPS Bond ETF is greater, thus worse.
  • Compared with SPY (199 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 529 days is larger, thus worse.

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.'

Using this definition on our asset we see for example:
  • Looking at the average days under water of 329 days in the last 5 years of iShares TIPS Bond ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (119 days)
  • Looking at average days under water in of 200 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (46 days).
