Description

The investment seeks to track the investment results (before fees and expenses) of the Nasdaq OMX Global Water IndexSM (the underlying index). The fund generally will invest at least 90% of its total assets in the securities that comprise the underlying index, as well as ADRs and GDRs that are based on the securities in the underlying index. The underlying index may be comprised of common stocks, ordinary shares, depositary receipts, depositary shares, Dutch certificates, shares of beneficial interest, stapled securities and tracking stocks and also may include companies in emerging market countries. It is non-diversified.

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.'

Using this definition on our asset we see for example:
  • The total return, or increase in value over 5 years of Invesco Global Water ETF is 31.6%, which is lower, thus worse compared to the benchmark SPY (62.7%) in the same period.
  • Compared with SPY (34.7%) in the period of the last 3 years, the total return, or increase in value of 15.3% is lower, thus worse.

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.'

Using this definition on our asset we see for example:
  • Looking at the compounded annual growth rate (CAGR) of 5.7% in the last 5 years of Invesco Global Water ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (10.2%)
  • During the last 3 years, the annual return (CAGR) is 4.9%, which is smaller, thus worse than the value of 10.5% 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:
  • Looking at the 30 days standard deviation of 20.3% in the last 5 years of Invesco Global Water ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (20.9%)
  • Compared with SPY (24.1%) in the period of the last 3 years, the volatility of 23.4% 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 (15.3%) in the period of the last 5 years, the downside deviation of 14.7% of Invesco Global Water ETF is lower, thus better.
  • Compared with SPY (17.6%) in the period of the last 3 years, the downside volatility of 17% is smaller, 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.'

Applying this definition to our asset in some examples:
  • The ratio of return and volatility (Sharpe) over 5 years of Invesco Global Water ETF is 0.16, which is lower, thus worse compared to the benchmark SPY (0.37) in the same period.
  • During the last 3 years, the risk / return profile (Sharpe) is 0.1, which is smaller, thus worse than the value of 0.33 from the benchmark.

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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (0.51) in the period of the last 5 years, the excess return divided by the downside deviation of 0.22 of Invesco Global Water ETF is lower, thus worse.
  • Compared with SPY (0.45) in the period of the last 3 years, the ratio of annual return and downside deviation of 0.14 is smaller, thus worse.

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.'

Using this definition on our asset we see for example:
  • The Ulcer Ratio over 5 years of Invesco Global Water ETF is 10 , which is larger, thus worse compared to the benchmark SPY (7.71 ) in the same period.
  • Compared with SPY (9.08 ) in the period of the last 3 years, the Downside risk index of 13 is higher, thus worse.

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.'

Which means for our asset as example:
  • Looking at the maximum reduction from previous high of -35.8 days in the last 5 years of Invesco Global Water ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (-33.7 days)
  • Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum drop from peak to valley of -35.8 days is lower, thus worse.

MaxDuration:

'The Maximum 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. It is the length of time the account was in the Max Drawdown. A Max Drawdown measures a retrenchment from when an equity curve reaches a new high. It’s the maximum an account lost during that retrenchment. This method is applied because a valley can’t be measured until a new high occurs. Once the new high is reached, the percentage change from the old high to the bottom of the largest trough is recorded.'

Applying this definition to our asset in some examples:
  • Looking at the maximum days below previous high of 285 days in the last 5 years of Invesco Global Water ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (189 days)
  • Compared with SPY (189 days) in the period of the last 3 years, the maximum days below previous high of 192 days is greater, 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.'

Applying this definition to our asset in some examples:
  • Looking at the average time in days below previous high water mark of 70 days in the last 5 years of Invesco Global Water ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (46 days)
  • Compared with SPY (45 days) in the period of the last 3 years, the average days under water of 52 days is larger, thus worse.
