Statistics of Invesco Global Water ETF (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:
  • Compared with the benchmark SPY (67.7%) in the period of the last 5 years, the total return of 40.8% of Invesco Global Water ETF is smaller, thus worse.
  • Compared with SPY (46.7%) in the period of the last 3 years, the total return of 49.4% is larger, thus better.

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 Invesco Global Water ETF is 7.1%, which is lower, thus worse compared to the benchmark SPY (10.9%) in the same period.
  • Compared with SPY (13.7%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 14.4% is greater, thus better.

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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (13.5%) in the period of the last 5 years, the historical 30 days volatility of 15% of Invesco Global Water ETF is higher, thus worse.
  • During the last 3 years, the 30 days standard deviation is 13.5%, which is greater, thus worse than the value of 12.8% from the benchmark.

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:
  • The downside volatility over 5 years of Invesco Global Water ETF is 16.1%, which is greater, thus worse compared to the benchmark SPY (14.8%) in the same period.
  • Looking at downside volatility in of 14.7% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (14.6%).

Sharpe:

'The Sharpe ratio is the measure of risk-adjusted return of a financial portfolio. Sharpe ratio is a measure of excess portfolio return over the risk-free rate relative to its standard deviation. Normally, the 90-day Treasury bill rate is taken as the proxy for risk-free rate. A portfolio with a higher Sharpe ratio is considered superior relative to its peers. The measure was named after William F Sharpe, a Nobel laureate and professor of finance, emeritus at Stanford University.'

Using this definition on our asset we see for example:
  • Looking at the Sharpe Ratio of 0.31 in the last 5 years of Invesco Global Water ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.62)
  • Compared with SPY (0.87) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of 0.88 is greater, thus better.

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 ratio of annual return and downside deviation of 0.29 in the last 5 years of Invesco Global Water ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.57)
  • During the last 3 years, the ratio of annual return and downside deviation is 0.81, which is greater, thus better than the value of 0.76 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:
  • The Ulcer Ratio over 5 years of Invesco Global Water ETF is 9.3 , which is higher, thus worse compared to the benchmark SPY (3.99 ) in the same period.
  • Compared with SPY (4.1 ) in the period of the last 3 years, the Ulcer Ratio of 4.52 is greater, thus worse.

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.'

Applying this definition to our asset in some examples:
  • Looking at the maximum reduction from previous high of -26.3 days in the last 5 years of Invesco Global Water ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (-19.3 days)
  • Looking at maximum drop from peak to valley in of -16.9 days in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (-19.3 days).

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.'

Using this definition on our asset we see for example:
  • The maximum days under water over 5 years of Invesco Global Water ETF is 578 days, which is greater, thus worse compared to the benchmark SPY (187 days) in the same period.
  • Compared with SPY (139 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 281 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:
  • Compared with the benchmark SPY (42 days) in the period of the last 5 years, the average days below previous high of 181 days of Invesco Global Water ETF is larger, thus worse.
  • Compared with SPY (36 days) in the period of the last 3 years, the average days below previous high of 72 days is higher, thus worse.
