Invesco Global Water ETF (PIO)

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.'

• Compared with the benchmark SPY (122.1%) in the period of the last 5 years, the total return of 99.8% of Invesco Global Water ETF is lower, thus worse.
• During the last 3 years, the total return, or performance is 68%, which is larger, thus better than the value of 64.6% from the benchmark.

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.'

• The compounded annual growth rate (CAGR) over 5 years of Invesco Global Water ETF is 14.9%, which is smaller, thus worse compared to the benchmark SPY (17.3%) in the same period.
• Compared with SPY (18.1%) in the period of the last 3 years, the annual performance (CAGR) of 18.9% is higher, thus better.

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.'

• Compared with the benchmark SPY (18.7%) in the period of the last 5 years, the 30 days standard deviation of 18.5% of Invesco Global Water ETF is lower, thus better.
• Looking at historical 30 days volatility in of 21.9% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (22.5%).

DownVol:

'Downside risk is the financial risk associated with losses. That is, it is the risk of the actual return being below the expected return, or the uncertainty about the magnitude of that difference. 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.'

• The downside risk over 5 years of Invesco Global Water ETF is 13.3%, which is lower, thus better compared to the benchmark SPY (13.6%) in the same period.
• Looking at downside risk in of 15.6% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (16.4%).

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.'

• The risk / return profile (Sharpe) over 5 years of Invesco Global Water ETF is 0.67, which is lower, thus worse compared to the benchmark SPY (0.79) in the same period.
• During the last 3 years, the risk / return profile (Sharpe) is 0.75, which is higher, thus better than the value of 0.69 from the benchmark.

Sortino:

'The Sortino ratio, a variation of the Sharpe ratio only factors in the downside, or negative volatility, rather than the total volatility used in calculating the Sharpe ratio. The theory behind the Sortino variation is that upside volatility is a plus for the investment, and it, therefore, should not be included in the risk calculation. Therefore, the Sortino ratio takes upside volatility out of the equation and uses only the downside standard deviation in its calculation instead of the total standard deviation that is used in calculating the Sharpe ratio.'

• Looking at the downside risk / excess return profile of 0.93 in the last 5 years of Invesco Global Water ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (1.09)
• During the last 3 years, the excess return divided by the downside deviation is 1.05, which is higher, thus better than the value of 0.95 from the benchmark.

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.'

• Compared with the benchmark SPY (5.58 ) in the period of the last 5 years, the Downside risk index of 6.35 of Invesco Global Water ETF is higher, thus worse.
• During the last 3 years, the Ulcer Index is 7.12 , which is higher, thus worse than the value of 6.83 from the benchmark.

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.'

• The maximum drop from peak to valley over 5 years of Invesco Global Water ETF is -35.8 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
• Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum DrawDown of -35.8 days is smaller, thus worse.

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.'

• Compared with the benchmark SPY (139 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 281 days of Invesco Global Water ETF is larger, thus worse.
• During the last 3 years, the maximum time in days below previous high water mark is 136 days, which is lower, thus better 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.'

• Compared with the benchmark SPY (33 days) in the period of the last 5 years, the average time in days below previous high water mark of 61 days of Invesco Global Water ETF is higher, thus worse.
• Compared with SPY (35 days) in the period of the last 3 years, the average time in days below previous high water mark of 32 days is lower, thus better.
