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 (129.1%) in the period of the last 5 years, the total return, or performance of 103% of Invesco Global Water ETF is smaller, thus worse.
• During the last 3 years, the total return, or increase in value is 75.6%, which is greater, thus better than the value of 71.3% 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.'

• Looking at the annual return (CAGR) of 15.2% in the last 5 years of Invesco Global Water ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (18.1%)
• Compared with SPY (19.7%) in the period of the last 3 years, the annual performance (CAGR) of 20.7% is higher, 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.'

• The historical 30 days volatility over 5 years of Invesco Global Water ETF is 18.5%, which is lower, thus better compared to the benchmark SPY (18.7%) in the same period.
• Looking at historical 30 days volatility in of 21.8% in the period of the last 3 years, we see it is relatively smaller, 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 deviation 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.
• Compared with SPY (16.3%) in the period of the last 3 years, the downside deviation of 15.6% is lower, 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.'

• Compared with the benchmark SPY (0.83) in the period of the last 5 years, the risk / return profile (Sharpe) of 0.69 of Invesco Global Water ETF is smaller, thus worse.
• Looking at risk / return profile (Sharpe) in of 0.83 in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (0.76).

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.'

• Compared with the benchmark SPY (1.15) in the period of the last 5 years, the excess return divided by the downside deviation of 0.96 of Invesco Global Water ETF is lower, thus worse.
• During the last 3 years, the ratio of annual return and downside deviation is 1.16, which is higher, thus better than the value of 1.05 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.'

• The Ulcer Index over 5 years of Invesco Global Water ETF is 6.22 , which is larger, thus worse compared to the benchmark SPY (5.59 ) in the same period.
• Looking at Downside risk index in of 6.79 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (6.38 ).

MaxDD:

'Maximum drawdown is defined as the peak-to-trough decline of an investment during a specific period. It is usually quoted as a percentage of the peak value. The maximum drawdown can be calculated based on absolute returns, in order to identify strategies that suffer less during market downturns, such as low-volatility strategies. However, the maximum drawdown can also be calculated based on returns relative to a benchmark index, for identifying strategies that show steady outperformance over time.'

• Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum DrawDown of -35.8 days of Invesco Global Water ETF is smaller, thus worse.
• Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum DrawDown of -35.8 days is lower, 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). 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'

• The maximum time in days below previous high water mark over 5 years of Invesco Global Water ETF is 285 days, which is larger, thus worse compared to the benchmark SPY (139 days) in the same period.
• Compared with SPY (119 days) in the period of the last 3 years, the maximum days under water of 136 days is larger, thus worse.

AveDuration:

'The Drawdown Duration is the length of any peak to peak period, or the time between new equity highs. 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.'

• The average days below previous high over 5 years of Invesco Global Water ETF is 57 days, which is greater, thus worse compared to the benchmark SPY (32 days) in the same period.
• Compared with SPY (25 days) in the period of the last 3 years, the average time in days below previous high water mark of 27 days is higher, thus worse.
