'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 (62.7%) in the period of the last 5 years, the total return, or performance of 139.1% of Invesco WilderHill Clean Energy ETF is larger, thus better.
- Looking at total return in of 91.1% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (34.7%).

'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 annual return (CAGR) of 19.1% in the last 5 years of Invesco WilderHill Clean Energy ETF, we see it is relatively higher, thus better in comparison to the benchmark SPY (10.2%)
- Looking at annual return (CAGR) in of 24.1% in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (10.5%).

'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:- The volatility over 5 years of Invesco WilderHill Clean Energy ETF is 41.2%, which is larger, thus worse compared to the benchmark SPY (20.9%) in the same period.
- Looking at volatility in of 50.3% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (24.1%).

'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.'

Which means for our asset as example:- The downside deviation over 5 years of Invesco WilderHill Clean Energy ETF is 28.7%, which is higher, thus worse compared to the benchmark SPY (15.3%) in the same period.
- Compared with SPY (17.6%) in the period of the last 3 years, the downside risk of 34.9% is greater, thus worse.

'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:- The Sharpe Ratio over 5 years of Invesco WilderHill Clean Energy ETF is 0.4, which is greater, thus better compared to the benchmark SPY (0.37) in the same period.
- During the last 3 years, the ratio of return and volatility (Sharpe) is 0.43, which is larger, thus better than the value of 0.33 from the benchmark.

'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:- The excess return divided by the downside deviation over 5 years of Invesco WilderHill Clean Energy ETF is 0.58, which is larger, thus better compared to the benchmark SPY (0.51) in the same period.
- Looking at ratio of annual return and downside deviation in of 0.62 in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (0.45).

'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.'

Using this definition on our asset we see for example:- The Ulcer Ratio over 5 years of Invesco WilderHill Clean Energy ETF is 29 , which is larger, thus worse compared to the benchmark SPY (7.71 ) in the same period.
- Looking at Ulcer Index in of 37 in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (9.08 ).

'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:- The maximum DrawDown over 5 years of Invesco WilderHill Clean Energy ETF is -68.4 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 -68.4 days is lower, thus worse.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (189 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 416 days of Invesco WilderHill Clean Energy ETF is higher, thus worse.
- Looking at maximum days under water in of 416 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (189 days).

'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.'

Applying this definition to our asset in some examples:- The average days below previous high over 5 years of Invesco WilderHill Clean Energy ETF is 103 days, which is larger, thus worse compared to the benchmark SPY (46 days) in the same period.
- Compared with SPY (45 days) in the period of the last 3 years, the average days under water of 140 days is higher, thus worse.
