'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 performance over 5 years of Invesco WilderHill Clean Energy ETF is 645.6%, which is greater, thus better compared to the benchmark SPY (125.9%) in the same period.
- Looking at total return, or increase in value in of 433.2% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (44.4%).

'Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from various data sets of common domain such as revenue growth of companies in the same industry.'

Which means for our asset as example:- Compared with the benchmark SPY (17.7%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of 49.5% of Invesco WilderHill Clean Energy ETF is greater, thus better.
- Compared with SPY (13%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 74.6% is greater, thus better.

'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:- The 30 days standard deviation over 5 years of Invesco WilderHill Clean Energy ETF is 31.5%, which is larger, thus worse compared to the benchmark SPY (18.7%) in the same period.
- Looking at historical 30 days volatility in of 37.2% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (22.8%).

'The downside volatility is similar to the volatility, or standard deviation, but only takes losing/negative periods into account.'

Which means for our asset as example:- Compared with the benchmark SPY (13.6%) in the period of the last 5 years, the downside deviation of 21.4% of Invesco WilderHill Clean Energy ETF is higher, thus worse.
- During the last 3 years, the downside volatility is 25.2%, which is greater, thus worse than the value of 16.7% from the benchmark.

'The Sharpe ratio (also known as the Sharpe index, the Sharpe measure, and the reward-to-variability ratio) is a way to examine the performance of an investment by adjusting for its risk. The ratio measures the excess return (or risk premium) per unit of deviation in an investment asset or a trading strategy, typically referred to as risk, named after William F. Sharpe.'

Which means for our asset as example:- The Sharpe Ratio over 5 years of Invesco WilderHill Clean Energy ETF is 1.49, which is higher, thus better compared to the benchmark SPY (0.81) in the same period.
- Looking at risk / return profile (Sharpe) in of 1.94 in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (0.46).

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (1.12) in the period of the last 5 years, the downside risk / excess return profile of 2.2 of Invesco WilderHill Clean Energy ETF is greater, thus better.
- During the last 3 years, the excess return divided by the downside deviation is 2.86, which is greater, thus better than the value of 0.63 from the benchmark.

'The Ulcer Index is a technical indicator that measures downside risk, in terms of both the depth and duration of price declines. The index increases in value as the price moves farther away from a recent high and falls as the price rises to new highs. The indicator is usually calculated over a 14-day period, with the Ulcer Index showing the percentage drawdown a trader can expect from the high over that period. The greater the value of the Ulcer Index, the longer it takes for a stock to get back to the former high.'

Which means for our asset as example:- The Downside risk index over 5 years of Invesco WilderHill Clean Energy ETF is 9.82 , which is greater, thus worse compared to the benchmark SPY (5.59 ) in the same period.
- During the last 3 years, the Downside risk index is 11 , which is larger, thus worse than the value of 7.14 from the benchmark.

'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:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum drop from peak to valley of -48.9 days of Invesco WilderHill Clean Energy ETF is smaller, thus worse.
- During the last 3 years, the maximum drop from peak to valley is -48.9 days, which is smaller, thus worse than the value of -33.7 days from the benchmark.

'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'

Which means for our asset as example:- Compared with the benchmark SPY (139 days) in the period of the last 5 years, the maximum days below previous high of 248 days of Invesco WilderHill Clean Energy ETF is greater, thus worse.
- During the last 3 years, the maximum days under water is 184 days, which is greater, thus worse than the value of 139 days from the benchmark.

'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.'

Which means for our asset as example:- The average days below previous high over 5 years of Invesco WilderHill Clean Energy ETF is 56 days, which is higher, thus worse compared to the benchmark SPY (33 days) in the same period.
- During the last 3 years, the average time in days below previous high water mark is 40 days, which is lower, thus better than the value of 45 days from the benchmark.
