'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (106.8%) in the period of the last 5 years, the total return, or performance of 71.2% of Invesco S&P 500 Low Volatility ETF is lower, thus worse.
- Compared with SPY (71.9%) in the period of the last 3 years, the total return, or performance of 41.2% is lower, thus worse.

'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.'

Applying this definition to our asset in some examples:- Looking at the compounded annual growth rate (CAGR) of 11.4% in the last 5 years of Invesco S&P 500 Low Volatility ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (15.7%)
- Looking at annual return (CAGR) in of 12.2% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (19.8%).

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (18.9%) in the period of the last 5 years, the historical 30 days volatility of 17.8% of Invesco S&P 500 Low Volatility ETF is lower, thus better.
- Compared with SPY (21.9%) in the period of the last 3 years, the historical 30 days volatility of 21.4% is smaller, thus better.

'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.'

Using this definition on our asset we see for example:- The downside risk over 5 years of Invesco S&P 500 Low Volatility ETF is 13%, which is lower, thus better compared to the benchmark SPY (13.8%) in the same period.
- Compared with SPY (15.9%) in the period of the last 3 years, the downside deviation of 15.5% is lower, thus better.

'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 S&P 500 Low Volatility ETF is 0.5, which is smaller, thus worse compared to the benchmark SPY (0.69) in the same period.
- Looking at risk / return profile (Sharpe) in of 0.45 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.79).

'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.'

Which means for our asset as example:- The excess return divided by the downside deviation over 5 years of Invesco S&P 500 Low Volatility ETF is 0.68, which is lower, thus worse compared to the benchmark SPY (0.95) in the same period.
- Compared with SPY (1.09) in the period of the last 3 years, the excess return divided by the downside deviation of 0.62 is smaller, thus worse.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (5.61 ) in the period of the last 5 years, the Ulcer Ratio of 7.1 of Invesco S&P 500 Low Volatility ETF is greater, thus worse.
- Looking at Ulcer Index in of 8.85 in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (6.08 ).

'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.'

Which means for our asset as example:- The maximum reduction from previous high over 5 years of Invesco S&P 500 Low Volatility ETF is -36.3 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 -36.3 days is smaller, 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:- Looking at the maximum days below previous high of 296 days in the last 5 years of Invesco S&P 500 Low Volatility ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (139 days)
- Compared with SPY (119 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 296 days is greater, thus worse.

'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:- The average days below previous high over 5 years of Invesco S&P 500 Low Volatility ETF is 56 days, which is higher, thus worse compared to the benchmark SPY (32 days) in the same period.
- During the last 3 years, the average days below previous high is 75 days, which is larger, thus worse than the value of 22 days from the benchmark.
