'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:- Looking at the total return of -0.1% in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (32.9%)
- During the last 3 years, the total return, or performance is -7.6%, which is smaller, thus worse than the value of 11.6% from the benchmark.

'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.'

Using this definition on our asset we see for example:- The annual return (CAGR) over 5 years of Invesco BuyBack Achievers ETF is 0%, which is smaller, thus worse compared to the benchmark SPY (5.8%) in the same period.
- Compared with SPY (3.7%) in the period of the last 3 years, the annual performance (CAGR) of -2.6% is lower, thus worse.

'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%) in the period of the last 5 years, the volatility of 20% of Invesco BuyBack Achievers ETF is larger, thus worse.
- Compared with SPY (20.3%) in the period of the last 3 years, the historical 30 days volatility of 22.8% is greater, thus worse.

'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.'

Applying this definition to our asset in some examples:- Looking at the downside risk of 14.9% in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (13.4%)
- Compared with SPY (15.3%) in the period of the last 3 years, the downside risk of 17.2% is larger, thus worse.

'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.'

Applying this definition to our asset in some examples:- Looking at the Sharpe Ratio of -0.13 in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.19)
- Looking at Sharpe Ratio in of -0.22 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.06).

'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.'

Using this definition on our asset we see for example:- The excess return divided by the downside deviation over 5 years of Invesco BuyBack Achievers ETF is -0.17, which is smaller, thus worse compared to the benchmark SPY (0.25) in the same period.
- During the last 3 years, the ratio of annual return and downside deviation is -0.3, which is lower, thus worse than the value of 0.08 from the benchmark.

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

Using this definition on our asset we see for example:- Looking at the Ulcer Ratio of 7.43 in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (5.17 )
- Looking at Downside risk index in of 7.72 in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (5.93 ).

'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.'

Applying this definition to our asset in some examples:- Looking at the maximum reduction from previous high of -40.9 days in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (-33.7 days)
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum DrawDown of -40.9 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.'

Applying this definition to our asset in some examples:- Looking at the maximum time in days below previous high water mark of 353 days in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (187 days)
- Looking at maximum days under water in of 305 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (139 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.'

Which means for our asset as example:- The average time in days below previous high water mark over 5 years of Invesco BuyBack Achievers ETF is 103 days, which is higher, thus worse compared to the benchmark SPY (42 days) in the same period.
- During the last 3 years, the average days below previous high is 79 days, which is higher, thus worse than the value of 36 days from the benchmark.
