'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.'

Which means for our asset as example:- The total return, or increase in value over 5 years of Invesco BuyBack Achievers ETF is 49.3%, which is smaller, thus worse compared to the benchmark SPY (77.6%) in the same period.
- Compared with SPY (53.5%) in the period of the last 3 years, the total return of 38% is smaller, thus worse.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (12.2%) in the period of the last 5 years, the annual return (CAGR) of 8.4% of Invesco BuyBack Achievers ETF is lower, thus worse.
- Compared with SPY (15.4%) in the period of the last 3 years, the annual return (CAGR) of 11.3% is smaller, thus worse.

'Volatility is a rate at which the price of a security increases or decreases for a given set of returns. Volatility is measured by calculating the standard deviation of the annualized returns over a given period of time. It shows the range to which the price of a security may increase or decrease. Volatility measures the risk of a security. It is used in option pricing formula to gauge the fluctuations in the returns of the underlying assets. Volatility indicates the pricing behavior of the security and helps estimate the fluctuations that may happen in a short period of time.'

Using this definition on our asset we see for example:- The volatility over 5 years of Invesco BuyBack Achievers ETF is 14.2%, which is higher, thus worse compared to the benchmark SPY (13.3%) in the same period.
- Looking at 30 days standard deviation in of 13.8% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (13%).

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

Applying this definition to our asset in some examples:- The downside volatility over 5 years of Invesco BuyBack Achievers ETF is 10.4%, which is larger, thus worse compared to the benchmark SPY (9.6%) in the same period.
- Looking at downside volatility in of 10.2% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (9.4%).

'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.'

Using this definition on our asset we see for example:- Looking at the ratio of return and volatility (Sharpe) of 0.41 in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.73)
- Looking at risk / return profile (Sharpe) in of 0.64 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.99).

'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 downside risk / excess return profile over 5 years of Invesco BuyBack Achievers ETF is 0.56, which is lower, thus worse compared to the benchmark SPY (1.01) in the same period.
- Compared with SPY (1.37) in the period of the last 3 years, the ratio of annual return and downside deviation of 0.87 is smaller, thus worse.

'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.'

Which means for our asset as example:- Looking at the Ulcer Index of 6.12 in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (3.97 )
- During the last 3 years, the Downside risk index is 5.47 , which is larger, thus worse than the value of 4.1 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.'

Which means for our asset as example:- Looking at the maximum drop from peak to valley of -21.2 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 (-19.3 days)
- Looking at maximum drop from peak to valley in of -21.2 days in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (-19.3 days).

'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 (187 days) in the period of the last 5 years, the maximum days below previous high of 435 days of Invesco BuyBack Achievers ETF is higher, thus worse.
- Looking at maximum time in days below previous high water mark in of 305 days in the period of the last 3 years, we see it is relatively higher, 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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (42 days) in the period of the last 5 years, the average days under water of 129 days of Invesco BuyBack Achievers ETF is greater, thus worse.
- Compared with SPY (37 days) in the period of the last 3 years, the average time in days below previous high water mark of 80 days is greater, thus worse.
