Invesco BuyBack Achievers ETF (PKW)

TotalReturn:

'Total return is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investment’s overall performance.'

• Looking at the total return of 75.3% in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (87.4%)
• Compared with SPY (26.8%) in the period of the last 3 years, the total return, or performance of 22.7% is smaller, thus worse.

CAGR:

'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.'

• Compared with the benchmark SPY (13.4%) in the period of the last 5 years, the annual performance (CAGR) of 11.9% of Invesco BuyBack Achievers ETF is smaller, thus worse.
• Compared with SPY (8.2%) in the period of the last 3 years, the annual performance (CAGR) of 7.1% is smaller, thus worse.

Volatility:

'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.'

• Looking at the historical 30 days volatility of 23.8% in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (20.9%)
• Looking at volatility in of 18% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (17.3%).

DownVol:

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

• Looking at the downside risk of 16.8% in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (15%)
• Looking at downside volatility in of 12.6% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (12.1%).

Sharpe:

'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.'

• Looking at the ratio of return and volatility (Sharpe) of 0.39 in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.52)
• Compared with SPY (0.33) in the period of the last 3 years, the risk / return profile (Sharpe) of 0.25 is lower, thus worse.

Sortino:

'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.'

• Looking at the downside risk / excess return profile of 0.56 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 downside risk / excess return profile in of 0.36 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.47).

Ulcer:

'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.'

• Looking at the Downside risk index of 10 in the last 5 years of Invesco BuyBack Achievers ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (9.33 )
• Looking at Ulcer Index in of 9.22 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (10 ).

MaxDD:

'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.'

• Looking at the maximum DrawDown 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)
• Looking at maximum drop from peak to valley in of -23.5 days in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (-24.5 days).

MaxDuration:

'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.'

• The maximum time in days below previous high water mark over 5 years of Invesco BuyBack Achievers ETF is 527 days, which is larger, thus worse compared to the benchmark SPY (488 days) in the same period.
• During the last 3 years, the maximum days below previous high is 527 days, which is higher, thus worse than the value of 488 days from the benchmark.

AveDuration:

'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.'

• Compared with the benchmark SPY (122 days) in the period of the last 5 years, the average days under water of 147 days of Invesco BuyBack Achievers ETF is larger, thus worse.
• During the last 3 years, the average time in days below previous high water mark is 201 days, which is larger, thus worse than the value of 179 days from the benchmark.
