Invesco WilderHill Clean Energy ETF (PBW)

TotalReturn:

'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.'

• The total return, or performance over 5 years of Invesco WilderHill Clean Energy ETF is -23.2%, which is lower, thus worse compared to the benchmark SPY (87.1%) in the same period.
• Looking at total return, or increase in value in of -76.4% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (26.8%).

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.'

• The annual performance (CAGR) over 5 years of Invesco WilderHill Clean Energy ETF is -5.1%, which is lower, thus worse compared to the benchmark SPY (13.4%) in the same period.
• Compared with SPY (8.3%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of -38.3% is lower, 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.'

• Compared with the benchmark SPY (20.9%) in the period of the last 5 years, the 30 days standard deviation of 45.4% of Invesco WilderHill Clean Energy ETF is higher, thus worse.
• Looking at historical 30 days volatility in of 44.1% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (17.3%).

DownVol:

'Downside risk is the financial risk associated with losses. That is, it is the risk of the actual return being below the expected return, or the uncertainty about the magnitude of that difference. 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.'

• Looking at the downside deviation of 31.8% in the last 5 years of Invesco WilderHill Clean Energy ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (15%)
• During the last 3 years, the downside deviation is 31.1%, which is higher, thus worse than the value of 12.1% from the benchmark.

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.'

• Compared with the benchmark SPY (0.52) in the period of the last 5 years, the Sharpe Ratio of -0.17 of Invesco WilderHill Clean Energy ETF is lower, thus worse.
• During the last 3 years, the risk / return profile (Sharpe) is -0.93, which is lower, thus worse than the value of 0.33 from the benchmark.

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.'

• The downside risk / excess return profile over 5 years of Invesco WilderHill Clean Energy ETF is -0.24, which is lower, thus worse compared to the benchmark SPY (0.72) in the same period.
• Compared with SPY (0.48) in the period of the last 3 years, the excess return divided by the downside deviation of -1.31 is lower, thus worse.

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.'

• The Downside risk index over 5 years of Invesco WilderHill Clean Energy ETF is 50 , which is higher, thus worse compared to the benchmark SPY (9.33 ) in the same period.
• During the last 3 years, the Ulcer Ratio is 50 , which is greater, thus worse than the value of 10 from the benchmark.

MaxDD:

'Maximum drawdown is defined as the peak-to-trough decline of an investment during a specific period. It is usually quoted as a percentage of the peak value. The maximum drawdown can be calculated based on absolute returns, in order to identify strategies that suffer less during market downturns, such as low-volatility strategies. However, the maximum drawdown can also be calculated based on returns relative to a benchmark index, for identifying strategies that show steady outperformance over time.'

• Looking at the maximum reduction from previous high of -84.6 days in the last 5 years of Invesco WilderHill Clean Energy ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (-33.7 days)
• Looking at maximum drop from peak to valley in of -78.3 days in the period of the last 3 years, we see it is relatively lower, thus worse 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). 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'

• The maximum time in days below previous high water mark over 5 years of Invesco WilderHill Clean Energy ETF is 805 days, which is higher, thus worse compared to the benchmark SPY (488 days) in the same period.
• Compared with SPY (488 days) in the period of the last 3 years, the maximum days below previous high of 616 days is greater, thus worse.

AveDuration:

'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.'

• Compared with the benchmark SPY (122 days) in the period of the last 5 years, the average days under water of 287 days of Invesco WilderHill Clean Energy ETF is larger, thus worse.
• During the last 3 years, the average time in days below previous high water mark is 260 days, which is larger, thus worse than the value of 179 days from the benchmark.
