Invesco WilderHill Clean Energy ETF (PBW)

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.'

• Compared with the benchmark SPY (82.8%) in the period of the last 5 years, the total return of -55.8% of Invesco WilderHill Clean Energy ETF is lower, thus worse.
• Looking at total return, or performance in of -5.7% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (80.4%).

CAGR:

'The compound annual growth rate isn't a true return rate, but rather a representational figure. It is essentially a number that describes the rate at which an investment would have grown if it had grown the same rate every year and the profits were reinvested at the end of each year. In reality, this sort of performance is unlikely. However, CAGR can be used to smooth returns so that they may be more easily understood when compared to alternative investments.'

• Looking at the compounded annual growth rate (CAGR) of -15.1% 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 (12.9%)
• Compared with SPY (21.8%) in the period of the last 3 years, the annual return (CAGR) of -2% 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 (17.2%) in the period of the last 5 years, the 30 days standard deviation of 43.6% of Invesco WilderHill Clean Energy ETF is higher, thus worse.
• Compared with SPY (15.3%) in the period of the last 3 years, the historical 30 days volatility of 41.8% is greater, thus worse.

DownVol:

'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 30.3% 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 (11.8%)
• Compared with SPY (10.2%) in the period of the last 3 years, the downside volatility of 28.8% is larger, thus worse.

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 -0.4 in the last 5 years of Invesco WilderHill Clean Energy ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.6)
• Looking at risk / return profile (Sharpe) in of -0.11 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (1.26).

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.'

• Compared with the benchmark SPY (0.88) in the period of the last 5 years, the ratio of annual return and downside deviation of -0.58 of Invesco WilderHill Clean Energy ETF is smaller, thus worse.
• Compared with SPY (1.89) in the period of the last 3 years, the downside risk / excess return profile of -0.16 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.'

• Compared with the benchmark SPY (8.45 ) in the period of the last 5 years, the Ulcer Index of 62 of Invesco WilderHill Clean Energy ETF is higher, thus worse.
• Looking at Downside risk index in of 34 in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (3.37 ).

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.'

• Compared with the benchmark SPY (-24.5 days) in the period of the last 5 years, the maximum reduction from previous high of -84.5 days of Invesco WilderHill Clean Energy ETF is lower, thus worse.
• During the last 3 years, the maximum reduction from previous high is -62.3 days, which is smaller, thus worse than the value of -18.8 days from the benchmark.

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.'

• Looking at the maximum time in days below previous high water mark of 1205 days in the last 5 years of Invesco WilderHill Clean Energy ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (488 days)
• During the last 3 years, the maximum days under water is 533 days, which is greater, thus worse than the value of 87 days from the benchmark.

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.'

• The average time in days below previous high water mark over 5 years of Invesco WilderHill Clean Energy ETF is 584 days, which is larger, thus worse compared to the benchmark SPY (118 days) in the same period.
• Looking at average days under water in of 201 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (18 days).
