Description

The investment seeks investment results that correspond generally to the price and yield of an equity index called the ISE Clean Edge Global Wind EnergyTM Index. The fund will normally invest at least 90% of its net assets (including investment borrowings) in the common stocks and depositary receipts that comprise the index. The index provides a benchmark for investors interested in tracking public companies throughout the world that are active in the wind energy industry. In order to be eligible for inclusion in the index, a security must be issued by a company that is actively engaged in some aspect of the wind energy industry. The fund is non-diversified.

Statistics (YTD)

What do these metrics mean? [Read More] [Hide]

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (121.6%) in the period of the last 5 years, the total return, or increase in value of 90.2% of First Trust Global Wind Energy ETF is smaller, thus worse.
  • Compared with SPY (64.5%) in the period of the last 3 years, the total return of 71.9% is larger, thus better.

CAGR:

'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:
  • The annual return (CAGR) over 5 years of First Trust Global Wind Energy ETF is 13.7%, which is lower, thus worse compared to the benchmark SPY (17.3%) in the same period.
  • During the last 3 years, the annual return (CAGR) is 19.8%, which is greater, thus better than the value of 18.1% from the benchmark.

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.'

Using this definition on our asset we see for example:
  • Looking at the 30 days standard deviation of 20.5% in the last 5 years of First Trust Global Wind Energy ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (18.7%)
  • Compared with SPY (22.5%) in the period of the last 3 years, the volatility of 24.3% is larger, thus worse.

DownVol:

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

Using this definition on our asset we see for example:
  • The downside deviation over 5 years of First Trust Global Wind Energy ETF is 14.8%, which is larger, thus worse compared to the benchmark SPY (13.5%) in the same period.
  • During the last 3 years, the downside volatility is 17.5%, which is greater, thus worse than the value of 16.4% 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.'

Using this definition on our asset we see for example:
  • Looking at the Sharpe Ratio of 0.55 in the last 5 years of First Trust Global Wind Energy ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.79)
  • Looking at Sharpe Ratio in of 0.71 in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (0.69).

Sortino:

'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 First Trust Global Wind Energy ETF is 0.76, which is smaller, thus worse compared to the benchmark SPY (1.09) in the same period.
  • Looking at downside risk / excess return profile in of 0.99 in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (0.95).

Ulcer:

'The Ulcer Index is a technical indicator that measures downside risk, in terms of both the depth and duration of price declines. The index increases in value as the price moves farther away from a recent high and falls as the price rises to new highs. The indicator is usually calculated over a 14-day period, with the Ulcer Index showing the percentage drawdown a trader can expect from the high over that period. The greater the value of the Ulcer Index, the longer it takes for a stock to get back to the former high.'

Which means for our asset as example:
  • Looking at the Downside risk index of 9.01 in the last 5 years of First Trust Global Wind Energy ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (5.58 )
  • Looking at Ulcer Ratio in of 9.83 in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (6.83 ).

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.'

Using this definition on our asset we see for example:
  • Looking at the maximum reduction from previous high of -34.7 days in the last 5 years of First Trust Global Wind Energy 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 -34.7 days is smaller, thus worse.

MaxDuration:

'The Maximum 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. It is the length of time the account was in the Max Drawdown. A Max Drawdown measures a retrenchment from when an equity curve reaches a new high. It’s the maximum an account lost during that retrenchment. This method is applied because a valley can’t be measured until a new high occurs. Once the new high is reached, the percentage change from the old high to the bottom of the largest trough is recorded.'

Using this definition on our asset we see for example:
  • Looking at the maximum days under water of 280 days in the last 5 years of First Trust Global Wind Energy ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (139 days)
  • During the last 3 years, the maximum time in days below previous high water mark is 141 days, which is higher, thus worse than the value of 139 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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (33 days) in the period of the last 5 years, the average days under water of 68 days of First Trust Global Wind Energy ETF is larger, thus worse.
  • Looking at average days under water in of 45 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (35 days).
