'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (106.8%) in the period of the last 5 years, the total return, or increase in value of 46.3% of iShares Global Comm Services ETF is lower, thus worse.
- During the last 3 years, the total return, or increase in value is 50.6%, which is lower, thus worse than the value of 71.9% from the benchmark.

'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.'

Which means for our asset as example:- Looking at the annual return (CAGR) of 7.9% in the last 5 years of iShares Global Comm Services ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (15.7%)
- During the last 3 years, the annual return (CAGR) is 14.6%, which is smaller, thus worse than the value of 19.8% from the benchmark.

'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.'

Which means for our asset as example:- Looking at the volatility of 18.1% in the last 5 years of iShares Global Comm Services ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (18.9%)
- During the last 3 years, the historical 30 days volatility is 20.7%, which is smaller, thus better than the value of 21.9% from the benchmark.

'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.'

Using this definition on our asset we see for example:- Looking at the downside volatility of 13.2% in the last 5 years of iShares Global Comm Services ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (13.8%)
- During the last 3 years, the downside risk is 15.1%, which is smaller, thus better than the value of 15.9% from the benchmark.

'The Sharpe ratio is the measure of risk-adjusted return of a financial portfolio. Sharpe ratio is a measure of excess portfolio return over the risk-free rate relative to its standard deviation. Normally, the 90-day Treasury bill rate is taken as the proxy for risk-free rate. A portfolio with a higher Sharpe ratio is considered superior relative to its peers. The measure was named after William F Sharpe, a Nobel laureate and professor of finance, emeritus at Stanford University.'

Using this definition on our asset we see for example:- Looking at the ratio of return and volatility (Sharpe) of 0.3 in the last 5 years of iShares Global Comm Services ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.69)
- During the last 3 years, the ratio of return and volatility (Sharpe) is 0.59, which is smaller, thus worse than the value of 0.79 from the benchmark.

'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.'

Which means for our asset as example:- The downside risk / excess return profile over 5 years of iShares Global Comm Services ETF is 0.41, which is lower, thus worse compared to the benchmark SPY (0.95) in the same period.
- Looking at excess return divided by the downside deviation in of 0.81 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (1.09).

'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.'

Using this definition on our asset we see for example:- Looking at the Ulcer Index of 6.66 in the last 5 years of iShares Global Comm Services ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (5.61 )
- During the last 3 years, the Ulcer Ratio is 6.04 , which is smaller, thus better than the value of 6.08 from the benchmark.

'Maximum drawdown measures the loss in any losing period during a fund’s investment record. It is defined as the percent retrenchment from a fund’s peak value to the fund’s valley value. The drawdown is in effect from the time the fund’s retrenchment begins until a new fund high is reached. The maximum drawdown encompasses both the period from the fund’s peak to the fund’s valley (length), and the time from the fund’s valley to a new fund high (recovery). It measures the largest percentage drawdown that has occurred in any fund’s data record.'

Which means for our asset as example:- The maximum DrawDown over 5 years of iShares Global Comm Services ETF is -27.1 days, which is larger, thus better compared to the benchmark SPY (-33.7 days) in the same period.
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum reduction from previous high of -27.1 days is larger, thus better.

'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.'

Applying this definition to our asset in some examples:- The maximum days under water over 5 years of iShares Global Comm Services ETF is 313 days, which is larger, thus worse compared to the benchmark SPY (139 days) in the same period.
- During the last 3 years, the maximum days under water is 97 days, which is lower, thus better than the value of 119 days from the benchmark.

'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:- The average days below previous high over 5 years of iShares Global Comm Services ETF is 63 days, which is larger, thus worse compared to the benchmark SPY (32 days) in the same period.
- During the last 3 years, the average days under water is 26 days, which is greater, thus worse than the value of 22 days from the benchmark.
