'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.'

Using this definition on our asset we see for example:- Looking at the total return, or increase in value of 11.8% in the last 5 years of iShares MSCI Global Gold Miners ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (62.7%)
- During the last 3 years, the total return, or performance is -7.1%, which is smaller, thus worse than the value of 34.7% 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.'

Applying this definition to our asset in some examples:- The compounded annual growth rate (CAGR) over 5 years of iShares MSCI Global Gold Miners ETF is 2.3%, which is lower, thus worse compared to the benchmark SPY (10.2%) in the same period.
- Compared with SPY (10.5%) in the period of the last 3 years, the annual return (CAGR) of -2.4% is lower, thus worse.

'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:- Compared with the benchmark SPY (20.9%) in the period of the last 5 years, the 30 days standard deviation of 35.4% of iShares MSCI Global Gold Miners ETF is larger, thus worse.
- Compared with SPY (24.1%) in the period of the last 3 years, the volatility of 40.5% is greater, thus worse.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (15.3%) in the period of the last 5 years, the downside volatility of 24.4% of iShares MSCI Global Gold Miners ETF is larger, thus worse.
- Compared with SPY (17.6%) in the period of the last 3 years, the downside volatility of 28.1% is greater, thus worse.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (0.37) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of -0.01 of iShares MSCI Global Gold Miners ETF is lower, thus worse.
- During the last 3 years, the Sharpe Ratio is -0.12, which is lower, thus worse than the value of 0.33 from the benchmark.

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Which means for our asset as example:- The downside risk / excess return profile over 5 years of iShares MSCI Global Gold Miners ETF is -0.01, which is lower, thus worse compared to the benchmark SPY (0.51) in the same period.
- Looking at ratio of annual return and downside deviation in of -0.18 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.45).

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (7.71 ) in the period of the last 5 years, the Ulcer Index of 20 of iShares MSCI Global Gold Miners ETF is higher, thus worse.
- During the last 3 years, the Downside risk index is 23 , which is higher, thus worse than the value of 9.08 from the benchmark.

'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 DrawDown of -52 days in the last 5 years of iShares MSCI Global Gold Miners ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (-33.7 days)
- Looking at maximum DrawDown in of -52 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-33.7 days).

'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 time in days below previous high water mark over 5 years of iShares MSCI Global Gold Miners ETF is 545 days, which is larger, thus worse compared to the benchmark SPY (189 days) in the same period.
- Looking at maximum time in days below previous high water mark in of 545 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (189 days).

'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.'

Which means for our asset as example:- The average time in days below previous high water mark over 5 years of iShares MSCI Global Gold Miners ETF is 182 days, which is greater, thus worse compared to the benchmark SPY (46 days) in the same period.
- Compared with SPY (45 days) in the period of the last 3 years, the average days under water of 208 days is greater, thus worse.
