'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.'

Which means for our asset as example:- Compared with the benchmark SPY (60.9%) in the period of the last 5 years, the total return, or performance of 40% of iShares Edge MSCI Min Vol Global ETF is smaller, thus worse.
- Looking at total return, or performance in of 19.1% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (34.2%).

'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.'

Which means for our asset as example:- Looking at the annual performance (CAGR) of 7% in the last 5 years of iShares Edge MSCI Min Vol Global ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (10%)
- Looking at compounded annual growth rate (CAGR) in of 6.1% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (10.3%).

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (18.7%) in the period of the last 5 years, the 30 days standard deviation of 14.3% of iShares Edge MSCI Min Vol Global ETF is lower, thus better.
- Looking at volatility in of 16.3% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (21.5%).

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

Applying this definition to our asset in some examples:- Looking at the downside deviation of 10.5% in the last 5 years of iShares Edge MSCI Min Vol Global ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (13.6%)
- Looking at downside deviation in of 12% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (15.7%).

'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 (0.4) in the period of the last 5 years, the risk / return profile (Sharpe) of 0.31 of iShares Edge MSCI Min Vol Global ETF is lower, thus worse.
- Compared with SPY (0.36) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of 0.22 is smaller, thus worse.

'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.'

Using this definition on our asset we see for example:- The downside risk / excess return profile over 5 years of iShares Edge MSCI Min Vol Global ETF is 0.43, which is lower, thus worse compared to the benchmark SPY (0.55) in the same period.
- Looking at excess return divided by the downside deviation in of 0.3 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.5).

'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.'

Applying this definition to our asset in some examples:- Looking at the Ulcer Index of 4.6 in the last 5 years of iShares Edge MSCI Min Vol Global ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (5.82 )
- Compared with SPY (6.86 ) in the period of the last 3 years, the Downside risk index of 5.27 is smaller, thus better.

'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:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum drop from peak to valley of -28.8 days of iShares Edge MSCI Min Vol Global ETF is larger, thus better.
- Looking at maximum DrawDown in of -28.8 days in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (-33.7 days).

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 157 days of iShares Edge MSCI Min Vol Global ETF is lower, thus better.
- Looking at maximum time in days below previous high water mark in of 157 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (139 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.'

Applying this definition to our asset in some examples:- The average days below previous high over 5 years of iShares Edge MSCI Min Vol Global ETF is 41 days, which is lower, thus better compared to the benchmark SPY (43 days) in the same period.
- During the last 3 years, the average days below previous high is 36 days, which is lower, thus better than the value of 39 days from the benchmark.
