'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.'

Which means for our asset as example:- Looking at the total return, or increase in value of 29.6% in the last 5 years of iShares Edge MSCI Min Vol Global ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (94.9%)
- Looking at total return, or increase in value in of 8.6% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (22.5%).

'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.'

Which means for our asset as example:- The annual performance (CAGR) over 5 years of iShares Edge MSCI Min Vol Global ETF is 5.3%, which is lower, thus worse compared to the benchmark SPY (14.3%) in the same period.
- During the last 3 years, the annual return (CAGR) is 2.8%, which is lower, thus worse than the value of 7% from the benchmark.

'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.'

Which means for our asset as example:- The historical 30 days volatility over 5 years of iShares Edge MSCI Min Vol Global ETF is 14.9%, which is lower, thus better compared to the benchmark SPY (20.9%) in the same period.
- Looking at 30 days standard deviation in of 10.7% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (17.5%).

'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%) in the period of the last 5 years, the downside deviation of 10.9% of iShares Edge MSCI Min Vol Global ETF is lower, thus better.
- Compared with SPY (12.3%) in the period of the last 3 years, the downside deviation of 7.6% is lower, thus better.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (0.56) in the period of the last 5 years, the risk / return profile (Sharpe) of 0.19 of iShares Edge MSCI Min Vol Global ETF is smaller, thus worse.
- Compared with SPY (0.26) in the period of the last 3 years, the risk / return profile (Sharpe) of 0.03 is lower, 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.'

Which means for our asset as example:- Compared with the benchmark SPY (0.79) in the period of the last 5 years, the excess return divided by the downside deviation of 0.26 of iShares Edge MSCI Min Vol Global ETF is smaller, thus worse.
- Looking at excess return divided by the downside deviation in of 0.04 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.37).

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (9.32 ) in the period of the last 5 years, the Downside risk index of 7.21 of iShares Edge MSCI Min Vol Global ETF is smaller, thus better.
- Looking at Downside risk index in of 7.51 in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (10 ).

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum reduction from previous high of -28.8 days of iShares Edge MSCI Min Vol Global ETF is larger, thus better.
- Compared with SPY (-24.5 days) in the period of the last 3 years, the maximum drop from peak to valley of -18.1 days is higher, 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). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred. But that isn’t always the case. The Max DD duration is the longest time between peaks, period. So it could be the time when the program also had its biggest peak to valley loss (and usually is, because the program needs a long time to recover from the largest loss), but it doesn’t have to be'

Applying this definition to our asset in some examples:- Looking at the maximum time in days below previous high water mark of 536 days in the last 5 years of iShares Edge MSCI Min Vol Global ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (488 days)
- Looking at maximum days below previous high in of 536 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (488 days).

'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.'

Applying this definition to our asset in some examples:- Looking at the average days under water of 151 days in the last 5 years of iShares Edge MSCI Min Vol Global ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (123 days)
- Looking at average days below previous high in of 205 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (179 days).
