'The total return on a portfolio of investments takes into account not only the capital appreciation on the portfolio, but also the income received on the portfolio. The income typically consists of interest, dividends, and securities lending fees. This contrasts with the price return, which takes into account only the capital gain on an investment.'

Using this definition on our asset we see for example:- Looking at the total return, or performance of -20.5% in the last 5 years of iShares MSCI South Korea ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (62.7%)
- Compared with SPY (34.7%) in the period of the last 3 years, the total return, or increase in value of -5% is lower, thus worse.

'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 MSCI South Korea ETF is -4.5%, which is lower, thus worse compared to the benchmark SPY (10.2%) in the same period.
- Looking at compounded annual growth rate (CAGR) in of -1.7% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (10.5%).

'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.'

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 27% of iShares MSCI South Korea ETF is greater, thus worse.
- During the last 3 years, the historical 30 days volatility is 30.3%, which is larger, thus worse than the value of 24.1% from the benchmark.

'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:- Looking at the downside deviation of 19.8% in the last 5 years of iShares MSCI South Korea ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (15.3%)
- Compared with SPY (17.6%) in the period of the last 3 years, the downside risk of 22.2% is higher, 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:- Looking at the ratio of return and volatility (Sharpe) of -0.26 in the last 5 years of iShares MSCI South Korea ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.37)
- Compared with SPY (0.33) in the period of the last 3 years, the Sharpe Ratio of -0.14 is lower, thus worse.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (0.51) in the period of the last 5 years, the ratio of annual return and downside deviation of -0.35 of iShares MSCI South Korea ETF is smaller, thus worse.
- Looking at excess return divided by the downside deviation in of -0.19 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.'

Which means for our asset as example:- Looking at the Ulcer Ratio of 21 in the last 5 years of iShares MSCI South Korea ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (7.71 )
- During the last 3 years, the Downside risk index is 19 , 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.'

Applying this definition to our asset in some examples:- Looking at the maximum drop from peak to valley of -49.7 days in the last 5 years of iShares MSCI South Korea ETF, we see it is relatively smaller, 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 reduction from previous high of -49.7 days is lower, thus worse.

'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:- Compared with the benchmark SPY (189 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 712 days of iShares MSCI South Korea ETF is higher, thus worse.
- During the last 3 years, the maximum days below previous high is 437 days, which is greater, thus worse than the value of 189 days from the benchmark.

'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 time in days below previous high water mark over 5 years of iShares MSCI South Korea ETF is 286 days, which is higher, thus worse compared to the benchmark SPY (46 days) in the same period.
- During the last 3 years, the average days below previous high is 152 days, which is higher, thus worse than the value of 45 days from the benchmark.
