'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:- Compared with the benchmark SPY (66%) in the period of the last 5 years, the total return, or performance of -12.3% of Exxon Mobil is lower, thus worse.
- Looking at total return, or increase in value in of -11% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (45.6%).

'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:- The annual return (CAGR) over 5 years of Exxon Mobil is -2.6%, which is smaller, thus worse compared to the benchmark SPY (10.7%) in the same period.
- Looking at compounded annual growth rate (CAGR) in of -3.8% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (13.3%).

'Volatility is a statistical measure of the dispersion of returns for a given security or market index. Volatility can either be measured by using the standard deviation or variance between returns from that same security or market index. Commonly, the higher the volatility, the riskier the security. In the securities markets, volatility is often associated with big swings in either direction. For example, when the stock market rises and falls more than one percent over a sustained period of time, it is called a 'volatile' market.'

Using this definition on our asset we see for example:- Looking at the volatility of 18.9% in the last 5 years of Exxon Mobil, we see it is relatively larger, thus worse in comparison to the benchmark SPY (13.4%)
- Looking at historical 30 days volatility in of 17.2% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (12.3%).

'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 deviation of 19.2% in the last 5 years of Exxon Mobil, we see it is relatively greater, thus worse in comparison to the benchmark SPY (14.6%)
- Compared with SPY (13.8%) in the period of the last 3 years, the downside deviation of 18% 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.'

Using this definition on our asset we see for example:- The ratio of return and volatility (Sharpe) over 5 years of Exxon Mobil is -0.27, which is lower, thus worse compared to the benchmark SPY (0.61) in the same period.
- Looking at Sharpe Ratio in of -0.37 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.88).

'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.'

Applying this definition to our asset in some examples:- The downside risk / excess return profile over 5 years of Exxon Mobil is -0.27, which is lower, thus worse compared to the benchmark SPY (0.56) in the same period.
- During the last 3 years, the excess return divided by the downside deviation is -0.35, which is smaller, thus worse than the value of 0.78 from the benchmark.

'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:- The Ulcer Index over 5 years of Exxon Mobil is 14 , which is higher, thus worse compared to the benchmark SPY (3.99 ) in the same period.
- Compared with SPY (4.04 ) in the period of the last 3 years, the Ulcer Ratio of 10 is greater, thus worse.

'A maximum drawdown is the maximum loss from a peak to a trough of a portfolio, before a new peak is attained. Maximum Drawdown is an indicator of downside risk over a specified time period. It can be used both as a stand-alone measure or as an input into other metrics such as 'Return over Maximum Drawdown' and the Calmar Ratio. Maximum Drawdown is expressed in percentage terms.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (-19.3 days) in the period of the last 5 years, the maximum drop from peak to valley of -31.5 days of Exxon Mobil is lower, thus worse.
- Compared with SPY (-19.3 days) in the period of the last 3 years, the maximum DrawDown of -24 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) in days.'

Which means for our asset as example:- The maximum days below previous high over 5 years of Exxon Mobil is 1255 days, which is higher, thus worse compared to the benchmark SPY (187 days) in the same period.
- Compared with SPY (139 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 756 days is higher, thus worse.

'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:- The average days below previous high over 5 years of Exxon Mobil is 628 days, which is larger, thus worse compared to the benchmark SPY (41 days) in the same period.
- During the last 3 years, the average time in days below previous high water mark is 379 days, which is higher, thus worse than the value of 36 days from the benchmark.
