'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 -99.8% in the last 5 years of Mylan N.V., we see it is relatively lower, thus worse in comparison to the benchmark SPY (63%)
- Compared with SPY (31.2%) in the period of the last 3 years, the total return, or performance of -99.8% is lower, thus worse.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (10.3%) in the period of the last 5 years, the annual return (CAGR) of -72.7% of Mylan N.V. is smaller, thus worse.
- Compared with SPY (9.5%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of -87.2% 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:- The volatility over 5 years of Mylan N.V. is 60%, which is larger, thus worse compared to the benchmark SPY (21.4%) in the same period.
- Looking at historical 30 days volatility in of 71.4% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (24.9%).

'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 (15.6%) in the period of the last 5 years, the downside risk of 53.6% of Mylan N.V. is higher, thus worse.
- During the last 3 years, the downside deviation is 65.7%, which is greater, thus worse than the value of 18% from the benchmark.

'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 (0.36) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of -1.25 of Mylan N.V. is smaller, thus worse.
- Compared with SPY (0.28) in the period of the last 3 years, the risk / return profile (Sharpe) of -1.26 is smaller, thus worse.

'The Sortino ratio improves upon the Sharpe ratio by isolating downside volatility from total volatility by dividing excess return by the downside deviation. The Sortino ratio is a variation of the Sharpe ratio that differentiates harmful volatility from total overall volatility by using the asset's standard deviation of negative asset returns, called downside deviation. The Sortino ratio takes the asset's return and subtracts the risk-free rate, and then divides that amount by the asset's downside deviation. The ratio was named after Frank A. Sortino.'

Which means for our asset as example:- Looking at the excess return divided by the downside deviation of -1.4 in the last 5 years of Mylan N.V., we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.5)
- Compared with SPY (0.39) in the period of the last 3 years, the excess return divided by the downside deviation of -1.36 is lower, thus worse.

'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:- Looking at the Ulcer Ratio of 46 in the last 5 years of Mylan N.V., we see it is relatively greater, thus worse in comparison to the benchmark SPY (8.49 )
- Compared with SPY (10 ) in the period of the last 3 years, the Downside risk index of 49 is larger, 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:- The maximum reduction from previous high over 5 years of Mylan N.V. is -99.9 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum DrawDown of -99.8 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 (233 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 1232 days of Mylan N.V. is larger, thus worse.
- Compared with SPY (233 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 713 days is larger, 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.'

Using this definition on our asset we see for example:- Looking at the average days under water of 607 days in the last 5 years of Mylan N.V., we see it is relatively greater, thus worse in comparison to the benchmark SPY (54 days)
- Looking at average time in days below previous high water mark in of 346 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (59 days).
