'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.'

Which means for our asset as example:- Looking at the total return of 243.9% in the last 5 years of O'Reilly Automotive, we see it is relatively greater, thus better 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 performance of 86.8% is greater, thus better.

'The compound annual growth rate (CAGR) is a useful measure of growth over multiple time periods. It can be thought of as the growth rate that gets you from the initial investment value to the ending investment value if you assume that the investment has been compounding over the time period.'

Applying this definition to our asset in some examples:- Looking at the annual performance (CAGR) of 28.1% in the last 5 years of O'Reilly Automotive, we see it is relatively larger, thus better in comparison to the benchmark SPY (10.2%)
- Looking at annual performance (CAGR) in of 23.2% in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (10.5%).

'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 (20.9%) in the period of the last 5 years, the 30 days standard deviation of 29.6% of O'Reilly Automotive is higher, thus worse.
- Looking at 30 days standard deviation in of 31.8% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (24.1%).

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (15.3%) in the period of the last 5 years, the downside volatility of 20.5% of O'Reilly Automotive is larger, thus worse.
- Compared with SPY (17.6%) in the period of the last 3 years, the downside volatility of 22.8% is greater, thus worse.

'The Sharpe ratio (also known as the Sharpe index, the Sharpe measure, and the reward-to-variability ratio) is a way to examine the performance of an investment by adjusting for its risk. The ratio measures the excess return (or risk premium) per unit of deviation in an investment asset or a trading strategy, typically referred to as risk, named after William F. Sharpe.'

Applying this definition to our asset in some examples:- The Sharpe Ratio over 5 years of O'Reilly Automotive is 0.86, which is greater, thus better compared to the benchmark SPY (0.37) in the same period.
- During the last 3 years, the risk / return profile (Sharpe) is 0.65, which is greater, thus better than the value of 0.33 from the benchmark.

'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:- Compared with the benchmark SPY (0.51) in the period of the last 5 years, the excess return divided by the downside deviation of 1.25 of O'Reilly Automotive is higher, thus better.
- Compared with SPY (0.45) in the period of the last 3 years, the ratio of annual return and downside deviation of 0.91 is greater, thus better.

'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.'

Using this definition on our asset we see for example:- Looking at the Downside risk index of 8.01 in the last 5 years of O'Reilly Automotive, we see it is relatively greater, thus worse in comparison to the benchmark SPY (7.71 )
- Looking at Ulcer Index in of 9.09 in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (9.08 ).

'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:- The maximum reduction from previous high over 5 years of O'Reilly Automotive is -42 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- During the last 3 years, the maximum drop from peak to valley is -42 days, which is lower, thus worse than the value of -33.7 days from the benchmark.

'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 O'Reilly Automotive is 168 days, which is lower, thus better compared to the benchmark SPY (189 days) in the same period.
- Compared with SPY (189 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 168 days is lower, thus better.

'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 under water over 5 years of O'Reilly Automotive is 41 days, which is lower, thus better compared to the benchmark SPY (46 days) in the same period.
- Looking at average time in days below previous high water mark in of 45 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (45 days).
