'Total return is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investment’s overall performance.'

Which means for our asset as example:- Compared with the benchmark SPY (67.6%) in the period of the last 5 years, the total return of -0.6% of PIMCO Enhanced Short Maturity ETF is lower, thus worse.
- During the last 3 years, the total return is 6.9%, which is lower, thus worse than the value of 51.3% from the benchmark.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (10.9%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of -0.1% of PIMCO Enhanced Short Maturity ETF is lower, thus worse.
- Looking at annual performance (CAGR) in of 2.3% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (14.8%).

'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:- Looking at the historical 30 days volatility of 4.1% in the last 5 years of PIMCO Enhanced Short Maturity ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (13.5%)
- Looking at 30 days standard deviation in of 0.3% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (12.8%).

'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 volatility of 7.8% in the last 5 years of PIMCO Enhanced Short Maturity ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (14.8%)
- Compared with SPY (14.7%) in the period of the last 3 years, the downside risk of 0.5% is lower, thus better.

'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.'

Which means for our asset as example:- The Sharpe Ratio over 5 years of PIMCO Enhanced Short Maturity ETF is -0.64, which is lower, thus worse compared to the benchmark SPY (0.62) in the same period.
- Looking at risk / return profile (Sharpe) in of -0.7 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.96).

'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:- Looking at the excess return divided by the downside deviation of -0.33 in the last 5 years of PIMCO Enhanced Short Maturity ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.57)
- During the last 3 years, the ratio of annual return and downside deviation is -0.47, which is lower, thus worse than the value of 0.84 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:- Looking at the Ulcer Index of 6.13 in the last 5 years of PIMCO Enhanced Short Maturity ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (3.99 )
- Compared with SPY (4.1 ) in the period of the last 3 years, the Ulcer Index of 0.03 is lower, thus better.

'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 (-19.3 days) in the period of the last 5 years, the maximum reduction from previous high of -9.2 days of PIMCO Enhanced Short Maturity ETF is higher, thus better.
- Looking at maximum drop from peak to valley in of -0.2 days in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (-19.3 days).

'The Maximum 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. It is the length of time the account was in the Max Drawdown. A Max Drawdown measures a retrenchment from when an equity curve reaches a new high. It’s the maximum an account lost during that retrenchment. This method is applied because a valley can’t be measured until a new high occurs. Once the new high is reached, the percentage change from the old high to the bottom of the largest trough is recorded.'

Which means for our asset as example:- Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum days below previous high of 1158 days of PIMCO Enhanced Short Maturity ETF is higher, thus worse.
- Compared with SPY (139 days) in the period of the last 3 years, the maximum days under water of 30 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.'

Using this definition on our asset we see for example:- The average time in days below previous high water mark over 5 years of PIMCO Enhanced Short Maturity ETF is 541 days, which is larger, thus worse compared to the benchmark SPY (42 days) in the same period.
- During the last 3 years, the average days below previous high is 4 days, which is lower, thus better than the value of 36 days from the benchmark.
