'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 increase in value of 7.5% 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 (67.9%)
- Compared with SPY (44.5%) in the period of the last 3 years, the total return of 2.8% is smaller, 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.'

Which means for our asset as example:- The annual return (CAGR) over 5 years of PIMCO Enhanced Short Maturity ETF is 1.5%, which is lower, thus worse compared to the benchmark SPY (10.9%) in the same period.
- Looking at annual performance (CAGR) in of 0.9% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (13.1%).

'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 30 days standard deviation over 5 years of PIMCO Enhanced Short Maturity ETF is 1.3%, which is smaller, thus better compared to the benchmark SPY (21.4%) in the same period.
- During the last 3 years, the 30 days standard deviation is 0.7%, which is lower, thus better than the value of 18.7% from the benchmark.

'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:- Looking at the downside deviation of 1.1% 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 (15.4%)
- Looking at downside volatility in of 0.5% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (13.3%).

'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:- Compared with the benchmark SPY (0.39) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of -0.8 of PIMCO Enhanced Short Maturity ETF is lower, thus worse.
- Compared with SPY (0.56) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of -2.2 is lower, thus worse.

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Using this definition on our asset we see for example:- Looking at the excess return divided by the downside deviation of -0.98 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 (0.55)
- Compared with SPY (0.79) in the period of the last 3 years, the ratio of annual return and downside deviation of -3.16 is lower, thus worse.

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (9.47 ) in the period of the last 5 years, the Ulcer Ratio of 0.89 of PIMCO Enhanced Short Maturity ETF is lower, thus better.
- Looking at Ulcer Index in of 1.03 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (10 ).

'Maximum drawdown measures the loss in any losing period during a fund’s investment record. It is defined as the percent retrenchment from a fund’s peak value to the fund’s valley value. The drawdown is in effect from the time the fund’s retrenchment begins until a new fund high is reached. The maximum drawdown encompasses both the period from the fund’s peak to the fund’s valley (length), and the time from the fund’s valley to a new fund high (recovery). It measures the largest percentage drawdown that has occurred in any fund’s data record.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum DrawDown of -4.6 days of PIMCO Enhanced Short Maturity ETF is higher, thus better.
- Looking at maximum reduction from previous high in of -2.4 days in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (-24.5 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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (354 days) in the period of the last 5 years, the maximum days under water of 380 days of PIMCO Enhanced Short Maturity ETF is higher, thus worse.
- Looking at maximum days below previous high in of 380 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (354 days).

'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.'

Which means for our asset as example:- The average days under water over 5 years of PIMCO Enhanced Short Maturity ETF is 100 days, which is larger, thus worse compared to the benchmark SPY (79 days) in the same period.
- Compared with SPY (102 days) in the period of the last 3 years, the average time in days below previous high water mark of 124 days is larger, thus worse.
