'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.'

Applying this definition to our asset in some examples:- The total return over 5 years of SPDR MidCap Trust Series I is 38.3%, which is lower, thus worse compared to the benchmark SPY (67.5%) in the same period.
- During the last 3 years, the total return, or increase in value is 39.8%, which is greater, thus better than the value of 39.8% from the benchmark.

'The compound annual growth rate isn't a true return rate, but rather a representational figure. It is essentially a number that describes the rate at which an investment would have grown if it had grown the same rate every year and the profits were reinvested at the end of each year. In reality, this sort of performance is unlikely. However, CAGR can be used to smooth returns so that they may be more easily understood when compared to alternative investments.'

Applying this definition to our asset in some examples:- Looking at the compounded annual growth rate (CAGR) of 6.7% in the last 5 years of SPDR MidCap Trust Series I, we see it is relatively lower, thus worse in comparison to the benchmark SPY (10.9%)
- Looking at annual performance (CAGR) in of 11.8% in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (11.8%).

'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.'

Using this definition on our asset we see for example:- The volatility over 5 years of SPDR MidCap Trust Series I is 25.3%, which is higher, thus worse compared to the benchmark SPY (21.4%) in the same period.
- Looking at volatility in of 22% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (18.7%).

'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 18.3% in the last 5 years of SPDR MidCap Trust Series I, we see it is relatively greater, thus worse in comparison to the benchmark SPY (15.4%)
- Compared with SPY (13.3%) in the period of the last 3 years, the downside risk of 15.4% is larger, 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.'

Which means for our asset as example:- Looking at the risk / return profile (Sharpe) of 0.17 in the last 5 years of SPDR MidCap Trust Series I, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.39)
- During the last 3 years, the Sharpe Ratio is 0.42, which is lower, thus worse than the value of 0.5 from the benchmark.

'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:- The excess return divided by the downside deviation over 5 years of SPDR MidCap Trust Series I is 0.23, which is smaller, thus worse compared to the benchmark SPY (0.54) in the same period.
- Compared with SPY (0.7) in the period of the last 3 years, the downside risk / excess return profile of 0.61 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:- Compared with the benchmark SPY (9.48 ) in the period of the last 5 years, the Downside risk index of 11 of SPDR MidCap Trust Series I is greater, thus worse.
- During the last 3 years, the Ulcer Index is 9.85 , which is lower, thus better than the value of 10 from the benchmark.

'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.'

Which means for our asset as example:- The maximum DrawDown over 5 years of SPDR MidCap Trust Series I is -42.2 days, which is smaller, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- Compared with SPY (-24.5 days) in the period of the last 3 years, the maximum DrawDown of -23.8 days is higher, thus better.

'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 (358 days) in the period of the last 5 years, the maximum days under water of 390 days of SPDR MidCap Trust Series I is greater, thus worse.
- Compared with SPY (358 days) in the period of the last 3 years, the maximum days under water of 390 days is greater, thus worse.

'The Average 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. 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:- Looking at the average days below previous high of 124 days in the last 5 years of SPDR MidCap Trust Series I, we see it is relatively larger, thus worse in comparison to the benchmark SPY (80 days)
- Compared with SPY (104 days) in the period of the last 3 years, the average time in days below previous high water mark of 117 days is greater, thus worse.
