'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (58.9%) in the period of the last 5 years, the total return of 13.8% of Amplify Transformational Data Sharing ETF is lower, thus worse.
- Looking at total return, or performance in of 20.1% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (33.9%).

'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 (9.7%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of 2.6% of Amplify Transformational Data Sharing ETF is smaller, thus worse.
- Compared with SPY (10.2%) in the period of the last 3 years, the annual return (CAGR) of 6.3% is smaller, 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.'

Which means for our asset as example:- The 30 days standard deviation over 5 years of Amplify Transformational Data Sharing ETF is 38.2%, which is larger, thus worse compared to the benchmark SPY (21.6%) in the same period.
- Compared with SPY (25%) in the period of the last 3 years, the historical 30 days volatility of 46.8% is greater, thus worse.

'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:- Looking at the downside risk of 27.3% in the last 5 years of Amplify Transformational Data Sharing ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (15.7%)
- Compared with SPY (18.1%) in the period of the last 3 years, the downside deviation of 33.2% is higher, 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 Amplify Transformational Data Sharing ETF is 0, which is smaller, thus worse compared to the benchmark SPY (0.33) in the same period.
- Compared with SPY (0.31) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of 0.08 is lower, 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 ratio of annual return and downside deviation of 0 in the last 5 years of Amplify Transformational Data Sharing ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.46)
- During the last 3 years, the excess return divided by the downside deviation is 0.11, which is smaller, thus worse than the value of 0.43 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:- The Downside risk index over 5 years of Amplify Transformational Data Sharing ETF is 30 , which is greater, thus worse compared to the benchmark SPY (8.91 ) in the same period.
- Looking at Downside risk index in of 37 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (11 ).

'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.'

Applying this definition to our asset in some examples:- The maximum DrawDown over 5 years of Amplify Transformational Data Sharing ETF is -73.3 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- Looking at maximum drop from peak to valley in of -73.3 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-33.7 days).

'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:- Looking at the maximum days below previous high of 415 days in the last 5 years of Amplify Transformational Data Sharing ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (271 days)
- During the last 3 years, the maximum time in days below previous high water mark is 309 days, which is higher, thus worse than the value of 271 days from the benchmark.

'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 132 days in the last 5 years of Amplify Transformational Data Sharing ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (60 days)
- Looking at average time in days below previous high water mark in of 99 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (72 days).
