'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 (67.7%) in the period of the last 5 years, the total return, or increase in value of % of Amplify Lithium & Battery Technology ETF is smaller, thus worse.
- During the last 3 years, the total return, or performance is 43.4%, which is greater, thus better than the value of 37% from the benchmark.

'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 performance (CAGR) over 5 years of Amplify Lithium & Battery Technology ETF is %, which is lower, thus worse compared to the benchmark SPY (10.9%) in the same period.
- Compared with SPY (11.1%) in the period of the last 3 years, the annual performance (CAGR) of 12.8% is greater, thus better.

'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:- Compared with the benchmark SPY (21.4%) in the period of the last 5 years, the 30 days standard deviation of % of Amplify Lithium & Battery Technology ETF is smaller, thus better.
- Looking at volatility in of 36.3% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (24.8%).

'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.'

Which means for our asset as example:- Looking at the downside deviation of % in the last 5 years of Amplify Lithium & Battery Technology ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (15.5%)
- During the last 3 years, the downside volatility is 25.8%, which is higher, thus worse than the value of 17.9% from the benchmark.

'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:- Looking at the ratio of return and volatility (Sharpe) of in the last 5 years of Amplify Lithium & Battery Technology ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.39)
- Looking at risk / return profile (Sharpe) in of 0.28 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.34).

'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:- The ratio of annual return and downside deviation over 5 years of Amplify Lithium & Battery Technology ETF is , which is lower, thus worse compared to the benchmark SPY (0.54) in the same period.
- Compared with SPY (0.48) in the period of the last 3 years, the downside risk / excess return profile of 0.4 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.'

Which means for our asset as example:- The Downside risk index over 5 years of Amplify Lithium & Battery Technology ETF is , which is smaller, thus better compared to the benchmark SPY (8.47 ) in the same period.
- Looking at Ulcer Ratio in of 20 in the period of the last 3 years, we see it is relatively greater, thus worse 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.'

Which means for our asset as example:- Looking at the maximum reduction from previous high of days in the last 5 years of Amplify Lithium & Battery Technology ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (-33.7 days)
- Looking at maximum drop from peak to valley in of -50 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.'

Applying this definition to our asset in some examples:- The maximum days under water over 5 years of Amplify Lithium & Battery Technology ETF is days, which is lower, thus better compared to the benchmark SPY (231 days) in the same period.
- During the last 3 years, the maximum days below previous high is 269 days, which is higher, thus worse than the value of 231 days from the benchmark.

'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.'

Using this definition on our asset we see for example:- Looking at the average time in days below previous high water mark of days in the last 5 years of Amplify Lithium & Battery Technology ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (54 days)
- Looking at average time in days below previous high water mark in of 103 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (58 days).
