'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.'

Which means for our asset as example:- Compared with the benchmark SPY (61.9%) in the period of the last 5 years, the total return of % of Amplify Lithium & Battery Technology ETF is lower, thus worse.
- Compared with SPY (79.4%) in the period of the last 3 years, the total return, or increase in value of 110.5% is higher, thus better.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (10.1%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of % of Amplify Lithium & Battery Technology ETF is lower, thus worse.
- During the last 3 years, the annual performance (CAGR) is 28.2%, which is higher, thus better than the value of 21.5% from the benchmark.

'Volatility is a statistical measure of the dispersion of returns for a given security or market index. Volatility can either be measured by using the standard deviation or variance between returns from that same security or market index. Commonly, the higher the volatility, the riskier the security. In the securities markets, volatility is often associated with big swings in either direction. For example, when the stock market rises and falls more than one percent over a sustained period of time, it is called a 'volatile' market.'

Using this definition on our asset we see for example:- The volatility over 5 years of Amplify Lithium & Battery Technology ETF is %, which is lower, thus better compared to the benchmark SPY (21.5%) in the same period.
- Looking at historical 30 days volatility in of 33.8% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (21.2%).

'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:- Compared with the benchmark SPY (15.5%) in the period of the last 5 years, the downside risk of % of Amplify Lithium & Battery Technology ETF is smaller, thus better.
- During the last 3 years, the downside risk is 22.6%, which is higher, thus worse than the value of 14.1% from the benchmark.

'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.'

Which means for our asset as example:- The risk / return profile (Sharpe) over 5 years of Amplify Lithium & Battery Technology ETF is , which is smaller, thus worse compared to the benchmark SPY (0.36) in the same period.
- During the last 3 years, the risk / return profile (Sharpe) is 0.76, which is smaller, thus worse than the value of 0.9 from the benchmark.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (0.49) in the period of the last 5 years, the excess return divided by the downside deviation of of Amplify Lithium & Battery Technology ETF is smaller, thus worse.
- Looking at downside risk / excess return profile in of 1.14 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (1.35).

'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 lower, thus better compared to the benchmark SPY (9.15 ) in the same period.
- During the last 3 years, the Ulcer Index is 19 , which is higher, thus worse than the value of 9.78 from the benchmark.

'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:- Looking at the maximum DrawDown 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 -40.5 days in the period of the last 3 years, we see it is relatively smaller, thus worse 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.'

Which means for our asset as example:- Compared with the benchmark SPY (305 days) in the period of the last 5 years, the maximum time in days below previous high water mark of days of Amplify Lithium & Battery Technology ETF is smaller, thus better.
- During the last 3 years, the maximum time in days below previous high water mark is 343 days, which is higher, thus worse than the value of 305 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.'

Applying this definition to our asset in some examples:- The average days under water over 5 years of Amplify Lithium & Battery Technology ETF is days, which is lower, thus better compared to the benchmark SPY (65 days) in the same period.
- During the last 3 years, the average time in days below previous high water mark is 110 days, which is larger, thus worse than the value of 80 days from the benchmark.
