TotalReturn:

'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.'

• Compared with the benchmark SPY (113.2%) in the period of the last 5 years, the total return, or performance of 39.8% of Amazon.com is lower, thus worse.
• Looking at total return, or performance in of 92.6% in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (67.5%).

CAGR:

'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.'

• The annual performance (CAGR) over 5 years of Amazon.com is 7%, which is lower, thus worse compared to the benchmark SPY (16.4%) in the same period.
• Compared with SPY (18.9%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 24.6% is larger, thus better.

Volatility:

'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.'

• Compared with the benchmark SPY (17.5%) in the period of the last 5 years, the 30 days standard deviation of 35.5% of Amazon.com is greater, thus worse.
• During the last 3 years, the 30 days standard deviation is 35%, which is larger, thus worse than the value of 17.5% from the benchmark.

DownVol:

'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.'

• The downside deviation over 5 years of Amazon.com is 24.4%, which is greater, thus worse compared to the benchmark SPY (12.1%) in the same period.
• Looking at downside risk in of 23% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (11.6%).

Sharpe:

'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.'

• The Sharpe Ratio over 5 years of Amazon.com is 0.13, which is smaller, thus worse compared to the benchmark SPY (0.79) in the same period.
• During the last 3 years, the ratio of return and volatility (Sharpe) is 0.63, which is smaller, thus worse than the value of 0.94 from the benchmark.

Sortino:

'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.'

• Looking at the ratio of annual return and downside deviation of 0.18 in the last 5 years of Amazon.com, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (1.15)
• Looking at excess return divided by the downside deviation in of 0.96 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (1.42).

Ulcer:

'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.'

• The Downside risk index over 5 years of Amazon.com is 24 , which is higher, thus worse compared to the benchmark SPY (8.48 ) in the same period.
• Looking at Downside risk index in of 17 in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (5.31 ).

MaxDD:

'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.'

• The maximum DrawDown over 5 years of Amazon.com is -56.1 days, which is lower, thus worse compared to the benchmark SPY (-24.5 days) in the same period.
• Looking at maximum reduction from previous high in of -43.5 days in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (-18.8 days).

MaxDuration:

'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'

• The maximum days under water over 5 years of Amazon.com is 693 days, which is greater, thus worse compared to the benchmark SPY (488 days) in the same period.
• Compared with SPY (199 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 269 days is larger, thus worse.

AveDuration:

'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.'

• Looking at the average days under water of 223 days in the last 5 years of Amazon.com, we see it is relatively greater, thus worse in comparison to the benchmark SPY (120 days)
• During the last 3 years, the average time in days below previous high water mark is 70 days, which is higher, thus worse than the value of 47 days from the benchmark.
