TotalReturn:

'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.'

• The total return over 5 years of Amazon.com is 234.7%, which is greater, thus better compared to the benchmark SPY (106.8%) in the same period.
• Looking at total return, or performance in of 67.6% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (71.9%).

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 return (CAGR) over 5 years of Amazon.com is 27.4%, which is greater, thus better compared to the benchmark SPY (15.7%) in the same period.
• Looking at annual return (CAGR) in of 18.8% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (19.8%).

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.'

• The volatility over 5 years of Amazon.com is 29.7%, which is higher, thus worse compared to the benchmark SPY (18.9%) in the same period.
• Compared with SPY (21.9%) in the period of the last 3 years, the 30 days standard deviation of 29.4% is greater, thus worse.

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.'

• Compared with the benchmark SPY (13.8%) in the period of the last 5 years, the downside risk of 20% of Amazon.com is greater, thus worse.
• During the last 3 years, the downside risk is 20%, which is higher, thus worse than the value of 15.9% from the benchmark.

Sharpe:

'The Sharpe ratio was developed by Nobel laureate William F. Sharpe, and is used to help investors understand the return of an investment compared to its risk. The ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. Subtracting the risk-free rate from the mean return allows an investor to better isolate the profits associated with risk-taking activities. One intuition of this calculation is that a portfolio engaging in 'zero risk' investments, such as the purchase of U.S. Treasury bills (for which the expected return is the risk-free rate), has a Sharpe ratio of exactly zero. Generally, the greater the value of the Sharpe ratio, the more attractive the risk-adjusted return.'

• Looking at the ratio of return and volatility (Sharpe) of 0.84 in the last 5 years of Amazon.com, we see it is relatively larger, thus better in comparison to the benchmark SPY (0.69)
• Looking at ratio of return and volatility (Sharpe) in of 0.55 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.79).

Sortino:

'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.'

• The ratio of annual return and downside deviation over 5 years of Amazon.com is 1.24, which is higher, thus better compared to the benchmark SPY (0.95) in the same period.
• Looking at excess return divided by the downside deviation in of 0.81 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (1.09).

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.'

• Compared with the benchmark SPY (5.61 ) in the period of the last 5 years, the Ulcer Ratio of 9.57 of Amazon.com is greater, thus worse.
• Compared with SPY (6.08 ) in the period of the last 3 years, the Downside risk index of 8.7 is higher, thus worse.

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 -34.1 days, which is smaller, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
• Looking at maximum reduction from previous high in of -25 days in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (-33.7 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) in days.'

• The maximum time in days below previous high water mark over 5 years of Amazon.com is 355 days, which is larger, thus worse compared to the benchmark SPY (139 days) in the same period.
• During the last 3 years, the maximum days under water is 209 days, which is larger, thus worse than the value of 119 days from the benchmark.

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.'

• The average time in days below previous high water mark over 5 years of Amazon.com is 90 days, which is higher, thus worse compared to the benchmark SPY (32 days) in the same period.
• During the last 3 years, the average days below previous high is 63 days, which is greater, thus worse than the value of 22 days from the benchmark.
