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 59.4%, which is smaller, thus worse compared to the benchmark SPY (109.8%) in the same period.
• Compared with SPY (42.5%) in the period of the last 3 years, the total return, or performance of 64.4% is higher, thus better.

CAGR:

'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.'

• Compared with the benchmark SPY (16%) in the period of the last 5 years, the annual return (CAGR) of 9.8% of Amazon.com is lower, thus worse.
• During the last 3 years, the annual performance (CAGR) is 18.1%, which is higher, thus better than the value of 12.6% from the benchmark.

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 historical 30 days volatility over 5 years of Amazon.com is 35.5%, which is greater, thus worse compared to the benchmark SPY (17.9%) in the same period.
• Compared with SPY (18.4%) in the period of the last 3 years, the 30 days standard deviation of 36.5% is higher, thus worse.

DownVol:

'The downside volatility is similar to the volatility, or standard deviation, but only takes losing/negative periods into account.'

• Looking at the downside volatility of 24.4% in the last 5 years of Amazon.com, we see it is relatively greater, thus worse in comparison to the benchmark SPY (12.5%)
• During the last 3 years, the downside risk is 24.6%, which is greater, thus worse than the value of 12.6% from the benchmark.

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 risk / return profile (Sharpe) over 5 years of Amazon.com is 0.21, which is lower, thus worse compared to the benchmark SPY (0.75) in the same period.
• Compared with SPY (0.55) in the period of the last 3 years, the Sharpe Ratio of 0.43 is lower, thus worse.

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 0.3 in the last 5 years of Amazon.com, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (1.08)
• Looking at downside risk / excess return profile in of 0.64 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.8).

Ulcer:

'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.'

• The Ulcer Ratio over 5 years of Amazon.com is 24 , which is greater, 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 (5.54 ).

MaxDD:

'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.'

• Compared with the benchmark SPY (-24.5 days) in the period of the last 5 years, the maximum DrawDown of -56.1 days of Amazon.com is lower, thus worse.
• During the last 3 years, the maximum DrawDown is -43.5 days, which is smaller, thus worse than the value of -18.8 days from the benchmark.

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.'

• Compared with the benchmark SPY (488 days) in the period of the last 5 years, the maximum days below previous high of 693 days of Amazon.com is higher, thus worse.
• Looking at maximum days below previous high in of 269 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (199 days).

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.'

• Compared with the benchmark SPY (119 days) in the period of the last 5 years, the average time in days below previous high water mark of 223 days of Amazon.com is greater, thus worse.
• Looking at average time in days below previous high water mark in of 66 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (44 days).
