Align Technology (ALGN)

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.'

• Looking at the total return, or increase in value of 239.9% in the last 5 years of Align Technology, we see it is relatively higher, thus better in comparison to the benchmark SPY (64.1%)
• Looking at total return in of 98.2% in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (48.1%).

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 (10.4%) in the period of the last 5 years, the annual return (CAGR) of 27.7% of Align Technology is greater, thus better.
• Compared with SPY (14%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 25.6% 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 (13.6%) in the period of the last 5 years, the 30 days standard deviation of 37.6% of Align Technology is higher, thus worse.
• Looking at historical 30 days volatility in of 42.1% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (12.8%).

DownVol:

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

• Looking at the downside deviation of 42.9% in the last 5 years of Align Technology, we see it is relatively higher, thus worse in comparison to the benchmark SPY (14.9%)
• Looking at downside deviation in of 49.2% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (14.5%).

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.'

• Compared with the benchmark SPY (0.58) in the period of the last 5 years, the Sharpe Ratio of 0.67 of Align Technology is larger, thus better.
• Looking at Sharpe Ratio in of 0.55 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.9).

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.'

• Compared with the benchmark SPY (0.53) in the period of the last 5 years, the excess return divided by the downside deviation of 0.59 of Align Technology is greater, thus better.
• During the last 3 years, the excess return divided by the downside deviation is 0.47, which is lower, thus worse than the value of 0.79 from the benchmark.

Ulcer:

'The Ulcer Index is a technical indicator that measures downside risk, in terms of both the depth and duration of price declines. The index increases in value as the price moves farther away from a recent high and falls as the price rises to new highs. The indicator is usually calculated over a 14-day period, with the Ulcer Index showing the percentage drawdown a trader can expect from the high over that period. The greater the value of the Ulcer Index, the longer it takes for a stock to get back to the former high.'

• Compared with the benchmark SPY (4.02 ) in the period of the last 5 years, the Ulcer Ratio of 18 of Align Technology is higher, thus worse.
• Compared with SPY (4.09 ) in the period of the last 3 years, the Ulcer Index of 22 is larger, thus worse.

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.'

• The maximum drop from peak to valley over 5 years of Align Technology is -55.9 days, which is lower, thus worse compared to the benchmark SPY (-19.3 days) in the same period.
• Compared with SPY (-19.3 days) in the period of the last 3 years, the maximum DrawDown of -55.9 days is lower, thus worse.

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'

• Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum days below previous high of 248 days of Align Technology is higher, thus worse.
• Compared with SPY (139 days) in the period of the last 3 years, the maximum days under water of 248 days is larger, thus worse.

AveDuration:

'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.'

• Compared with the benchmark SPY (41 days) in the period of the last 5 years, the average time in days below previous high water mark of 46 days of Align Technology is greater, thus worse.
• Looking at average time in days below previous high water mark in of 57 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (35 days).
