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 of 98.7% in the last 5 years of Align Technology, we see it is relatively higher, thus better in comparison to the benchmark SPY (78.4%)
• Looking at total return, or increase in value in of -14% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (44.1%).

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.'

• Looking at the compounded annual growth rate (CAGR) of 14.7% in the last 5 years of Align Technology, we see it is relatively higher, thus better in comparison to the benchmark SPY (12.3%)
• During the last 3 years, the annual performance (CAGR) is -4.9%, which is smaller, thus worse than the value of 12.9% 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 volatility over 5 years of Align Technology is 51.4%, which is higher, thus worse compared to the benchmark SPY (19.9%) in the same period.
• Compared with SPY (23.1%) in the period of the last 3 years, the volatility of 56.3% is larger, 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 (14.6%) in the period of the last 5 years, the downside volatility of 35.2% of Align Technology is larger, thus worse.
• Compared with SPY (16.9%) in the period of the last 3 years, the downside deviation of 37.8% is higher, thus worse.

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.'

• Looking at the ratio of return and volatility (Sharpe) of 0.24 in the last 5 years of Align Technology, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.49)
• Looking at Sharpe Ratio in of -0.13 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.45).

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 (0.67) in the period of the last 5 years, the ratio of annual return and downside deviation of 0.35 of Align Technology is lower, thus worse.
• During the last 3 years, the downside risk / excess return profile is -0.2, which is smaller, thus worse than the value of 0.62 from the benchmark.

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 (6.16 ) in the period of the last 5 years, the Downside risk index of 27 of Align Technology is higher, thus worse.
• Compared with SPY (6.87 ) in the period of the last 3 years, the Ulcer Ratio of 24 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 reduction from previous high over 5 years of Align Technology is -65 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
• During the last 3 years, the maximum DrawDown is -64.9 days, which is lower, thus worse than the value of -33.7 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). 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 (139 days) in the period of the last 5 years, the maximum days below previous high of 522 days of Align Technology is higher, thus worse.
• Looking at maximum days under water in of 291 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (119 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.'

• The average time in days below previous high water mark over 5 years of Align Technology is 139 days, which is larger, thus worse compared to the benchmark SPY (35 days) in the same period.
• Compared with SPY (27 days) in the period of the last 3 years, the average time in days below previous high water mark of 86 days is greater, thus worse.
