Align Technology (ALGN)

TotalReturn:

'The total return on a portfolio of investments takes into account not only the capital appreciation on the portfolio, but also the income received on the portfolio. The income typically consists of interest, dividends, and securities lending fees. This contrasts with the price return, which takes into account only the capital gain on an investment.'

• The total return, or increase in value over 5 years of Align Technology is 540.7%, which is greater, thus better compared to the benchmark SPY (67.9%) in the same period.
• Compared with SPY (46.6%) in the period of the last 3 years, the total return, or increase in value of 319.1% is larger, thus better.

CAGR:

'The compound annual growth rate (CAGR) is a useful measure of growth over multiple time periods. It can be thought of as the growth rate that gets you from the initial investment value to the ending investment value if you assume that the investment has been compounding over the time period.'

• Compared with the benchmark SPY (10.9%) in the period of the last 5 years, the annual return (CAGR) of 45% of Align Technology is larger, thus better.
• Looking at annual performance (CAGR) in of 61.2% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (13.6%).

Volatility:

'Volatility is a rate at which the price of a security increases or decreases for a given set of returns. Volatility is measured by calculating the standard deviation of the annualized returns over a given period of time. It shows the range to which the price of a security may increase or decrease. Volatility measures the risk of a security. It is used in option pricing formula to gauge the fluctuations in the returns of the underlying assets. Volatility indicates the pricing behavior of the security and helps estimate the fluctuations that may happen in a short period of time.'

• Looking at the historical 30 days volatility of 35.1% in the last 5 years of Align Technology, we see it is relatively greater, thus worse in comparison to the benchmark SPY (13.3%)
• Compared with SPY (12.5%) in the period of the last 3 years, the 30 days standard deviation of 38% is greater, thus worse.

DownVol:

'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 volatility over 5 years of Align Technology is 38.6%, which is greater, thus worse compared to the benchmark SPY (14.6%) in the same period.
• During the last 3 years, the downside deviation is 43.4%, which is higher, thus worse than the value of 14.2% 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.'

• Compared with the benchmark SPY (0.64) in the period of the last 5 years, the Sharpe Ratio of 1.21 of Align Technology is higher, thus better.
• Looking at Sharpe Ratio in of 1.55 in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (0.89).

Sortino:

'The Sortino ratio improves upon the Sharpe ratio by isolating downside volatility from total volatility by dividing excess return by the downside deviation. The Sortino ratio is a variation of the Sharpe ratio that differentiates harmful volatility from total overall volatility by using the asset's standard deviation of negative asset returns, called downside deviation. The Sortino ratio takes the asset's return and subtracts the risk-free rate, and then divides that amount by the asset's downside deviation. The ratio was named after Frank A. Sortino.'

• Looking at the downside risk / excess return profile of 1.1 in the last 5 years of Align Technology, we see it is relatively greater, thus better in comparison to the benchmark SPY (0.58)
• During the last 3 years, the excess return divided by the downside deviation is 1.35, which is greater, thus better than the value of 0.78 from the benchmark.

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.'

• Looking at the Ulcer Index of 14 in the last 5 years of Align Technology, we see it is relatively larger, thus better in comparison to the benchmark SPY (3.96 )
• During the last 3 years, the Ulcer Index is 17 , which is greater, thus better than the value of 4.01 from the benchmark.

MaxDD:

'Maximum drawdown measures the loss in any losing period during a fund’s investment record. It is defined as the percent retrenchment from a fund’s peak value to the fund’s valley value. The drawdown is in effect from the time the fund’s retrenchment begins until a new fund high is reached. The maximum drawdown encompasses both the period from the fund’s peak to the fund’s valley (length), and the time from the fund’s valley to a new fund high (recovery). It measures the largest percentage drawdown that has occurred in any fund’s data record.'

• Compared with the benchmark SPY (-19.3 days) in the period of the last 5 years, the maximum reduction from previous high of -53 days of Align Technology is smaller, thus worse.
• Looking at maximum DrawDown in of -53 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-19.3 days).

MaxDuration:

'The Maximum 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. It is the length of time the account was in the Max Drawdown. A Max Drawdown measures a retrenchment from when an equity curve reaches a new high. It’s the maximum an account lost during that retrenchment. This method is applied because a valley can’t be measured until a new high occurs. Once the new high is reached, the percentage change from the old high to the bottom of the largest trough is recorded.'

• The maximum days below previous high over 5 years of Align Technology is 161 days, which is lower, thus better compared to the benchmark SPY (187 days) in the same period.
• During the last 3 years, the maximum days below previous high is 161 days, which is higher, thus worse than the value of 139 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.'

• Compared with the benchmark SPY (41 days) in the period of the last 5 years, the average days under water of 34 days of Align Technology is smaller, thus better.
• Looking at average days under water in of 32 days in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (36 days).
