Statistics of IDEXX Laboratories (YTD)

What do these metrics mean? [Read More] [Hide]

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.'

Applying this definition to our asset in some examples:
  • Looking at the total return of 290.9% in the last 5 years of IDEXX Laboratories, we see it is relatively greater, thus better in comparison to the benchmark SPY (68.7%)
  • Looking at total return, or performance in of 180.2% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (47.9%).

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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (11%) in the period of the last 5 years, the annual performance (CAGR) of 31.4% of IDEXX Laboratories is greater, thus better.
  • Compared with SPY (14%) in the period of the last 3 years, the annual performance (CAGR) of 41.1% is larger, thus better.

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.'

Applying this definition to our asset in some examples:
  • Looking at the volatility of 27.4% in the last 5 years of IDEXX Laboratories, we see it is relatively larger, thus worse in comparison to the benchmark SPY (13.3%)
  • Compared with SPY (12.5%) in the period of the last 3 years, the historical 30 days volatility of 26.9% is higher, 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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (14.6%) in the period of the last 5 years, the downside volatility of 29.4% of IDEXX Laboratories is higher, thus worse.
  • During the last 3 years, the downside deviation is 28.5%, which is higher, thus worse than the value of 14.2% from the benchmark.

Sharpe:

'The Sharpe ratio is the measure of risk-adjusted return of a financial portfolio. Sharpe ratio is a measure of excess portfolio return over the risk-free rate relative to its standard deviation. Normally, the 90-day Treasury bill rate is taken as the proxy for risk-free rate. A portfolio with a higher Sharpe ratio is considered superior relative to its peers. The measure was named after William F Sharpe, a Nobel laureate and professor of finance, emeritus at Stanford University.'

Which means for our asset as example:
  • The ratio of return and volatility (Sharpe) over 5 years of IDEXX Laboratories is 1.06, which is larger, thus better compared to the benchmark SPY (0.64) in the same period.
  • During the last 3 years, the risk / return profile (Sharpe) is 1.44, which is greater, thus better than the value of 0.91 from the benchmark.

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.'

Applying this definition to our asset in some examples:
  • Looking at the downside risk / excess return profile of 0.98 in the last 5 years of IDEXX Laboratories, we see it is relatively higher, thus better in comparison to the benchmark SPY (0.58)
  • Compared with SPY (0.81) in the period of the last 3 years, the ratio of annual return and downside deviation of 1.36 is greater, thus better.

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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (3.96 ) in the period of the last 5 years, the Downside risk index of 11 of IDEXX Laboratories is larger, thus better.
  • Compared with SPY (4.01 ) in the period of the last 3 years, the Ulcer Index of 9.43 is greater, thus better.

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (-19.3 days) in the period of the last 5 years, the maximum drop from peak to valley of -30.8 days of IDEXX Laboratories is lower, thus worse.
  • Compared with SPY (-19.3 days) in the period of the last 3 years, the maximum DrawDown of -30.8 days is smaller, thus worse.

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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum days under water of 318 days of IDEXX Laboratories is higher, thus worse.
  • Compared with SPY (139 days) in the period of the last 3 years, the maximum days under water of 181 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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (41 days) in the period of the last 5 years, the average days below previous high of 76 days of IDEXX Laboratories is higher, thus worse.
  • Looking at average days under water in of 47 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (36 days).
