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.'

Which means for our asset as example:
  • The total return, or increase in value over 5 years of IDEXX Laboratories is 351.2%, which is higher, thus better compared to the benchmark SPY (65.6%) in the same period.
  • During the last 3 years, the total return, or increase in value is 149%, which is larger, thus better than the value of 48.8% from the benchmark.

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.'

Using this definition on our asset we see for example:
  • The annual performance (CAGR) over 5 years of IDEXX Laboratories is 35.2%, which is larger, thus better compared to the benchmark SPY (10.6%) in the same period.
  • During the last 3 years, the compounded annual growth rate (CAGR) is 35.6%, which is larger, thus better than the value of 14.2% from the benchmark.

Volatility:

'In finance, volatility (symbol σ) is the degree of variation of a trading price series over time as measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). Commonly, the higher the volatility, the riskier the security.'

Which means for our asset as example:
  • The volatility over 5 years of IDEXX Laboratories is 28%, which is greater, thus worse compared to the benchmark SPY (13.6%) in the same period.
  • Compared with SPY (12.8%) in the period of the last 3 years, the historical 30 days volatility of 26.6% is larger, thus worse.

DownVol:

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

Which means for our asset as example:
  • The downside deviation over 5 years of IDEXX Laboratories is 30.7%, which is larger, thus worse compared to the benchmark SPY (15%) in the same period.
  • Compared with SPY (14.6%) in the period of the last 3 years, the downside volatility of 29.7% is greater, thus worse.

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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (0.6) in the period of the last 5 years, the risk / return profile (Sharpe) of 1.17 of IDEXX Laboratories is greater, thus better.
  • During the last 3 years, the Sharpe Ratio is 1.25, which is larger, thus better than the value of 0.91 from the benchmark.

Sortino:

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Applying this definition to our asset in some examples:
  • Looking at the excess return divided by the downside deviation of 1.07 in the last 5 years of IDEXX Laboratories, we see it is relatively higher, thus better in comparison to the benchmark SPY (0.54)
  • Compared with SPY (0.8) in the period of the last 3 years, the excess return divided by the downside deviation of 1.12 is greater, thus better.

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.'

Using this definition on our asset we see for example:
  • The Downside risk index over 5 years of IDEXX Laboratories is 10 , which is higher, thus worse compared to the benchmark SPY (4.03 ) in the same period.
  • During the last 3 years, the Ulcer Ratio is 9.48 , which is greater, thus worse than the value of 4.1 from the benchmark.

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.'

Which means for our asset as example:
  • Looking at the maximum drop from peak to valley of -30.8 days in the last 5 years of IDEXX Laboratories, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (-19.3 days)
  • Compared with SPY (-19.3 days) in the period of the last 3 years, the maximum reduction from previous high of -30.8 days is lower, 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.'

Applying this definition to our asset in some examples:
  • 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 larger, thus worse.
  • Looking at maximum time in days below previous high water mark in of 183 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (139 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.'

Applying this definition to our asset in some examples:
  • The average days under water over 5 years of IDEXX Laboratories is 75 days, which is higher, thus worse compared to the benchmark SPY (41 days) in the same period.
  • Compared with SPY (35 days) in the period of the last 3 years, the average days under water of 48 days is larger, thus worse.
