Statistics (YTD)

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

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (104.5%) in the period of the last 5 years, the total return, or performance of 111.4% of Intuitive Surgical is greater, thus better.
  • Looking at total return in of 111.4% in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (57.9%).

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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (15.4%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of 16.2% of Intuitive Surgical is higher, thus better.
  • During the last 3 years, the compounded annual growth rate (CAGR) is 28.5%, which is larger, thus better than the value of 16.5% 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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (17.5%) in the period of the last 5 years, the historical 30 days volatility of 32.9% of Intuitive Surgical is greater, thus worse.
  • Compared with SPY (17.2%) in the period of the last 3 years, the 30 days standard deviation of 31.8% 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:
  • Looking at the downside volatility of 22.6% in the last 5 years of Intuitive Surgical, we see it is relatively greater, thus worse in comparison to the benchmark SPY (12.1%)
  • Compared with SPY (11.5%) in the period of the last 3 years, the downside volatility of 20% is greater, 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.'

Using this definition on our asset we see for example:
  • The ratio of return and volatility (Sharpe) over 5 years of Intuitive Surgical is 0.42, which is lower, thus worse compared to the benchmark SPY (0.74) in the same period.
  • Compared with SPY (0.81) in the period of the last 3 years, the risk / return profile (Sharpe) of 0.82 is higher, thus better.

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.'

Using this definition on our asset we see for example:
  • The excess return divided by the downside deviation over 5 years of Intuitive Surgical is 0.61, which is lower, thus worse compared to the benchmark SPY (1.07) in the same period.
  • During the last 3 years, the ratio of annual return and downside deviation is 1.3, which is larger, thus better than the value of 1.22 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.'

Applying this definition to our asset in some examples:
  • The Downside risk index over 5 years of Intuitive Surgical is 19 , which is greater, thus worse compared to the benchmark SPY (8.48 ) in the same period.
  • Compared with SPY (5.3 ) in the period of the last 3 years, the Downside risk index of 11 is greater, 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.'

Which means for our asset as example:
  • The maximum drop from peak to valley over 5 years of Intuitive Surgical is -49.9 days, which is lower, thus worse compared to the benchmark SPY (-24.5 days) in the same period.
  • Compared with SPY (-18.8 days) in the period of the last 3 years, the maximum drop from peak to valley of -27.2 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.'

Which means for our asset as example:
  • The maximum days below previous high over 5 years of Intuitive Surgical is 549 days, which is higher, thus worse compared to the benchmark SPY (488 days) in the same period.
  • Compared with SPY (199 days) in the period of the last 3 years, the maximum days below previous high of 132 days is smaller, thus better.

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.'

Using this definition on our asset we see for example:
  • Looking at the average days below previous high of 146 days in the last 5 years of Intuitive Surgical, we see it is relatively higher, thus worse in comparison to the benchmark SPY (120 days)
  • Compared with SPY (47 days) in the period of the last 3 years, the average days below previous high of 37 days is lower, thus better.
