Intuitive Surgical (ISRG)

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.'

• Looking at the total return, or increase in value of 290.8% in the last 5 years of Intuitive Surgical, we see it is relatively higher, thus better in comparison to the benchmark SPY (66.2%)
• During the last 3 years, the total return is 132.4%, which is higher, thus better than the value of 47.5% from the benchmark.

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 annual return (CAGR) of 31.4% in the last 5 years of Intuitive Surgical, we see it is relatively higher, thus better in comparison to the benchmark SPY (10.7%)
• During the last 3 years, the compounded annual growth rate (CAGR) is 32.6%, which is greater, thus better than the value of 13.9% 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.'

• Compared with the benchmark SPY (13.3%) in the period of the last 5 years, the volatility of 26.1% of Intuitive Surgical is larger, thus worse.
• Looking at volatility in of 26.4% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (12.5%).

DownVol:

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

• The downside deviation over 5 years of Intuitive Surgical is 26.6%, which is larger, thus worse compared to the benchmark SPY (14.6%) in the same period.
• Looking at downside risk in of 29.4% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (14.2%).

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.'

• The risk / return profile (Sharpe) over 5 years of Intuitive Surgical is 1.11, which is larger, thus better compared to the benchmark SPY (0.62) in the same period.
• During the last 3 years, the risk / return profile (Sharpe) is 1.14, which is higher, 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.'

• The downside risk / excess return profile over 5 years of Intuitive Surgical is 1.08, which is larger, thus better compared to the benchmark SPY (0.56) in the same period.
• During the last 3 years, the ratio of annual return and downside deviation is 1.02, which is higher, thus better than the value of 0.8 from the benchmark.

Ulcer:

'The Ulcer Index is a technical indicator that measures downside risk, in terms of both the depth and duration of price declines. The index increases in value as the price moves farther away from a recent high and falls as the price rises to new highs. The indicator is usually calculated over a 14-day period, with the Ulcer Index showing the percentage drawdown a trader can expect from the high over that period. The greater the value of the Ulcer Index, the longer it takes for a stock to get back to the former high.'

• Looking at the Ulcer Ratio of 6.65 in the last 5 years of Intuitive Surgical, we see it is relatively higher, thus better in comparison to the benchmark SPY (3.96 )
• Compared with SPY (4.01 ) in the period of the last 3 years, the Ulcer Index of 6.66 is higher, thus better.

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.'

• The maximum drop from peak to valley over 5 years of Intuitive Surgical is -24.3 days, which is lower, thus worse compared to the benchmark SPY (-19.3 days) in the same period.
• Looking at maximum drop from peak to valley in of -24.3 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.'

• Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum days below previous high of 121 days of Intuitive Surgical is smaller, thus better.
• Compared with SPY (139 days) in the period of the last 3 years, the maximum days under water of 116 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.'

• Compared with the benchmark SPY (41 days) in the period of the last 5 years, the average days below previous high of 27 days of Intuitive Surgical is smaller, thus better.
• Looking at average time in days below previous high water mark in of 26 days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (36 days).
