Statistics of iShares Global Healthcare ETF (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:
  • Compared with the benchmark SPY (67.1%) in the period of the last 5 years, the total return of 36.6% of iShares Global Healthcare ETF is lower, thus worse.
  • During the last 3 years, the total return is 38.2%, which is lower, thus worse than the value of 51.3% 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.'

Applying this definition to our asset in some examples:
  • The compounded annual growth rate (CAGR) over 5 years of iShares Global Healthcare ETF is 6.4%, which is lower, thus worse compared to the benchmark SPY (10.8%) in the same period.
  • Looking at compounded annual growth rate (CAGR) in of 11.4% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (14.8%).

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 30 days standard deviation of 13.9% in the last 5 years of iShares Global Healthcare ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (13.5%)
  • Compared with SPY (12.8%) in the period of the last 3 years, the volatility of 12.4% is lower, thus better.

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 iShares Global Healthcare ETF is 14.9%, which is greater, thus worse compared to the benchmark SPY (14.8%) in the same period.
  • Compared with SPY (14.7%) in the period of the last 3 years, the downside deviation of 14.1% is lower, thus better.

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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (0.62) in the period of the last 5 years, the risk / return profile (Sharpe) of 0.28 of iShares Global Healthcare ETF is lower, thus worse.
  • Looking at ratio of return and volatility (Sharpe) in of 0.72 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.96).

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.'

Using this definition on our asset we see for example:
  • The ratio of annual return and downside deviation over 5 years of iShares Global Healthcare ETF is 0.26, which is lower, thus worse compared to the benchmark SPY (0.56) in the same period.
  • Compared with SPY (0.84) in the period of the last 3 years, the downside risk / excess return profile of 0.63 is lower, thus worse.

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.'

Which means for our asset as example:
  • Looking at the Ulcer Index of 7.6 in the last 5 years of iShares Global Healthcare ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (3.99 )
  • Looking at Ulcer Ratio in of 4.42 in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (4.1 ).

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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (-19.3 days) in the period of the last 5 years, the maximum reduction from previous high of -19.6 days of iShares Global Healthcare ETF is smaller, thus worse.
  • Compared with SPY (-19.3 days) in the period of the last 3 years, the maximum drop from peak to valley of -14.5 days is greater, thus better.

MaxDuration:

'The Drawdown Duration is the length of any peak to peak period, or the time between new equity highs. The Max Drawdown Duration is the worst (the maximum/longest) amount of time an investment has seen between peaks (equity highs) in days.'

Which means for our asset as example:
  • The maximum days below previous high over 5 years of iShares Global Healthcare ETF is 472 days, which is higher, thus worse compared to the benchmark SPY (187 days) in the same period.
  • Compared with SPY (139 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 187 days is greater, thus worse.

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:
  • Looking at the average days below previous high of 124 days in the last 5 years of iShares Global Healthcare ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (42 days)
  • During the last 3 years, the average days below previous high is 52 days, which is greater, thus worse than the value of 36 days from the benchmark.
