A sub-strategy for the U.S. Sector strategy. It looks at momentum using a short lookback period to respond faster to changes in the market.

See the main US Sector strategy for a detailed asset description.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (62.6%) in the period of the last 5 years, the total return, or performance of 142.5% of US sectors short lookback is larger, thus better.
- During the last 3 years, the total return, or performance is 107.4%, which is higher, thus better than the value of 32.1% from the benchmark.

'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.'

Which means for our asset as example:- The annual return (CAGR) over 5 years of US sectors short lookback is 19.4%, which is larger, thus better compared to the benchmark SPY (10.2%) in the same period.
- During the last 3 years, the annual return (CAGR) is 27.5%, which is greater, thus better than the value of 9.7% from the benchmark.

'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.'

Applying this definition to our asset in some examples:- The volatility over 5 years of US sectors short lookback is 25.9%, which is higher, thus worse compared to the benchmark SPY (21.5%) in the same period.
- During the last 3 years, the volatility is 30.8%, which is higher, thus worse than the value of 24.8% from the benchmark.

'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.'

Applying this definition to our asset in some examples:- Looking at the downside deviation of 18.4% in the last 5 years of US sectors short lookback, we see it is relatively larger, thus worse in comparison to the benchmark SPY (15.6%)
- Compared with SPY (17.9%) in the period of the last 3 years, the downside risk of 21.8% is greater, thus worse.

'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 (0.36) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of 0.65 of US sectors short lookback is greater, thus better.
- Looking at Sharpe Ratio in of 0.81 in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (0.29).

'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.'

Which means for our asset as example:- The ratio of annual return and downside deviation over 5 years of US sectors short lookback is 0.92, which is higher, thus better compared to the benchmark SPY (0.5) in the same period.
- During the last 3 years, the ratio of annual return and downside deviation is 1.15, which is greater, thus better than the value of 0.4 from the benchmark.

'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:- Compared with the benchmark SPY (8.52 ) in the period of the last 5 years, the Downside risk index of 8.96 of US sectors short lookback is higher, thus worse.
- Compared with SPY (10 ) in the period of the last 3 years, the Ulcer Index of 10 is greater, thus worse.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum reduction from previous high of -37.3 days of US sectors short lookback is lower, thus worse.
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum reduction from previous high of -37.3 days is lower, thus worse.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (235 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 147 days of US sectors short lookback is smaller, thus better.
- During the last 3 years, the maximum days below previous high is 127 days, which is lower, thus better than the value of 235 days from the benchmark.

'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:- The average days below previous high over 5 years of US sectors short lookback is 45 days, which is smaller, thus better compared to the benchmark SPY (55 days) in the same period.
- During the last 3 years, the average days under water is 34 days, which is smaller, thus better than the value of 59 days from the benchmark.
