**Main Description**

The Rotational Momentum Screener Tool allows users to see the hypothetical rankings by month/week/day/quarter of a momentum or relative strength rotation ranking investing strategy. This tool works the same as our Rotation Advanced Tool, but does not perform a backtest, just a ranking output that can be exported to a spreadsheet or viewed on the webpage. This tool is a good way to quickly rank a list of symbols without running a full backtest to either get your monthly trades or just to see how each fund did during an investment period.

## Settings

**Select Data Feed**

Select a data feed to use. The Universal Data Feed has been our default data feed, and provides stock, ETF, and mutual fund data for the US and non-US markets. The Professional Quality Data Feed provides high quality data for US stocks, ETFs, and mutual funds. Additionally there is an option to select historical data, which allows users to select funds with histories that go back as far as 1924.

**Enter Tickers**

Enter an unlimited number of almost any stock, ETF, or mutual fund ticker into Tickers list separating each ticker by a comma. Each ticker entered will be available to choose based on if it’s position score is high enough.

**Start/End Simulation Date**

The date values to start and end the simulation. If a ticker is unavailable for some of the date range entered the default behavior will be to only test the dates when all tickers are available.

**Frequency of Updates**

This setting allows the user to choose how often the conditions are evaluated and updates to allocation are made. For example a monthly update means once a month (at the end of the month), the back tester calculates the new weight values based on each one of the 5 algorithms and adjusts the weightings of each ticker to match the weightings reported by each of the algorithms. These weightings will be held until the end of next month when the back tester will evaluate (ask the question) again and re-weight the portfolio according to the new values for each algorithm.

**Cash Filter**

When a fund falls below a specified moving average you may decide to pull that investment and invest in a cash or bond fund (or any ticker you choose). With the cash filter settings you have the option to turn the cash filter on and off, select the symbol you would like to invest in instead, and select the moving average method and length that will cause the switch to occur. If the box labeled ‘Try The Next Best Selection(s) before going to Cash ETF’ is selected, the next fund will be tried if the top fund is below the moving average before resort to the cash filter fund as a last resort. For example you are invested in a stock market, but the price is below the 200 day moving average, so you may use the cash filter to invest in a short duration bond instead this limiting your risk in a bearish market. If the fund is below either cash filter moving average then the cash filter is active.*Invest in Cash Filter Fund if Cash Fund Outperforms Top X Fund*: If the cash filter fund selected outperforms any of the funds in the list, then invest in the cash filter fund instead of that fund even if it is above the moving average.

**Position Score Calculations**

Position Score is used to determine which funds in your list to invest in. The top scoring funds are chosen each month based on which fund is the strongest. Position score can factor in momentum (relative strength), volatility, downside volatility, sharpe ratio, information ratio, and mean reversion. You may choose 3 time-frames and weightings for each weighting method and use all 4 methods of you choose to arrive at a final position score that will determine what funds to invest in next period.

*Lookback Lengths*

For each of the weighting algorithms the lookback length can be adjusted. This setting will control the number of months the Momentum, Sharpe Ratio, or Information Ratio, or Volatility will be calculated on to determine the fund selected.

*F Factor*

The F factor can be adjusted for the Sharpe Ratio and Information Ratio. This setting allows the user to adjust how important volatility is in the calculation of the Sharpe Ratio and Information Ratio. A setting of 0 means volatility is disregarded, a setting of 1 is the standard way these ratios are calculated, and a setting of more than 1 means the the volatility is becoming more and more important to the calculation.

*Downside Volatility*

Only count downward movements as volatile events, not upward (gaining movements). This is a modification of the standard volatility calculation to make sure we do not penalize funds that are performing well, thus causing a traditional volatility calculation to see up moves as a bad thing.

*Mean Reversion*

Mean Reversion allows users to consider some recent down moves as having a positive effect of position scoring, instead of a negative one. This is often thought of as an attempt to get a discounted price on an already good performing stock fund.

*Calmar Ratio*

The Calmar ratio is the ratio of the returns to the maximum drawdown applied over a specific number of days. This rewards funds that perform well, and have low drawdown, and penalizes bigger drawdowns and lower returns. The length (in days) defines the window over which the return is calculated, and the maximum drawdown is found.

**Settings for Calculating Asset Allocation**

(Only Available in Advanced Rotation Tool)

If you are investing in more than 1 symbol you may decide to use asset allocation to decide how much of each symbol to invest in. The default setting is equal weighting for all symbols, but you may choose to maximize Sharpe Ratio, maximize Information Ratio, minimize Volatility, minimize Variance, and maximize the position score used to determine how much the weighting is for each fund.

*Lookback Lengths*

For each of the weighting algorithms the lookback length can be adjusted. This setting will control the number of months the Sharpe Ratio, or Information Ratio, or Variance, or Volatility will be calculated on to determine the weighting of the funds.

*F Factor*

The F factor can be adjusted for the Sharpe Ratio and Information Ratio. This setting allows the user to adjust how important volatility is in the calculation of the Sharpe Ratio and Information Ratio. A setting of 0 means volatility is disregarded, a setting of 1 is the standard way these ratios are calculated, and a setting of more than 1 means the the volatility is becoming more and more important to the calculation.

*Dampening Allocations*

Dampening Allocations limits the full affect of the weighting algorithm. For example the Sharpe Ratio calculation will often cause allocations to go to 0% if the value is negative for that period, this may be undesirable; a lower dampening ratio will cause the minimum allocation to be >0% so a fund will not be totally absent from your portfolio, the full effects of the Sharpe Ratio will thus be “dampened”. A dampening ratio of 100 means the the dampening is off (the weighting algorithm can operate without interference). A dampening ratio of 0 means the maximum dampening will be applied to the portfolio, at 0 the weightings will not be far from an equally weighted portfolio.
