Backed by comprehensive backtesting, the article offers concrete evidence of its potential to enhance your investment ideas, empowering you to make informed decisions.

In the following steps we describe the filters of the portfolio stock selection.

Strategy Filters

The "Combined Momentum" strategy employs a set of filters to identify stocks that demonstrate favorable growth prospects while filtering out those that do not meet the criteria. These filters ensure a systematic and disciplined approach to stock selection, increasing the likelihood of identifying stocks with strong momentum. The following screenshot shows the portfolio's filter.

Applied Portfolio Filters

Filter 1: Piotroski F-Score (Quarterly)

The first filter, the Piotroski F-Score (Quarterly), assesses a company's financial strength and overall health. Stocks are considered if their quarterly Piotroski F-Score is greater than the first quantile of all companies.

Filter 2: Growth Rate (over 2 Quarters) of SMA of Closing Price

The second filter evaluates the growth rate of the Simple Moving Average (SMA) of the closing price over a two-quarter period. Stocks with a growth rate exceeding the third quantile of all companies meet this criterion.

Filter 3: Growth Rate (over 1 Year) of SMA of Closing Price

The third filter analyses the growth rate of the SMA of the closing price over a one-year period. Only stocks with a growth rate higher than the third quantile of all companies pass this filter.

Filter 4: Growth Rate (over 1 Quarter) of SMA of Closing Price

The final filter examines the growth rate of the SMA of the closing price over a one-quarter period. Stocks displaying a growth rate greater than the third quantile of all companies meet this requirement.
