In this article, we present performance results of a long/short equity trading strategy in weekly timeframe.
Article updated on 07/10/2020
Long/short equity strategies involve taking both long and short positions so that a net profit is made while market exposure is minimized. Usually during bull markets long positions tend to be more profitable than short and the other way around during bear markets. Therefore, the profitability of a long/short strategy does not depend on market direction.
There are many ways of developing and executing these type of strategies. In this article we look at a strategy in the weekly timeframe based on factors (also known as features, predictors or attributes) engineered by DLPAL LS:
DLPAL LS uses primitive attributes of price action, and specifically the open, high, low and close, to extract features types in an unsupervised learning mode based on general feature clusters. Then, the program uses the extracted features in supervised learning mode to identify long and short candidates in a universe of securities. The long/short identification is based on a set of calculated features and the user has flexibility in ranking the results according to their values… Historical files of features can be generated for backtesting the strategies and for machine learning.
The strategy described below is applied to Dow 30 stocks but any other group can be used.
Note: In this strategy up to six positions are open at all times. This strategy is employed in Premium Market Signals.

Universe: Dow 30 stocks (DOW not included and BA not included after 06/12/2020)
