Should I use equal weight or something more complex like equal risk contribution? We need to load the data and filter out the data frame to just focus on US-listed companies. I estimate that the large relative negative performance compared to the Equal Weight portfolio is due to the high concentration of the Factor portfolios. We need to prepare the dates, variables, and data frames required to use the for loop. Introduction to Portfolio Construction and Analysis with Python is one of the four courses which is part of Investment Management with Python and Machine Learning in Coursera.

The next chart below leverages the cumulative columns which you created: 'Cum Invst', 'Cum SP Returns', 'Cum Ticker Returns', and 'Cum Ticker ROI Mult'. The portfolio in the python code is built up in a bottom up fashion. constraints = ({‘type’: ‘eq’, ‘fun’: lambda x: np.sum(x) — 1}) The above constraint is saying that sum of x should be equal to 1. The annualized return is 13.3% and the annualized risk is 21.7% Updated 6 days ago. I was curious about how to go about building a multi-factor portfolio, and there was a lot written on the concepts but little on the nuts and bolts of the coding aspect. Winsorize_Threshold = .025 #used to determine the winsorize level. Out of Sample will be all the data after that.

Slice the data to look at the initial date quarter and the associated trailing twelve-month fundamental data, Create the Value Factor, Quality Factor, Shareholder Yield Factor, and Low Volatility Factor scores using their respective Z score to normalize the results, Take the equities with fundamental data and then create their respective Trend and Momentum Factor scores. You also have the option to opt-out of these cookies. The following simply gets the risk free rate from the Kenneth French data library and then computes specific risk and return measures.
