My concern is that - like any other portfolio optimization algorithm - blindly optimizing on fundamentals and short term returns will lead to investing in firms who just dump external costs onto people in the present and future; so, screening with sustainability criteria is important to me.
I might start implementing some of these but would love for someone else to add a few PRs as well. The code is pretty modular especially if we want to add new strategies.
Does the code have any factor investing features at all right now? I was just reading about alpha lens, another project focused on performance attribution of factors. To avoid reinventing the wheel, are there any other libraries that can be leveraged to add factors - so portfolios are constructed to go long and/or short a certain factor like sustainability or etc.

Is it possible to factor (e.g. GRI) sustainability criteria into the portfolio fitness function? https://news.ycombinator.com/item?id=21922558

This is perfect. Thank you for sharing this.

(Sustainable) Index ETFs in the stocks.txt universe would likely be less sensitive to single performers' effects in unbalanced portfolios.

I will try to modify it such that it's easy to add factors. Thanks for sharing this.
