Newbie - simple pipeline question - screening by industry
Mark Cochran

Getting Started Pipeline

Hello!
how would I use pipeline to screen out everything except for one industry? For example, polymer companies or pharma?
the pipeline tutorials I've found give examples of everything BUT this, it seems.

Thanks!!

Maybe take a look at this post for ideas https://www.quantopian.com/posts/how-can-i-implement-specific-sectors-in-my-pipeline-as-a-filter

The Morningstar industry codes are here https://www.quantopian.com/help/fundamentals#industry-sector

So to filter for a specific industry, create a classifier using the .latest method then create a filter from that.

import quantopian.pipeline.data.morningstar as ms  
drug_companies = ms.asset_classification.morningstar_industry_group_code.latest.element_of([20636])

Thanks!! I really appreciate it. Heres what I eventually did. Works great.

def make_pipeline():
drug_companies = ms.asset_classification.morningstar_industry_group_code.latest.element_of([20636]) 

return Pipeline(  
    columns={  
        'sector_code': Sector(),  
    },  
    screen=(drug_companies)  
)
