Using blpapi and xbbg to pull member holdings and weight data from Bloomberg?

Question

Beginner Python user here. I was wondering if anyone has had any success using blpapi and xbbg to pull member holdings and constituent weight data directly into Python from Bloomberg (eg from a portfolio or ETF or index). I have a BBG license, of course.

Thank you in advance to any suggestions! Any advice is much appreciated!

Answer 1

This is how you get it in Excel:

=BDS("SPX Index","INDX_MWEIGHT")

The python equivalent should work

Answer 2

To add on to what ytoledano said you can do the below to get index constituents:

from xbbg import blp
index = "SPCPGN Index"
index_constituents = blp.bds(index,"INDX_MWEIGHT")
print(index_constituents)
