Help with Bloomberg function please!

Hi, I am running into a problem and I wanted to see if the experts online could help me! The problem: I want to see top ownership of AAPL. Let's say Fidelity manages portfolios with AAPL in it and one of the Fidelity portfolios is owned by CALPERS (big pension fund). I want the results to return CALPERS because they are the end owner of the stock not Fidelity. If anyone has any insights into how I can do this in Bloomberg, it would be super helpful. Thank you! submitted by /u/Test15151515 [link]
