Is there convenient way to find stocks that track investment performance of certain individuals? Like for example, if I want to track performance of Warren Buffett's investments I would follow Berkshire Hathaway stock (either class A or B) and in general I can get tracking that's "good enough".
Now, let's say I want to do same thing for David Tepper or Carl Icahn... how would I proceed to find stocks that track their performance? I don't necessarily want to track those two (because from what I understand David Tepper runs private fund so he doesn't have stock that tracks him the way BRK tracks Buffett) — I was just using them as an example.
If there is no definite website/page to help with this, how should I start compiling the list (like 1. Warren Buffett - BRK, 2. Carl Icahn - ??)?
EDIT: I've posted comment on only answer, but to prevent similar responses, I'm including what I wrote here in question also. Most important:
I am not looking to recreate or mimic Buffett's portfolio. I will just buy BRK.B.
But I don't want to invest 100% of my money into BRK.B. I want to spread it to other investors that are more into sectors I value. So, how do I proceed with finding stocks that "track" performance of other well known investors like how BRK.B "tracks" Buffett's performance?
