The SEC requires that investment managers with more than $100 million in assets file a 13-F form, disclosing their holdings each quarter. Here’s how you can use it to invest like your favorite famous investors.
For many investors, they may not find out what influential investors bought until they see it on a financial news site such as CNBC:

You may be wondering how CNBC finds this information, or how you can find this information for other big name investors.
If investors meet the SEC’s criteria for assets and holdings, they are required to file 13F forms with the SEC each quarter. So, every 3 months investors can get a fresh look at the holdings of the most influential investors.
In the article above, we can see that the big news was Buffett adding Starz company stock to his portfolio. Specifically, he bought 5.62 million shares of the media company. Where can you find that information?
