Competitors, analysts, journalists, and more all just got their quarterly peek inside the stock portfolios of the biggest fund managers in the world.
Secretive funds like Chase Coleman's Tiger Global revealed the changes they made to their holdings in the third quarter, and some of the biggest names were very active.
Billionaire Carl Icahn sold off some of his third-biggest holding, Occidental Petroleum, which is currently trading at a low for the year, filings showed on Thursday. Stanley Druckenmiller's family office ditched almost all of its Uber stake, selling more than 2 million shares in the quarter.
Continue reading below to see some of the biggest moves from the biggest managers.
Druckenmiller dumps Uber
The most recent headline of a prominent investor dumping the ride-sharing giant came from company founder Travis Kalanick selling more than $700 million-worth of stock.
But billionaire fund manager Stanley Druckenmiller actually sold a majority of his stake before Kalanick made his move.
Filings show that Druckenmiller's family office owned just under 2.7 million shares, worth roughly $125 million, at the end of the second quarter. The latest filings show that he now owns only 166,882 shares, which the firm valued at roughly $5.1 million.
Druckenmiller also sold more than a million shares of Microsoft, which is his family office's biggest holding, and half of his Alibaba stake, which was worth $175 million at the end of the second quarter.
Tiger Global is a fan of Alibaba
Billionaire Tiger Cub Chase Coleman is known for his tech prowess, and made a big bet on Alibaba, which has seen its stock price bounce up and down all year.
The fund nearly doubled its stake in the Chinese company in the third quarter, buying more than 3 million shares. Its stake was worth $1.3 billion at the end of the third quarter and was its fifth-biggest holding.
The firm continued to add to its large Facebook stake in the quarter as well, buying more than 2 million shares.
Paul Tudor Jones' Allergan bet
After surviving the activism of one billionaire fund manager, Allergan was an attractive investment for another in the third quarter.
David Tepper tried to force the drugmaker to split the CEO and chairman role for more than a year, and the company announced it would explore that when current CEO and chairman Brent Saunders left the position. Now, Paul Tudor Jones has piled into the stock, which has struggled in recent years.
Tudor Jones nearly doubled his stake in the drugmaker, and owned just under $95 million worth of stock in the company at the end of the third quarter.
D1's Sundheim still loves Netflix
Former Viking Global investment chief Daniel Sundheim told conference-goers in May that he loved Netflix. His portfolio shows he walked the walk.
Sundheim, who runs the nearly $8 billion D1 Capital, added a million more Netflix shares in the third quarter. His total stake was worth $988 million at the end of the third quarter.
He also plowed in Amazon, roughly sextupling his stake, from 66,500 shares at the end of the second quarter to more than 411,000 shares.
Icahn chipping away at his Occidental Petroleum stake
Billionaire investor Carl Icahn shed a chunk of one of his biggest holdings in the third quarter.
Occidental Petroleum, which is now trading at the lowest price it has all year, made up 7% of Icahn's multi-billion-dollar portfolio at the end of the second quarter, filings show, but he dumped more than 7 million shares of the energy company in the third quarter.
His stake was worth $1.1 billion, as of the end of the third quarter.
