Ken Griffin

Billionaire Ken Griffin’s Citadel Investment Group has filed its latest 13F with the SEC, revealing a U.S equity portfolio worth $103.8 billion for the reporting period of September 30. Citadel has been very busy during the third quarter, with the fund opening new positions in over 110 stocks. Furthermore, the investor increased its positions in more than 3,700 companies, while reducing its holdings in more than 4,000 companies. Mr. Griffin is a self-made billionaire and Citadel, which he founded in November 1990, is now is one of the largest funds in the world. Citadel’s main funds are Kensington and Wellington and these funds returned almost 25% in 2012 and 19.4% in 2013. In this article, we are going to take a look at Citadel’s top holdings, in terms of value, following the third quarter.


We pay attention to hedge funds’ moves because our research has shown that hedge funds are extremely talented at picking stocks on the long side of their portfolios. It is true that hedge fund investors have been underperforming the market in recent years. However, this was mainly because hedge funds’ short stock picks lost a ton of money during the bull market that started in March 2009. Hedge fund investors also paid an arm and a leg for the services that they received. We have been tracking the performance of hedge funds’ 15 most popular small-cap stock picks in real time since the end of August 2012. These stocks have returned 102% since then and outperformed the S&P 500 Index by around 53 percentage points (see the details here). That’s why we believe it is important to pay attention to hedge fund sentiment; we also don’t like paying huge fees.
