What's Ken Griffin Of Citadel Buying and Selling?

. 4 min read

Citadel Advisors just released their quarterly 13F filing with the SEC. Here's what the Billionaire hedge fund manager has been up to.

Citadel Advisors Latest Form 13F Filing

On February 9th, 2018, Ken Griffin's firm Citadel Advisors filed their quarterly Form 13F regulatory filing. I reviewed the 13F filing to review holdings in Citadel Advisors' large portfolio.

The hedge fund's stock portfolio totals $154.4 billion according to the latest filing. The list value of stock holdings is up 18.5% when compared to the last quarter. As a benchmark, the S&P 500 was up 6.1% over the same period. Not bad!

Quarter-over-Quarter Turnover (QoQ Turnover) measures the level of trading activity in a portfolio. Citadel Advisors's QoQ Turnover for the latest quarter was 33.5%, so the firm appears to trade a significant percent of its portfolio each quarter.

Citadel Advisors's Recent Price Pull-Back Stocks

To find stocks in his portfolio that may be unpopular at the moment and trading at cheap valuations, I ranked his holdings by price pullbacks. The ranking table below lists the stocks in Citadel Advisors’ portfolio by stock price performance over the last 30 days.

OGEN ORAGENICS INC $18.56 $2.20 -88.1%

Managers with more than $100 million in qualifying assets under management are required to disclose their holdings to the SEC each quarter via 13F filings. Qualifying assets include long positions in U.S. equities and ADRs, call/put options, and convertible debt securities. Shorts, cash positions, foreign investments and other assets are not included. It is important to note that these filings are due 45 days after the quarter end date. Therefore, Citadel Advisors' holdings above represent positions held as of December 31st and not necessarily reflective of the fund's current stock holdings.

However, most can agree that with thousands of stocks traded on U.S. exchanges, doing thorough research on each one is nearly impossible for smaller investors. Leveraging the resources of the largest hedge funds on Wall Street can be a powerful way to narrow down the list.
