Steve Cohen's SAC Capital Boosts Positions in MedAssets & OCZ Technology

Steve Cohen's hedge fund SAC Capital just filed two 13G's with the SEC detailing its latest portfolio activity.

MedAssets (MDAS)

Per the first filing, SAC Capital has disclosed a 5.6% ownership stake in MedAssets (MDAS) with 3,238,369 shares. This marks an increase of 10,814% in their position size since the end of 2011 as they only held a tiny position then. The new disclosure was made due to trading activity on April 5th.

SAC isn't the only big-name hedge fund involved in this stock, either. We recently also detailed Senator Investment Group's stake in MedAssets as well.

Per Google Finance, MedAssets "provides technology-enabled products and services. The Company’s technology-enabled solutions are delivered primarily through company-hosted software, or software as a service (SaaS) or Web-based applications, supported by implementation, consulting and outsourced services and consulting, as well as enterprise-wide sales and customer management and support."


OCZ Technology (OCZ)

Cohen's firm also filed a 13G on OCZ where they revealed a 5.5% ownership stake in the company with 3,711,431 shares. This marks a 71% increase in their position size since the end of 2011.

We originally detailed when SAC built its OCZ stake back in the summer of last year. Their latest disclosure was due to trading activity on April 5th.

Per Google Finance, OCZ is "a provider of high performance solid state drives (SSDs) and memory modules for computing devices and systems. In addition to its SSD and Memory Module product lines, the Company also designs, develops, manufactures and distributes other high performance components for computing devices and systems, including thermal management solutions and alternating current/direct current (AC/DC) switching power supply units (PSUs)."

Steven Cohen's SAC Capital Builds OCZ Technology (OCZ) Stake

In a 13G filed with the SEC, Steven Cohen's prominent hedge fund SAC Capital disclosed an updated position in OCZ Technology Group, Inc (OCZ). Due to trading on May 26th, 2011, SAC has revealed a 5.1% ownership position in OCZ with 2,623,346 shares.

This is a massive increase in the hedge fund's position size as they only owned a measly 9,784 shares at the end of the first quarter.

Stock Down 30% Past 1.5 Months

OCZ traded down over 8% yesterday. Since the middle of April, shares are down over 30%. This is at least partially attributable to a negative research report published by Copperfield Research on April 20th, 2011. Also worth noting: over 24% of the float is short.

Our pal & trader @firstadopter on Twitter has been all over this saga. He rebutted the Copperfield report and then laid out why OCZ could be worth $28 per share based on rival Fusio-io's impending IPO. OCZ provides solid state drives (SSDs) and memory modules for computers and other systems.

Shares of OCZ have seen heightened volatility as of late, so it will be interesting to see how it trades after receiving a vote of confidence from SAC Capital.
