HD Supply Holdings Up on Narrower Loss

The top gainer at midday this Tuesday is HD Supply Holdings Inc (NASDAQ:HDS), an industrial distributor in North America, up +8.75%. The company reported today that its losses for the fourth quarter narrowed in comparison to the last quarter of 2012. HDS is in the portfolio of David Tepper.

Secondly is International Tower Hill Mines Ltd (NYSEMKT:THM), up +8.02%. Already a veteran in our reports, it is still up on the heels of its year-end report and analysis. THM is up +113.77% YTD and is part of the holdings of John Paulson.

And third is TAL Education Group (ADR) (NYSE:XRS), up 5.13%. There are currently no reports for XRS but the jump is certainly a boost of confidence for holders Tiger Global and Richard Chilton.

Himax Technologies share downgraded

Topping our loser’s list is Himax Technologies, Inc. (ADR) (NASDAQ:HIMX), down -13.53%. The shares of Himax are being hurt by today’s announcement of a downgrade from BofA Merrill Lynch. HIMX represents almost 9% of Tiger Global’s portfolio.

Second is Idenix Pharmaceuticals Inc (NASDAQ:IDIX), down -4.91%. The Seth Klarman asset and producer of treatments for viral diseases has reported that it will be doing presentations on several new products in April, but did not ease investors’ anxiety over their results.

Last but not least is PennyMac Financial Services Inc (NYSE:PFSI), down -4.41%. This Leon Cooperman pick has just announced the commencement of an underwritten secondary public offering of Class A common stock, which will likely dilute the stakes of other holders.
