Calling for pre-market most actives on a day after what happened Thursday is not the easiest task.  Still, there are many movers from the likes of Activision Blizzard, Inc. (NASDAQ: ATVI), American International Group Inc. (NYSE: AIG), Crocs Inc. (NASDAQ: CROX), Federal Signal Corp. (NYSE: FSS), Genoptix, Inc. (NASDAQ: GXDX), Hansen Natural Corporation (NASDAQ: HANS), Las Vegas Sands Corp. (NYSE: LVS), Radian Group Inc. (NYSE: RDN), PMI Group Inc. (NYSE: PMI), Sequenom Inc. (NASDAQ: SQNM), and Trico Marine Services Inc. (NASDAQ: TRMA).  We have included the news, the move, and relative color where applicable.

Activision Blizzard, Inc. (NASDAQ: ATVI) said Q1 profit basically doubled with strong deferred revenues, along with “Call of Duty” and “World of Warcraft” sales.  It also raised its 2010 earnings guidance.  Shares were up over 2% last night and the stock is up 4.3% at $10.94 on almost 50,000 shares.

American International Group Inc. (NYSE: AIG) managed a surprise profit on lower write-downs and on lower restructuring expenses.  AIG also said that earnings grew at most of its core insurance operations. Shares are up 4% at $38.25 on over 150,000 shares.

Crocs Inc. (NASDAQ: CROX) reported a Q1 profit on stronger sales.  Margins grew as well and we have seen at least one positive research call on ity this morning.  Shares were up more than this earlier, but the stock is up 5% at $10.10 on thin trading volume.

Federal Signal Corp. (NYSE: FSS) priced a 10.5 million share secondary offering at $6.25 per share after a $6.46 close.  This $61.7 million raised is less than some $75 million expected.  Shares are down 4.6% at $6.16 on over 50,000 shares.

Genoptix, Inc. (NASDAQ: GXDX) is down 14.5% at $31.00 after a $36.26 close, but volume is thin around 20,000 shares.  Lower than expected earnings are to blame here.

Hansen Natural Corporation (NASDAQ: HANS) is not looking so natural after Q1 profits fell over 20% and under Thomson Reuters estimates after it saw price declines.  Shares are trading down 14% at $36.57 but on very thin trading volume.

Las Vegas Sands Corp. (NYSE: LVS) is after reporting its first real profit in two years, and on very strong revenue to beat Thomson Reuters estimates.  Shares are up 2.5% to $22.20 this morning on over 100,000 shares.

Radian Group Inc. (NYSE: RDN) is up along with PMI Group Inc. (NYSE: PMI) after KBW upgraded both stocks this morning.  Radian is up 2.6% at $10.10 and PMI is up 4.7% at $4.45 this morning.

Sequenom Inc. (NASDAQ: SQNM) is down after earnings with an in-line loss despite higher revenues.  Margins fell over 10% on increased costs.  Auriga remained cautious on this one. Shares are down 8% at $5.15 on relatively thin volume.

Trico Marine Services Inc. (NASDAQ: TRMA) has an appropriate acronym for its ticker.. Trauma… Its Q1 loss was worse than expected and it also said it is looking for ways to improve its financial liquidity and may need the 30-day grace period on an interest payment. Shares are down a whopping 31.5% at $1.67 on about 100,000 shares.

Also, we compiled a huge list of stocks that rose yesterday during the bloodbath.  These are not funds nor ETFs, are not inverse ETFs, most are not in mergers, and the hurdle here was active trading and a 2% gain.
