Top Day Trader Alerts (ACE, BIDU, BP, CPTS, LWSN, MSG, NANO, SCSC)

Many stocks are on the move for day traders and active traders when you consider this is a summer Friday and earnings season is not yet started.  Today’s top alerts are in ACE Limited (NYSE: ACE), Baidu, Inc. (NASDAQ: BIDU), Google Inc. (NASDAQ: GOOG), BP plc (NYSE: BP), Conceptus, Inc. (NASDAQ: CPTS), Lawson Software, Inc. (NASDAQ: LWSN), Madison Square Garden, Inc. (NASDAQ: MSG), Nanometrics Incorporated (NASDAQ: NANO), and ScanSource, Inc. (NASDAQ: SCSC).

ACE Limited (NYSE: ACE) will replace Millipore in the S&P 500 Index.  With a $17.7 billion market cap, this one will be a decent ‘must buy’ stock for index funds that now have to buy the stock whether they wanted to or not.  Shares were up almost 5% last night and the move this morning is 5.3% at $54.99 on well over 100,000 shares.

Baidu, Inc. (NASDAQ: BIDU) is getting shelled after Google Inc. (NASDAQ: GOOG) announced that China renewed its license despite the fights between the two. -5.2% at $68.61 on over 700,000 shares; Google shares are up 3.8% just under $474.00 on over 100,000 shares in the pre-market.

BP plc (NYSE: BP) is down 2.2% at $33.00 this morning on reports that Gulf of Mexico forecast conditions may hamper the cleanup efforts and on word that it has denied claims that it will be able to stop the leak faster than planned.

Conceptus, Inc. (NASDAQ: CPTS) was down as much as 30% last night on a bad earnings warning before getting down about 25% before the night hours went out.  This morning shares are down ‘only’ 22% now at $12.30 on about 400,000 shares.

Lawson Software, Inc. (NASDAQ: LWSN) was down about 3.5% last night after guidance was under expectations. Shares are down 6.4% at $7.13, but there has only been a small handful of trades.

Madison Square Garden, Inc. (NASDAQ: MSG) is down over 4% at $19.51 as LeBron James went to the Miami Heat.  The silly thing about this drop is that the stock is now lower than it was even before LeBron was rumored as considering the Knicks under MSG.  Almost a silly drop considering that shares were at $20.10 to $20.25 before the real hype or hope got started and considering the market has headed up 3 straight days.

Nanometrics Incorporated (NASDAQ: NANO) reaffirmed its 2010 and 2011 goals last night after the Oppenheimer downgrade took out 20% for a $8.69 close.  Shares are up 7% at $9.30 on almost 50,000 shares in the pre-market.

ScanSource, Inc. (NASDAQ: SCSC) raised sales guidance last night and shares were up over 6% last night. Shares are up over 6% at $26.61 on thin volume.
