There are several stocks trading more heavily than usual this morning, and also experiencing large gains or drops in share prices. These include Oracle Corp. (NASDAQ: ORCL), Teradata Corp. (NYSE: TDC), Commercefirst Bancorp Inc. (NASDAQ: CMFB), China Ming Yang Wind Power Group Ltd. (NYSE: MY), and Research in Motion Ltd. (NASDAQ: RIMM).

After the first half hour of trading this morning, Oracle is down nearly -13% at $25.42. Volume is heavy, with 22.3 million shares already traded, compared with a daily average of 31 million. The business software company reported weak earnings after markets closed last night. See more coverage here.

Teradata is down more than -12.5% at $44.15. Volume is heavy, with nearly half the average daily volume of 1.9 million shares already traded this morning. The data warehousing software maker’s stock was downgraded from ‘outperform’ to ‘perform’ at Oppenheimer.

Commercefirst is up more than 80% at $6.24. Volume is 4x the daily average, but trading in this stock is always very light. The Maryland bank holding company is being acquired by Sandy Spring Bancorp Inc. (NASDAQ: SASR) for $24.5 million in stock and cash, or about $13.50/share.

China Ming Yang Wind Power is up more than 15% at $1.58. Volume is already greater than the daily average of about 230,000 shares traded. The Chinese wind turbine maker has announced that it will continue share and ADS repurchases under its $50 million buyback program.

Research in Motion is up about 7.5% at $13.46. Volume has already nearly equaled the daily average of 22 million shares traded. The smartphone maker is getting a boost on reports that at least two offers for the company did not materialize. Apparently this is interpreted to mean that RIM is under consideration as a takeover target — and that’s good news for shareholders.
