UBS trading pains
UBS
(NYSE: UBS) is under scrutiny after one of its traders, Kweku Adoboli, allegedly raked up $2 billion in losses through illegal trades. According to The Wall Street Journal, Adoboli confessed he had done the trades. Risk-control officers discovered the loss on Wednesday and began questioning Adoboli, who later left to go home. From there he sent an email to managers admitting he had done the trades. Adoboli was then arrested by the London police. In addition to the regular 24 hours, authorities have been granted a 12-hour extension for how long they can detain Adoboli. No charges have been made against the rogue trader.

UBS feels the pressure of the loss considering it had overhauled its risk management system after losing $50 billion in securities three years ago. Investors had given the bank a hard time after its near collapse in the 2008 financial crisis. Read more at The Wall Street Journal.

Research In Motion
's (Nasdaq: RIMM) investors were disappointed for the third quarter in a row.

The company's tablet, the Playbook, was out-shipped by the iPad 46-1 in the last quarter.

But RIM is hoping its new generation of BlackBerry phones -- the first in a year -- will take market share from both Apple and other companies using Google's (Nasdaq: GOOG) Android operating platform. The company will also release new software for the Playbook that will bring an email function to the tablet and allow many of the Android applications. Read more at Bloomberg.
