Quantitative Strategy drops almost 500 bux at Morgan Stanley

Oct. 10 (Bloomberg) -- Morgan Stanley, the world's second- biggest securities firm, said its quantitative strategy traders lost $390 million during a single day in August as their computer models failed to account for widespread'' investor selling. The company's traders lost money on 14 days during the quarter ended Aug. 31,with the largest single-day trading loss being $390 million,'' the New York-based firm said in a quarterly regulatory filing today. Morgan Stanley said last month that the quantitative strategies group lost $480 million during the quarter after they were caught off-guard when other investors sold securities to reduce borrowings. The company disclosed today that daily trading losses during the quarter exceeded the firm's trading value-at- risk calculation on six days during the quarter.

said they lost > $100 MM on 6 days for the quarter.

that's pretty steep.

but they made > $100 MM on 18 days during the quarter.

so it's all about balancing your risk
