Big banks defeat antitrust lawsuit in US over bond trades

1. A federal judge dismissed an antitrust lawsuit against major banks, including BAC. 2. Investors accused banks of manipulating 'odd-lot' corporate bond trades since 2006. 3. Judge found no evidence of a conspiracy to inflate bond prices. 4. Case dismissal is with prejudice and cannot be retried. 5. BAC's market position remains unaffected by this antitrust ruling.
