Fidelity Investments Says Blunder Limited: The brokerage, which unnerved investors Monday with news of a $2-billion accounting error in its Magellan fund, said the more than 200 other funds it manages are free of similar errors. The mutual funds powerhouse is the second-largest financial services firm in the United States, with more than $400 billion in assets. Its disclosure of the accounting error forced it to scrap year-end payments to shareholders of the venerable Magellan fund once managed by Peter Lynch.
