WASHINGTON (MarketWatch) -- The Philadelphia Fed's manufacturing index rebounded to a reading of 9.0 in March from a negative 6.3 reading in February, well above a MarketWatch-compiled economist forecast of 3.5. The increase retraces almost all of the sharp fall in February, suggesting that the dampening impact of severe winter weather will not be long-lasting. The index stood at 9.4 in January.
