WASHINGTON (MarketWatch) -- Barclays, Goldman Sachs and Macroeconomic Advisers all slashed their second-quarter GDP estimates on Wednesday. The biggest drop came from Barclays, which now forecasts 1.5% growth, down from a prior estimate of 2.5%, as trade looks to be a slight drag and slower inventory building looks to have subtracted from growth. Meanwhile, Goldman Sachs cut its estimate to 1.3% from 1.4% after the wholesale inventories data and Macroeconomic Advisers cut its view to 1.2% from 1.4% after the trade data.
