NEW YORK, May 22 (Reuters) - U.S. stocks fell for a fourth day on Friday on persistent worries about the U.S. budget deficit, with U.S. Treasuries and the dollar losing ground.

Shares of big manufacturers such as Caterpillar Inc (CAT.N: Quote, Profile, Research), down 3.5 percent at $34.31, and financials such as Bank of America (BAC.N: Quote, Profile, Research), down 3 percent at $11.07, led the decline. Investors have reduced positions in U.S. assets due to concerns about the country's debt.

However, multinationals and commodity companies limited the major U.S. stock indexes' losses as investors bought stocks in sectors that could benefit from the weaker dollar.
