The three major US stock market indexes closed mixed on Tuesday as investors digested a slew of economic data and awaited the Federal Reserve's latest policy decision. The Dow Jones Industrial Average rose 0.2%, the S&P 500 gained 0.1%, while the Nasdaq Composite Index fell 0.1%. The mixed performance came as investors weighed a better-than-expected reading on consumer confidence against a weaker-than-expected report on durable goods orders. The Conference Board's consumer confidence index rose to 108.3 in February, surpassing economists' expectations of 102.0. However, the Commerce Department reported that orders for durable goods, excluding transportation, fell 4.5% in January, below the expected decline of 3.5%. All in all, investors are now looking ahead to the Federal Reserve's policy decision on Wednesday. The central bank is widely expected to raise interest rates by 25 basis points and provide guidance on the future path of monetary policy.
