Major U.S. stock-indexes are little changed on Tuesday, following three straight sessions of losses, on growing speculation that the Federal Reserve could raise interest rates as soon as September. Concerns about a rate hike pushed the blue-chip Dow index slipped into negative territory for 2015 on Monday, while the S&P 500 and Nasdaq touched their lowest levels in over a month. Data on Monday showed U.S. small business confidence rose to a five-month high in May, with owners expecting a solid improvement in profits, which bodes well for the economy's prospects in the months ahead.
