Thursday trading session in the U.S. stock market was quite volatile. Indices dynamically changed in the range from minus one to one percent and closed with a small increase of about 0.6 percent. Market participants were closing short positions because of apparent oversold markets, however there were sales in a number of sectors from participants aspiring to reduce risks on their portfolios while waiting for negative macroeconomic data. The Financial and Health sectors looked the clear favorites of the trades.
