The main US stock indexes finished the session in positive territory

Major US stock indices rose slightly on Tuesday, recording the third sessional increase in a row, helped by the growth of shares in the services sector.

Meanwhile, investors are cautious and look forward to data on the consumer price index and retail sales, which will come out on Wednesday, and may affect the yield of bonds and cause strong movements in the stock market.

A slight influence on the course of new york trading was provided by the National Federation of Independent Business (NFIB), which showed that the small business optimism index rose two points to 106.9 in January. The closely monitored sentiment index among small business owners soared up in January after the December fall. The result was stronger than the forecast at 105.5 points according to a survey of economists from Econoday.

Most components of the DOW index recorded a rise (17 out of 30). Leader of growth were shares of Walmart Inc. (WMT, + 1.54%). Outsider shares were DowDuPont Inc. (DWDP, -1.38%).

Almost all sectors of the S & P index finished trading in positive territory. The services sector grew most (+ 0.7%). The decline was shown only by the conglomerate sector (-0.1%).

At closing:

Dow + 0.16% 24.640.45 +39.18

Nasdaq + 0.45% 7.013.51 +31.55
