Stock indexes drifted to a mixed finish on Wall Street Thursday, as some heavyweight technology and communications sector stocks offset gains elsewhere in the market. The S&P 500 fell less than 0.1% after spending the day wavering between small gains and losses.

Wall Street is making history in more ways than one. This has been nothing short of a banner year for Wall Street. Whereas the stock market has historically delivered average annual gains of around 10%,

The S&P 500 climbed 0.7% in morning trading after erasing an initial drop. The Dow Jones Industrial Average was up 311 points, or 0.7%, as of 10:40 a.m. Eastern time, while the Nasdaq composite gained 0.7%.
