The US markets ended mostly in green on Tuesday amid continued optimism about an end to the record-setting U.S. government shutdown, following the senate’s 60-40 vote in favour of a temporary funding bill, which would also reverse some of the recent mass federal layoffs. However, traders express some uncertainty about the near-term outlook for the markets - especially the possibility of a tech bubble - following recent volatility. Meanwhile, the NASDAQ came under selling pressure weighed by 3.1 percent slump in shares of Nvidia (NVDA) after Softbank sold its entire stake in the chipmaker for more than $5 billion.

On the sectoral front, pharmaceutical stocks saw significant strength on the day, with the NYSE Arca Pharmaceutical Index surging by 2.4 percent. Besides, a sharp increase by the price of crude oil has contributed to considerable strength among energy stocks, which are moving higher along with biotechnology and healthcare stocks.

Dow Jones Industrial Average jumped 559.33 points or 1.18 percent to 47,927.96 and S&P 500 rose 14.18 points or 0.21 percent to 6,846.61, while Nasdaq slumped 58.87 points or 0.25 percent to 23,468.30.
