(Sharecast News) - Wall Street trading got off to a positive start on Tuesday after the index closed out its best August in over 30 years in the previous session and the tech-heavy Nasdaq got off to a strong start on the back of another rally in the sector.
As of 1540 BST, the Dow Jones Industrial Average was up 0.27% at 28,507.34, while the S&P 500 was 0.40% firmer at 3,514.18 and the Nasdaq Composite started out the session 1.06% stronger at 11,900.50.

IHS Markit's final manufacturing PMI also improved in August, expanding to 53.1 from 50.9 in July. However, the reading was slightly weaker than the 53.6 forecast.
Chris Williamson, IHS Markit's chief business economist, said: "The manufacturing upturn gained further ground in August, adding to indications that the third quarter should see a strong rebound in production from the steep decline suffered in the second quarter."
