Sensex gains 100 points, Nifty hovers around 8,750 on positive global cues

Snapping two-session long losing spree, the S&P BSE Sensex on Tuesday rallied over 100 points, while the broader Nifty50 tested its key 8,750 level.

The headline indices rallied after Asian markets turned positive as investors seemed to award the first US presidential debate to Democrat Hillary Clinton over Republican Donald Trump.

At 09:30 am, the 30-share index was trading at 28,377, up 82.88 points, while broad-based 50-share index was quoting 8,747, up 24.90 points.

"Now, its a matter of time that the Nifty would slide below the recent support level of 8,688 to test 8,640-8,600 levels. On the upside, 8,750-8,790 would be seen as strong resistance levels," said Angel Broking in a research note.

Power Grid stock was the top Sensex gainer and added over 1 per cent on the BSE.

Among Asian markets, China's Shanghai Composite was trading flat, Hong Kong's Hang Seng gained over 100 points, while Japan's Nikkei added 0.32 per cent.
