Indian shares dropped for a fourth straight session to trade near two-week lows as the BSE Sensex crashed below the 27,000-level ahead of the monthly derivative contracts expiry and as the US Federal Reserve hinted at a possible interest rate hike in December. “Markets opened the day absolutely flat over Wednesday’s closing levels and remained sideways in Thursday's session as well amidst lack of market cues,” said Achin Goel, Head of Wealth Management.
