Shares in India dropped 370 points, or 0.5%, to 81,630 in morning trade on Friday, as traders remained cautious ahead of US Fed Chair Jerome Powell's speech at the Jackson Hole Economic Symposium. The BSE Sensex halted a six-day winning streak that had been supported by optimism over Goods and Services Tax (GST) reforms. The broader index pulled back from its near four-week high reached the previous day, tracking an overnight decline on Wall Street amid ongoing tech stock sell-offs and anticipation of Powell's remarks. Almost all sectors traded in the red, led by financial services (-0.9%), followed by banking (-0.8%), metals (-0.7%), tech (-0.6%), and oil & gas (-0.5%). Among the biggest laggards were HCL Tech (-1.4%), HDFC Bank (-1.5%), Asian Paints (-1.5%), JSW Steel (-1.3%), and ITC (-1.3%). For the week, the index is still on track for a 1.3% rise, which would mark the second consecutive weekly gain, buoyed by optimism over GST reforms.
