Sensex crashes over 600 points today as crude tops $100
On September 24, the Sensex fell more than 600 points and the Nifty slipped below 23,250 intraday as crude oil crossed $100 per barrel, compounding the drag from US 10-year Treasury yields that hit 19-year highs. Navbharat Times reported that by 9:24 am, only 5 of the Sensex's 30 stocks were in the green while 25 were in the red. GIFT Nifty signalled a weak start before the open.
Wednesday's rebound: Sensex up 299 pts, metals led

FII selling persists, DIIs counterbalance

The Times of India asks the结构性 question of who is right — FIIs exiting for safer global yields or DIIs absorbing the supply.
