The domestic equity benchmarks ended with deep cuts on Thursday, snapping a three-day gaining streak. After opening higher at 17,772.05, the Nifty 50 index declined as the session progressed and hit the day's low of 17,573.60 in late trade. Trading was volatile due to expiry of weekly index options on the NSE. Barring the Nifty Metal index, all the sectoral indices ended in the red. Auto, consumer durables and realty shares were under pressure.
