FIIs were sellers of Indian stock futures for a fourth consecutive day on Friday, totalling 10.2 billion rupees, as per regulatory and exchange data, while they sold cash shares on Thursday, snapping a 32-day buying streak. They were buyers of $2.65 million on Friday.

The partially convertible rupee closed at 62.50/51 per dollar compared to 62.87/88 on Friday. The unit moved in a 62.44 to 62.70 range during the session.
Three traders said dollar inflows included those tied to Mylan Inc's purchase of a unit of Strides Arcolab Ltd. . The deal was valued at around $1.6 billion when announced in February.
