@VinayakSharma, Unfortunately, such massive selling will take beating on all stocks. However, I believe the structure is still intact. 540-550 is a good support zone. Hope this support levels survives on next leg down of Nifty. On the positive side, even though Nifty was down on Friday, SunPharma still saw signs of green.
Note - I think there is a US FDA visit to Halol plant this month. Keep that news in radar.
