Bharti at 328 is directly above above several supports, the most critical being 310.
There's nothing wrong on the fundametals here and this appears to be a technical weakness brought on by shorting pressure in derivatives.
There could be some pressure from Reliance Info coming on, but that's not a major deal. Bharti is way ahead in the game.
With 310 as s/l, or even 318, this is likely to be a great price for entry at current levels.
A close above 335 would be an early sign of recovery, and above 245-250 would move strong.
Keep a watch.
