gorilla gap in saregama prices

13 April 2011 closing price 79.35
15th 87.1 with High at 91.4
great increase in volume
in spite of sensex fall
not seen in BSE bulk deals.

any explanation for a poor scrip to jump like this.

either news based or operator driven:

price run up on this stock has happened earlier as well.

good news:
price close above 100MA
trading range broken on the upside.
nearest resistance is far off, giving good risk reward to anyone going long at current levels.

chart attached.

Maybe operator driven, to push the price above the averages and bring about the MA crossovers..
