Stop Loss: 280 would be a strong support line. Its the gapup opening in Mid July that is still unfilled. Price has already taken support twice at that level. Any fall below that level could spell a short term downtrend.
Any bounce after a fall to the 280 levels should be used for accumulation.
Strategy: Its a Longterm Investment bet. One could ride the wave by buying and selling partially within the channel to reduce the cost of buying. Fall below 280 Levels will invalidate this strategy
