General speaking we view price up and volume increase, and price down volume drop is normal. What observe that price drop but volume increased is another story. Is it a PDTB? Maybe Yes. Last week we expect the price might drop back to 47.31. Therefore, when price drop down lower than 47.31, we watch the price will go lower to around 45.30. Price test 2 time around this level, and was unable to drop it down. Then we think it might be a push down to buy by major player. Considering about this, we reenter our long position again. We set our stop loss around 300 MA.
