how can you call it aggressive buying when 50 million shares change hands and price hasnt really moved. Aggressive buying in my mind would be accompanied by buyers wanting the stock more than sellers are willing to sell it down. In the case of SDL to me it seems that there are just as many larger holders wishing to sell the stock down as there are buyers wanting to buy, yes i hear all the stuff about DB and so on but feel there is far more to the current situation than most people are assuming.
