Yeah, I know StockOperator98 understands this much better than I do but it is still a mystery to me how, as rjalexand says, 90% volume is based on 3 trades. If Microsoft had 60 million shares trade in 3 trades (90% of average), I think it would be on the news. While maybe it isn't too relative to MSFT, it somehow looks like 'borrowing from Peter to pay Peter (instead of Paul).'
