The reason why stocks are going up on a day when outflows are greater than outflows is because of the way in which inflows and outflows are counted.

The inflow and outflow of funds is based on the transaction details. The details show that buying is an inflow, showing that selling is an outflow. But the transaction details of the inside of the display of the buy and sell is not necessarily correct, the transaction details are by period of statistics, and then according to the last transaction of the period is to buy or sell to determine.

For example, a time period transaction details show 10 dollars to buy 3000 hands, but the real may be sold 9.9 sold 2999 hands, finally someone 10 dollars to buy a hand.

So the stock market value of the rise and fall is not entirely by the inflow and outflow of funds to determine the amount of its market value is by a variety of factors **** with the role of the formation.
