RE: Vol up.. good or bad? This is my opinion. When volume goes up and the closing price also goes up, tht means it is good for the stock. However if the volume is up but the sp is down this is a bad sign for the stock. For every trade there is a buyer and a seller. If the s p goes up , it means there are more buyer willing to pay a higher price. Most often in the stock market there are some insiders who know about something and we do't known. Something is very important to notice, Insiders are few in numbers. If only a few people keep on buying and the selling side is of big number, you can be sure that there is something good going on. Or, if the seling side is done by a few people then something is bad happening in the stock.
Just check the number of stock brokers in the buying side and the selling side you should be able to figure out yourself. For exsample I notice the buying side comes from No, 74 and 7, but the seeling side involves more than 10 different brokers I knew only a few insiders know some good news and that is why they are buying heavily from many know nothing shareholders.
