It doesn't take huge volume to move the price, small volume can, too...if a single share isn't traded the rest of the day, the stock still would finish up, without there being "massive" volume. And a look at past days shows large volume can mean the stock moving nowhere, or even slightly down. It just helps to have that volume, because more people are aware of it, and definitely can help the stock move more quickly. But semantics aside, it's going up, that's enough for me!
