Volume is the daily number of shares of a security that are traded. Volume is one of the most important indicators we watch. Its relation with price movements tells us 90% of the story behind a stock?s movement and future movements. At its simplest, increased volume on increasing prices shows accumulation. Increased volume on lower prices shows distribution. There are many variations on this theme, and we spend a great deal of time poring over price/volume relations to determine which way a stock will move.
