“I don’t use volume very often. The only really good use for volume is to identify washouts. It’s the main thing it helps you with. You know, you’ll always hear people say, “Oh, the market went up, up, up on light volume.
That’s all it ever does. That’s called a melt-up. That’s what markets do — they generally have lighter volume on the upside and heavier volume on the downside.
It’s what investing is all about. You get lighter volume on the upside because buying is a process — it’s slower and takes more consideration, so it doesn’t happen all at once. Selling is quite the opposite — it usually happens all at once because something is scaring investors.
It’s an emotional response. It doesn’t take a lot of time; you’re scared, so you sell. So, there’s almost always greater volume on the downside.
