Volume: Is anyone backing the move?
How to read the volume bars on a stock chart, why breakouts on heavy volume are stronger, and why rallies on thin volume often fade.
Volume tells you how many people agree
Volume is the number of shares traded in a day, shown as the bars along the bottom of the chart. Price tells you where the stock went. Volume tells you how much conviction was behind it.
What to look for
- A rise on heavy volume: many buyers agree. The move is more likely to last.
- A rise on thin volume: few buyers. The move can fade quickly.
- Compare today’s bar with the last few weeks, not with other stocks.
Big funds can’t hide their buying. When they step in, volume jumps, which is why volume often moves before price does.
Today the stock closed at its highest price in a month, on nearly three times its usual volume. What does the volume add?
- Many traders backed the move, so it is more likely to hold
- Nothing. Only price matters
- High volume means the stock is about to fall
Show the answer
Many traders backed the move, so it is more likely to hold. Volume is participation. A new high that many traders bought into is harder to knock back than one that happened while nobody was paying attention.
Volume confirms the breakout
The first push higher came on thin volume and faded. The second came with heavy volume, broke above the old high and kept going. Same chart, same price area, a different crowd behind it.
Volume on breakouts matters most. A breakout on low volume is one of the easiest traps for beginners.
