What Is a Breakout (and Why Volume Matters)
A breakout occurs when a stock's price moves above a resistance level — typically a prior high, a consolidation pattern, or a psychological round number. The expectation is that once resistance clears, the stock can move freely higher.
The problem: Many "breakouts" fail. The stock pokes above resistance, attracts chasing buyers, then reverses hard. This is called a failed breakout or shakeout.
Volume is the solution: A breakout on low volume means few participants are driving the move — it can easily reverse. A breakout on heavy volume (50%+ above average or more) signals:
- Institutional buying — funds are accumulating
- High conviction — participants are paying up at new prices
- Supply absorbed — sellers at the resistance level have been overwhelmed
The rule: Price tells you what; volume tells you why. This screen requires both: price near highs (what) AND volume surge (why).
