Module 20: The Fuel of the Market - Volume Analysis
If price is the car, Volume is the fuel. A car can roll downhill without fuel (a weak price drop), but it needs immense fuel to climb a mountain (a strong uptrend). Volume analysis distinguishes between a genuine institutional market shift and a temporary retail "hiccup".
1. What is Volume?
Volume is the total number of shares transacted during a specific time period. On technical charts, it appears as a vertical histogram.
2. The Four Golden Rules of Volume
To deploy volume effectively, rely on these foundational relationships:
- Price Rising + Volume Rising: Strong Bullish Trend. High conviction from institutional buyers.
- Price Rising + Volume Falling: Weak Rally. The trend is "running on fumes" and may imminently reverse.
- Price Falling + Volume Rising: Strong Bearish Trend. Widespread panic and aggressive institutional liquidation.
- Price Falling + Volume Falling: Weak Sell-off. Buyers are temporarily sidelined; no real panic exists.
3. Confirming Breakouts
A genuine breakout requires price to cross resistance alongside trading volume that is 2x–3x the average of the last 10 days, proving "Big Money" is entering the trade. A "Fakeout" occurs when price crosses resistance but volume remains flat, signaling retail exhaustion.
Case Study: Bearish Divergence Professional analysts utilize indicators like the Volume Price Trend (VPT) to identify Divergence.
- Analysis: If a stock price achieves a "Higher High," but trading volume generates a "Lower High," you have Bearish Divergence. This is a massive structural red flag—the price is rising artificially, but fewer institutional players are participating. A sharp crash is highly probable.
