Technical analysis

Stage 3 (Extended)

Stage 3 (Extended) is when a stock's price continues climbing well after an initial breakout, showing sustained upward momentum over weeks or months. You'll see this term in technical analysis—the study of price charts and patterns—where traders divide stock movements into four stages to spot buying and selling opportunities. Stage 3 matters because it's often the longest and most profitable phase for investors who got in early, though it can also be risky if you're buying near the end. For example, if TechCorp broke out of a consolidation pattern in January and kept rising through March, that extended run would be Stage 3. The key sign: higher highs and higher lows on the chart, showing consistent buyer interest.
