Cup and handle

Bases: where big moves are prepared

Most strong advances in stocks don't start out of nowhere. Before a breakout, price usually spends weeks or months moving sideways in a base — a consolidation in which sellers from the previous high are gradually absorbed and new buyers quietly accumulate shares. William O'Neil popularised these bases (cup with handle, flat base and others) in his CAN SLIM approach; Mark Minervini later described the volatility contraction pattern (VCP). You don't need any system to use the core ideas: a tight base, drying-up volume and a breakout above a clear level (the pivot) on rising volume.

This lesson covers the cup and handle in depth first, then the rounding bottom, the flat base and the VCP.

Cup and handle

Anatomy

1. A prior uptrend. The cup and handle is a continuation pattern; it should come after a meaningful advance (O'Neil wanted at least ~30%).
2. Left rim — the high where the correction starts: $100.
3. Cup — a rounded decline and recovery, not a sharp V. Here the bottom is $82, a depth of 18%. A commonly cited guideline is roughly 12–35% depth; deeper cups fail more often.
4. Right rim — price returns to around the left rim: $100 again.
5. Handle — a small, quiet pullback just below the right rim: here down to $95 (−5%). The handle shakes out the last weak holders before the breakout.
6. Pivot — the handle's high, $100. A close above it on volume is the buy signal.

Why the rounded shape matters

A V-shaped bottom means price snapped back fast — the sellers who bought at $100 are still sitting there, and the stock runs into a wall of supply at the rim. A rounded cup takes time: weak holders sell on the way down, the bottom is quiet (look at the low volume around $82–84), and the stock gradually moves into the hands of patient buyers. By the time price is back at $100, much of the overhead supply is gone.

Handle rules

• It forms in the upper half of the cup: here the midpoint is ($100 + $82) ÷ 2 = $91, and the handle's low of $95 is well above it.
• Shallow: typically no deeper than ~10–12%. A deep handle means sellers are still strong.
• Drifts down or sideways, not up — it's a shakeout, not a new rally.
• Volume dries up in the handle. Note the shortest bars on the whole chart.
• Usually at least 5 candles on a daily chart (a week or more).

Volume

Volume draws a cup of its own: heavy as price falls from the left rim, lightest at the bottom, rising on the right side, quiet again in the handle, then a spike on the breakout — ideally at least 40–50% above average (a common screening rule). This is where relative volume helps.
