The cup and handle is a bullish continuation pattern: a rounded, U-shaped base (the "cup") followed by a smaller, tighter pullback (the "handle"), before price breaks out above the cup's rim. It reflects a stock digesting a prior advance, then resuming it.
How it forms
The cup is a gradual, orderly decline and recovery — not a sharp V, but a rounded base where sellers slowly exhaust and buyers slowly return. The handle is a modest, low-volume pullback near the highs as weak hands take profits. When price breaks above the rim on expanding volume, the pattern "completes" and the prior uptrend is expected to resume.
Why the handle matters
The handle is the quality check. A shallow, tight handle on declining volume shows only minor profit-taking — healthy. A deep, sloppy handle that gives back much of the cup suggests real distribution, and the pattern often fails. The handle should drift, not collapse.
The breakout is the headline, but the handle is where you find out if the pattern is real.
The skeptic's caveat
Like all chart patterns, cup and handle is easy to spot in hindsight and partly self-fulfilling — enough traders watch the rim that orders cluster there. It works best aligned with the broader trend and confirmed by a volume-backed breakout, not anticipated inside the handle. A pattern is a hypothesis; the volume and structure are the evidence.
