How to Make Money in Stocks

Overview — in one paragraph

O'Neil's study asked: before the biggest winning stocks doubled and tripled, what did they have in common? The answer became CAN SLIM — seven traits spanning earnings acceleration, newness, institutional sponsorship, and market direction — plus a chart discipline for timing the entry (the cup-with-handle base) and the strictest loss rule in mainstream print: sell, always, at 7–8% down. It's a complete system: what to buy, when to buy it, and when to be wrong.

The framework — what the book actually teaches

• C-A-NEarnings drive big moves. Current quarterly earnings up big (C), annual growth (A), and something New (N — product, management, or price high). The fundamental half lives in earnings & catalysts and fundamentals basics.
• S-L-I-MSupply, Leaders, Institutions, Market. Modest float, leading stocks in leading groups (relative strength), institutional accumulation (volume), and — the trump card — the general market direction (M): three in four stocks follow it.
• BASESBuy strength from proper bases. The cup-with-handle and its cousins are accumulation structures; buy the breakout through the pivot at a new high, never the bargain dip. The playbook: cup-with-handle breakout.
• 7–8%The mechanical stop. Every position, no exceptions, sold at a 7–8% loss — small, survivable wounds that make the occasional 100% winner matter. The math is position sizing and expected value.
• HISTORYStudy historical winners. The book's annotated charts of past super-stocks train pattern recognition on real cases — the same idea behind our stock selection & scanning page.

How traders actually use it

Where it fits on the reading path

The definitive growth/momentum system book. It's Livermore's leaders-and-pivots logic (How to Trade in Stocks) industrialized with data. Weinstein's stage analysis gives the same worldview a simpler map; Minervini's SEPA is its modern refinement. Who it's for: position and swing traders in stocks, especially anyone drawn to growth leaders.

Honest assessment

Strengths: one of the few retail books built on a systematic historical study; complete — selection, timing, risk, and market filter in one method; the loss rule alone has saved fortunes.

Limits: the study is in-sample and pre-decimalization — academic tests of momentum support the broad idea, not the exact recipe; base patterns are partly subjective in real time; and the system demands bull markets — it produces long flat stretches when M is against you. IBD's ratings (the convenient implementation) are a paid product; the concepts here are free.
