William O'Neil's "How to Make Money in Stocks" (ISBN 9780070480179) remains a cornerstone for investors seeking a systematic, rules-based approach to the markets. This guide translates his time-tested methodology into actionable steps, helping readers build discipline and improve their decision-making.
The following breakdown organizes key elements of O'Neil's strategy into clear, scannable sections, enabling you to quickly reference the most relevant concepts for your investment journey.
| Concept | Definition | Purpose | Key Indicator |
|---|---|---|---|
| CAN SLIM | A comprehensive framework for selecting stocks based on fundamentals and momentum. | Identifies stocks with strong growth potential and clear buy points. | Acronym: Current Earnings, Annual Growth, New Products, Supply/Demand, Leader/Laggard, Institutional Sponsorship, Market Direction. |
| Market Direction | Assessing the overall health and trend of the broader market. | Avoids buying during downtrends and aligns trades with the prevailing market. | Use a broad market index like the S&P 500 to determine if it's in a confirmed uptrend. |
| Stock Selection | The process of filtering thousands of stocks to find high-probability opportunities. | Focuses capital on the most promising names instead of spreading it too thin. | Apply CAN SLIM to rank and select stocks that meet strict criteria. |
| Buy Points | Specific price levels where a stock shows signs of strong institutional accumulation. | Enters at a calculated moment to maximize upside potential and manage risk. | Defined by chart patterns such as a flat base, cup with handle, or breakout above consolidation. |
Understanding the CAN SLIM System
At the heart of O'Neil's method is the CAN SLIM acronym, which serves as a checklist for evaluating stocks before committing capital. Each letter represents a specific criterion that helps filter for quality and momentum, reducing emotional decision-making.
C is for Current Quarterly Earnings
Look for companies reporting strong current earnings per share, preferably up at least 25% compared to the same quarter last year. This demonstrates recent acceleration rather than slow, steady growth.
A is for Annual Earnings Growth
Examine earnings per share growth over the past three years. Consistent double-digit annual growth signals a company with durable competitive advantages and scalable business model.

Applying O'Neil's system requires more than theory; it demands a structured routine of research, monitoring, and disciplined execution. Successful investors treat stock selection like a profession rather than a gamble.
Stage 1: Market Assessment
Before picking individual stocks, confirm that the overall market is in a confirmed uptrend. Use major indices and avoid fighting the broader market direction, as this dramatically increases the probability of success.
Stage 2: Build a Watchlist
Screen for stocks meeting most of the CAN SLIM criteria, then track their price action and volume patterns. This pre-screening saves time and focuses attention on names ready for action.
Mastering Buy Points and Exit Rules
O'Neil emphasizes waiting for clear technical signals rather than guessing at valuations. A well-defined entry point, combined with predefined sell rules, protects capital and lets winners run.
Identifying High-Quality Breakouts
Look for stocks breaking out above a flat base or cup with handle pattern on above-average volume. This confluence of price action and volume suggests institutional investors are actively accumulating shares.
Setting Stop-Loss Levels
Protect your downside by placing sell stops just below key support levels, such as the 7%-8% maximum decline from your purchase price. This prevents small losses from turning into devastating mistakes.

FAQ
Reader questions
How do I identify a stock's proper buy point using O'Neil's method?
Focus on stocks breaking out of a proper base with volume at least 20% above average, and confirm the breakout aligns with a strong market direction.
What should I do if a stock I bought using CAN SLIM starts to decline?
Check the stop-loss level you set at purchase; if the decline reaches that point, exit quickly to limit losses and preserve capital for the next opportunity.
Can I apply CAN SLIM to growth stocks in any sector?
Yes, but prioritize sectors currently leading the market and favor companies with clear new products, strong earnings growth, and visible institutional sponsorship. Review weekly, paying close attention to earnings releases, industry trends, and volume spikes that may signal a new buy point or the need to exit a position.
