Understanding the ‘C’ in CAN SLIM: Analyzing Current Quarterly Earnings Growth – William J. O’Neil

Understanding the ‘C’ in CAN SLIM: Analyzing Current Quarterly Earnings Growth – William J. O’Neil is the vital first step for any investor following the Mastering the CAN SLIM System: A Comprehensive Guide to William J. O’Neil’s How to Make Money in Stocks. According to O’Neil’s extensive historical research, the “C” stands for Current Quarterly Earnings Per Share (EPS), and it represents the single most important element in picking winning stocks. Before a stock makes a massive price advancement, it almost always displays a significant percentage increase in its most recent quarterly earnings compared to the same quarter of the previous year.

The Core Requirements for Current Quarterly Earnings

To successfully apply the O’Neil methodology, you must look beyond simple profitability. William J. O’Neil insisted that the “C” component requires a minimum earnings increase of 25% to 50%. However, the truly legendary performers often show increases of 100%, 200%, or even more. When analyzing these figures, it is essential to compare the current quarter with the same quarter from one year ago to account for seasonality in business cycles.

Practical application involves more than just a single high-growth quarter. Investors should look for earnings acceleration. If a company reports 20% growth two quarters ago, 35% growth last quarter, and 60% growth this quarter, the trend suggests the company is entering its “sweet spot.” This acceleration is often a precursor to a stock becoming a Leader or Laggard in its industry group.

Beyond EPS: The Role of Sales and Margins

Earnings per share can sometimes be manipulated through accounting maneuvers or stock buybacks. To ensure the “C” is of high quality, O’Neil suggests verifying that earnings are supported by quarterly sales growth of at least 25%. Increasing sales indicate that the company’s products or services are in high demand, often driven by the Identifying New Products and Management: The ‘N’ Factor.

Additionally, expanding profit margins are a bullish sign. If a company is increasing its earnings at a faster rate than its sales, it usually means the business is becoming more efficient or has significant pricing power. This fundamental strength often attracts Institutional Sponsorship, which provides the “big money” necessary to drive the stock price significantly higher.

Practical Examples and Case Studies

Understanding the “C” is best illustrated through historical stock market winners that met these stringent criteria before their parabolic moves:

• Google (Alphabet) in 2004: Shortly after its IPO, Google reported quarterly earnings increases of over 100%. This massive “C” factor, combined with a revolutionary search product, propelled the stock to heights many thought impossible at the time.
• NVIDIA (NVDA) in 2023: As the AI revolution took hold, NVIDIA reported quarterly earnings growth exceeding 400% in certain periods. This explosive acceleration in the “C” component made it a textbook CAN SLIM winner, far outpacing the broader market.
• Cisco Systems in 1990: During the early stages of the internet build-out, Cisco consistently reported quarterly EPS gains of 100% or more. This fundamental strength was a primary reason it became one of the greatest performers of the decade.

Common Pitfalls in Analyzing Current Earnings

Investors often make the mistake of buying stocks with low P/E ratios rather than high earnings growth. O’Neil’s research debunked the myth that low P/E stocks are “safer.” Instead, he found that the greatest winners often trade at high P/E ratios precisely because their earnings growth is so exceptional. To avoid Common Mistakes to Avoid When Trading the O’Neil Way, never ignore a stock just because it looks “expensive” on a valuation basis if the quarterly earnings growth is accelerating.

Furthermore, always exclude one-time, non-recurring gains. If a company shows a 100% increase in earnings due to the sale of a factory or a legal settlement, that is not a true “C” factor. The growth must come from the company’s core operations to be sustainable.

Conclusion

Analyzing current quarterly earnings growth is the cornerstone of the CAN SLIM philosophy. By focusing on companies that demonstrate a minimum of 25% EPS growth—and ideally, accelerating sales and margins—you align yourself with the strongest businesses in the market. While the “C” is just one part of the puzzle, it provides the fundamental fuel that powers price breakouts.

Frequently Asked Questions

What is the minimum quarterly earnings growth required in CAN SLIM?
William J. O’Neil recommends looking for a minimum increase of 25% to 50% compared to the same quarter in the previous year. The biggest winners often show growth of 100% or more before their major runs.

Should I ignore stocks with a high P/E ratio if the “C” is strong?
Yes, O’Neil found that the P/E ratio is not a reliable indicator of a stock’s potential. Exceptional quarterly growth often leads to high P/E ratios, but these stocks can still double or triple in price.

How do sales growth and profit margins relate to the “C”?
Strong quarterly EPS should be supported by sales growth of at least 25%. Expanding profit margins further confirm that the earnings growth is high-quality and sustainable.

What is “earnings acceleration” and why is it important?
Acceleration occurs when the percentage of earnings growth increases sequentially (e.g., 20%, then 40%, then 80%). This indicates a business is gaining momentum and is a hallmark of “Super Stocks.”

Can a stock be a CAN SLIM winner without strong current earnings?
It is very rare. O’Neil’s study of the greatest market winners showed that 3 out of 4 had significant quarterly earnings gains before they began their massive price advances.

Why do I compare the current quarter to the same quarter a year ago?
This comparison eliminates seasonal variations. For example, retailers always have higher earnings in Q4; comparing Q4 to Q3 would be misleading, whereas comparing Q4 this year to Q4 last year reveals true growth.

How do modern screening tools help in identifying the “C”?
Modern tools allow investors to filter thousands of stocks instantly for 25%+ EPS growth, sales acceleration, and margin expansion, making the manual analysis described in O’Neil’s original books much more efficient.
