We start by covering the CANSLIM methodology, but you can jump directly to the 5-step implementation guide.

The CANSLIM Strategy

CANSLIM is a stock investing growth strategy designed by William J. O’Neil to produce market-beating profit performance. The strategy involves investing in companies with high earnings growth, new products, and good institutional sponsorship and buying only in bull markets.

Vital criteria are Current Earnings, Annual Earnings, New Products, Supply, Leaders, Institutional Sponsorship, and Market Direction.

CAN SLIM has the following stock selection criteria:

  • C – Current Earnings
  • A – Annual Earnings
  • N – New Products or Management
  • S – Supply and Demand
  • L – Leaders
  • – Institutional Ownership
  • M – Market Direction

Pioneered by William J. O’Neil, the CANSLIM method is the basis for his classic investing book, “How to Make Money in Stocks.”

Many believe the CANSLIM methodology is a Value Investing strategy, but this is incorrect. The system criteria do not target finding undervalued stocks but instead find companies with fast-growing earnings in growing markets with a competitive advantage. So, CANSLIM is more like a stock market growth strategy.

The CANSLIM Method of Investing

C – Current Earnings

Has the company made a strong recent earnings announcement, which is considerably more than the earnings one year previously?

From his research, O’Neill discovered that most companies that experienced strong stock price growth had quarterly earnings growth above 70% before the price growth started.

However, that might be true for a small handful of hugely successful companies. Still, to build a portfolio of stocks, or at least have a choice of more companies, he recommends a most recent quarterly (MRQ) earnings per share (EPS) increase of at least 18-20%. He also suggests an accompanying sales growth of at least 25%.

The sales growth check is important because, without consistent sales growth, it is impossible to maintain earnings growth.

Has the company made a strong recent earnings announcement, considerably more than the earnings one year previously?

A – Annual Earnings.

Has the company shown good earnings growth in previous years? O’Neill suggests an annual earnings growth rate of at least 25%. He also suggests checking for a return on equity (ROE) of over 17%, as it implies the company is investing its capital efficiently.

Most stock screeners allow you to filter on 1-, 3-, and 5-year annual earnings growth rates. Select a 5-year annual earnings growth rate. This will help you filter out companies experiencing short-term growth or manipulate accounts to show higher earnings for a particular quarter. You can play with the timescale you use, but this seems like a reasonable criterion.

N – New Products, Management, or Price Highs.

Has the company innovated its product base or injected new management to seek higher performance? Here, we essentially move to a business question.

If a company has a history of innovation or developing products superior to the competition in price, quality, or both, this is an excellent signal for future stock price growth.

According to O’Neill, management or board changes were also a positive indicator. Injecting new blood into an organization’s leadership structure drives growth; New People = New Ideas.

I tend to disagree here; continually injecting or hiring externally to find that magic growth formula rarely works out positively.

Look at the history of Hewlett Packard (Ticker: HPQ); since the founders left, the company has constantly been injecting new management, merging, and spinning off, to the dismay of its shareholders and employees.

Finally, the suggestion is that new stock price highs might encourage further demand for the stock and push prices even higher.

– Supply and Demand.

Does the stock have an increasing demand in the marketplace? Is trading volume increasing with the price?

Here, we get to a core principle: it is the only reason stock prices go up or down. Stock prices decrease if the sellers (supply) outnumber the buyers (demand). If demand outstrips supply, prices go up.

A stock price may go up or down daily, which is largely irrelevant. However, if you see volume growth and stock prices rise over weeks and months, you know demand is higher than supply.

O’Neill recommends that the daily trading volume be higher than the average volume for the stock in the previous three months.

– Leaders

Is the company a leader in its marketplace? This is another key business question about competitive advantage.

A company that is a leader in its industry must have some key competitive advantages, either in the product, service quality, or pricing. However, finding these companies by sifting through every firm’s product listing and doing a competitive market analysis is difficult. So, O’Neill kindly suggests looking for companies with stock price strength higher than their competitors, even above 80% of the stock market.

Essentially, any company near, at, or breaking through its stock price 52-week high is a candidate. Add to this any company outperforming the major market indices regarding price growth. So, to beat the market, you need to select companies that are already beating the market. Does that seem reasonable?

I – Institutional Ownership.

Does the stock have a solid level of institutional ownership? More than 70% of all stocks are owned by institutions, mostly on behalf of their investors. If you have a pension or own ETFs, you will not own the stocks; you own part of the company that holds those stocks for you.

The point here is that you would want to see at least 30% institutional ownership to know that the company is at least on the radar of institutional buyers.

As investment companies have the most buying power, they can make the biggest impact on stock prices; if the company is not interesting to the investment firms, the chances of the stock price moving significantly higher or negligible.

Finally, if institutional ownership is over 90%, how much room is there for the stock price to increase? Not much.

M – Market Direction.

Understanding the overall market direction is important to time your stock purchase effectively.

The market moves in three directions: uptrend, downtrend, or consolidation (sideways). If you buy stocks during a multi-year bear market, then the chances of you making any money are small. During periods of market fear, most company stock prices drop.

According to O’Neill, 3 out of 4 stocks move in the same direction as the market.

The reality is that it takes 3 out of 4 stocks to move upwards to move the market upwards, as the market only reflects all the stock prices. The key takeaway here is that if you buy stocks in a Bull market, you have a much greater chance of making a profit, and that is a fact.

CANSLIM Strategy Explained

The CANSLIM strategy is a flexible investing style that relies on the positive stock price momentum generated by fast-growing, profitable companies with solid quarterly and annual earnings growth. The companies must also have innovative leading products and services in a growing bull market.

Now, let’s step back to understand the overall CANSLIM strategy.

Flexibility: With CANSLIM, a stock has no defined holding period. You may hold the stock for two days or two years. It could be seen as a swing trading strategy or a medium-term buy-and-hold strategy. One thing it is not is a value investing strategy.

The entry point into stock is suggested when the stock price breaks into a new 52-week high. The strategy also suggests cutting your losses and selling if the stock falls 7 to 8. For any given stock, this could happen within a week or over years; therefore, a flexible timeframe.

Momentum: CANSLIM is a momentum strategy. The rules are to buy when the stock is at a new 52-week high, experiencing increased trading volume, and when the overall market is in an uptrend. This is the definition of momentum trading and market timing.

Profitable Growth: The CANSLIM strategy also requires a company to grow earnings strongly. Current quarterly and annual earnings must increase aggressively, along with sales. So, you are looking for profitable, fast-growing companies.

Great Products: Of course, the L in CANSLIM refers to companies leading their industry in product and services, innovation, or stock price growth. This makes sense. Would you want to buy shares in a company falling behind its competitors?

Growing Markets: Finally, the M in CANSLIM refers to growing markets. The market that the company operates in needs to be growing, for example:

  • The widespread rapid adoption of the internet fueled Google’s explosive growth.
  • Over the last eight years, Nvidia’s growth has partly been fueled by the Cryptocurrency craze; their graphics card chips are used in Crypto mining operations.

The CANSLIM strategy is to:

Buy stocks in profitable companies, with great products, in growing markets at the right time.

CANSLIM Stock Screener

A CAN SLIM stock screener must scan for Current and Annual Earnings with a 5-year history. Next, the screener must filter on 52-week stock price highs, the Number of Shares Available, and the share price Relative Strength vs. Competitors. The Institutional Ownership criteria are also critical.

To implement a CANSLIM strategy, you must use a stock screener to automatically scan the entire stock market to find stocks that meet the right criteria.

5. Select Your CANSLIM Stocks

The scan produces a list of 32 stocks from the entire stock exchange listing of over 12,000 companies. Even though this list is small, 32 may still be too many to hold at any one time. So, you must carefully select the right companies to invest in.

I suggest you combine the CANSLIM strategy with Warren Buffett’s margin of safety concept in value investing. The margin of safety measures how undervalued a stock is compared to its intrinsic value. The more undervalued a stock is, the safer the investment.

So, you could narrow down your stock selection using, for example, the top 10 stocks with the highest margin of safety. See the image below.

CANSLIM Stock Trading System

The CANSLIM stock trading strategy entails deciding how often you will rebalance and rotate the stocks within your CANSLIM portfolio and how much cash you will allocate to each stock.

CANSLIM Portfolio Rebalancing

One example of how you could do it comes from the backtested CANSLIM results in the previously mentioned OPBMII paper. This paper suggests rebalancing the portfolio weekly:

Rebalancing – It should be noted that the system rebalances (re-runs the screen and possibly select new holdings) every week.

Of course, a weekly portfolio rebalance may be time-consuming, so you might want to lengthen it to bi-monthly or monthly. However, the rebalance does not need to be expensive, as now there are brokerage accounts like our partner Firstrade that offer $0 commissions. This means a regular rebalance will not cost you anything.

CANSLIM Portfolio Cash Allocation

The CANSLIM backtesting research paper used cash allocation, holding a maximum of 10 stocks, each worth 10% of the invested portfolio capital.

Weighting Ideally, the system will select 10% weighting to each position with a maximum of 10 positions.

This sounds reasonable to me if you are investing at least $10,000, which would be $1,000 per stock.

Exiting & Selling the Stocks

Academic research suggests buying stocks when they meet the CANSLIM criteria and selling stocks if they lose 7%.

Exits/Closing Positions if a stock drops 7% after purchase, it will be removed but considered at the rebalance the next week (if it still passes criteria).

  1. Thank you for the helpful article.

    Regarding the note under Exiting & Selling the Stocks “The tests also sold stocks if they lost 7%, O’Neill suggested 20%, but I find 20% too much to risk on any one trade.”

    O’Neill’s does not suggest waiting until you lose 20% to sell. His rule matches the test which is to sell if you lose 7% to 8%. This may be a mix-up with his suggestion to sell once you have gained 20% unless you gain 20% quickly which may signal more gains to come.

  2. Great analysis and explanation. I tried LSTB method starting last October and I am happy with it. I am going to try this strategy with 10% of my account with all of it divided equally among 10 stocks.

  3. Doesn’t the CANSLIM strategy utilize a relative strength rank (vs competitors)? It appears that the screener shown is using the Relative strength index > 69 (oversold vs overbought). Wouldn’t a RSI >70 indicate the stock is being overbought and due for a declining adjustment?
