As an investor, you might be well aware of what a daunting task it is to invest in the stock market. Similarly, both field experts and amateurs are also in pursuit of solid strategies. Not to mention since there are tonnes of strategies available, so it is now more important to choose the right approach. As an investor or a trader, you may have a specific financial goal, risk tolerance, and investment style. This makes it crucial that whichever strategy you choose adheres to these factors.

CANSLIM is one such widely popular strategy first developed in 1950 by the founder of Investor’s Business Daily, William J. O’Neil. In this blog, we will understand how even decades later, the strategy is still used in today’s very dynamic stock environment. If you are hoping to harness CANSLIM, this blog can be your ultimate guide.

Breaking down CANSLIM

In 1950, William J. O’Neil identified seven of the most critical factors that can help you select winning stocks. CANSLIM is the acronym for all these factors, with each letter representing a specific criterion that an investor must consider when evaluating a stock. Let’s focus on each factor individually:

C – Current earningsThe first step is to look at a company’s current earnings per share (EPS). It helps investors in identifying entities with stronger profits.
A – Annual earningsConsistent annual earnings growth is an important factor to account for. Consider a company’s annual earnings over at least past five years. It will serve as a reflection of their ability to generate long-term profits.
N – New products/servicesThe strategy emphasizes companies that proactively launches innovative products. Investing in these industry leaders is preferable over laggards as they have a distinct competitive edge from innovation.
S – Supply and demandIt is vital to understand the supply and demand dynamics of stocks for better price appreciation. While the stocks with low supply and high demand offer significant price appreciation, the reverse of it is also true.
L – Leader or laggardSimilar to the N-concept, as an investor, you must always choose leaders over laggards as they have stronger growth potential.
I – Institutional sponsorshipLook out for stocks with greater institutional ownership. Institutional investors like mutual funds and pension funds have a major impact on stock prices.
M – Market directionLast, but not least, look at the direction the overall market is heading. By investing in stocks during an upward trend in the market, you may have a higher chance of success.

CANSLIM in action

Now that we have more clarity on the different components of CANSLIM, let’s take a stepwise look into how this strategy works in practice:

  1. Screening stocks – Start by screening stocks. Identify the companies that tick the different criteria set by CANSLIM including EPS, annual earnings growth, market leadership, institutional sponsorship, and innovation.
  2. Technical analysis – Conduct a technical analysis which will involve the assessment of a stock’s price and volume patterns on charts. There is a proprietary chart called the “cup and handle” that can pinpoint potential buying opportunities.
  3. Risk management – Setting stop-loss orders can help limit potential losses. Avoid stocks that have already seen price surges and mitigate risks.
  4. Continuous monitoring – It is very important to always keep a close eye on your investments and the overall market directions. If at any point the investment/market fails to meet the CANSLIM criteria, it is ideal to dump it.
  5. Portfolio diversification – As important as it is to identify the most suitable stocks, it is equally necessary to diversify your portfolio. This will help spread risk.

As with any other strategy, CANSLIM offers a bouquet of a myriad of benefits as well as several inherent risks. It is important to be aware of both.
