CAN SLIM refers to the seven-pronged mnemonic publicized by the American newspaper Investor's Business Daily, which claims to be a checklist of the characteristics performing stocks tend to share before their biggest gains. It was developed by Investor's Business Daily editor William O'Neil who has reportedly made several hundreds of millions of dollars by consistently using its approach.[1]

The investing mechanism and process[edit]

CAN SLIM is a growth stock investment strategy formulated from the study of the 500 best performing stock market winners dating back to 1953 in the book How to Make Money in Stocks: A Winning System In Good Times or Bad, 3rd Edition (May 23, 2002) ISBN 0-07-137361-6. by William J. O'Neil. This strategy involves implementation of both technical analysis and fundamental analysis.

The goal of the strategy is to discover leading stocks before they make major price advances. These pre-advance periods are "buy points" that are emerging from price consolidation areas (or "bases"), typically in the form of a "cup & handle" price pattern, of at least 7 weeks on weekly price charts.

The strategy is one that strongly encourages cutting all losses at no more than 7% or 8% below the buy point, with no exceptions, to minimize losses and to preserve gains. It is stated in the book, that buying stocks from solid companies should generally lessen chances of having to cut losses, since a strong company (good current quarterly earnings-per-share, annual growth rate, and other strong fundamentals) will usually shoot up—in bull markets—rather than descend.

Some investors have criticized the strategy when they didn't use the stop-loss criterion; O'Neil has replied that you have to use the whole strategy and not just the parts you like.

O'Neil has stated that the CANSLIM strategy is not momentum investing, but that the system identifies companies with strong fundamentals—big sales and earnings increases which is a result of unique new products or services—and encourages buying their stock when they emerge from price consolidation periods (or "bases") and before they advance dramatically in price.

Mnemonic[edit]

The seven parts of the mnemonic are as follows:[1]

  • C stands for Current earnings. Per share, current earnings should be up to 25%. Additionally, if earnings are accelerating in recent quarters, this is a positive prognostic sign.
  • A stands for Annual earnings, which should be up 25% or more in each of the last three years. Annual returns on equity should be 17% or more
  • N stands for New product or service, which refers to the idea that a company should have a new basic idea that fuels the earnings growth seen in the first two parts of the mnemonic. This product is what allows the stock to emerge from a proper chart pattern of its past earnings to allow it to continue to grow and achieve a new high for pricing. A notable example of this is Apple Computer's iPod.
  • S stands for Supply and demand. An index of a stock's demand can be seen by the trading volume of the stock, particularly during price increases.
  • L stands for Leader or laggard? O'Neil suggests buying "the leading stock in a leading industry". This somewhat qualitative measurement can be more objectively measured by the Relative Price Strength Rating (RPSR) of the stock, an index designed to measure the price of stock over the past 12 months in comparison to the rest of the market based on the S&P 500 or the TSE 300 over a set period of time.
  • I stands for Institutional sponsorship, which refers to the ownership of the stock by mutual funds, particularly in recent quarters. A quantitative measure here is the Accumulation/Distribution Rating, which is a gauge of mutual fund activity in a particular stock.
  • M stands for Market indexes, particularly the Dow Jones, S&P 500, and NASDAQ. During the time of investment, O'Neil prefers investing during times of definite uptrends of these three indices, as three out of four stocks tend to follow the general market pattern.
