| Overview
CANSLIM is an acronym for a stock market investment method developed by William O'Neil.  
O'Neil is the founder and chairman of Investor's Business Daily, a national business 
newspaper.  He also heads an investment research organization, William O'Neil & Company, 
Inc.
 Drawing from his study of the greatest money-making stocks from 1953 to 1985, O'Neil 
developed a set of common characteristics that each of these stocks possessed.  The key 
characteristics to focus on are captured in the acronym CANSLIM.

technical and fundamental concepts.  The CANSLIM approach is covered in detail in O'Neil's 
book, How To Make Money In Stocks. 
 Interpretation
The following text summarizes each of the seven components of the CANSLIM method.
Current Quarterly EarningsEarnings per share ("EPS") for the most recent quarter should be up at least 20% when 
compared to the same quarter for the previous year (e.g., first quarter of 1993 to the 
first quarter of 1994).Annual Earnings GrowthEarnings per share over the last five years should be increasing at the rate of at least 
15% per year.  Preferably, the EPS should increase each year.  However, a single year 
set-back is acceptable if the EPS quickly recovers and moves back into new high 
territory.New Products, New Management, New HighsA dramatic increase in a stock's price typically coincides with something "new."  This 
could be a new product or service, a new CEO, a new technology, or even new high stock 
prices.One of O'Neil's most surprising conclusions from his research is contrary to what many 
investors feel to be prudent.  Instead of adhering to the old stock market maxim, "buy low 
and sell high," O'Neil would say, "buy high and sell higher."  O'Neil's research concluded 
that the ideal time to purchase a stock is when it breaks into new high territory after 
going through a two to 15 month consolidation period.  Some of the most dramatic increases 
follow such a breakout, due possibly to the lack of resistance (i.e., sellers). Shares OutstandingMore than 95% of the stocks in O'Neil's study of the greatest stock market winners had less 
than 25 million shares outstanding.  Using the simple principles of 
supply and demand, restricting the shares 
outstanding forces the supply line to shift upward which results in higher prices.A huge amount of buying (i.e., demand) is required to move a stock with 400 million 
shares outstanding.  However, only a moderate amount of buying is required to propel a 
stock with only four to five million shares outstanding (particularly if a large amount is 
held by corporate insiders). LeaderAlthough there is never a "satisfaction guaranteed" label attached to a stock, O'Neil found 
that you could significantly increase your chances of a profitable investment if you 
purchase a leading stock in a leading industry.He also found that winning stocks are usually outperforming the majority of stocks in 
the overall market as well. Institutional SponsorshipThe biggest source of supply and demand comes from institutional buyers (e.g., mutual 
funds, banks, insurance companies, etc).  A stock does not require a large number of 
institutional sponsors, but institutional sponsors certainly give the stock a vote of 
approval.  As a rule of thumb, O'Neil looks for stocks that have at least 3 to 10 
institutional sponsors with better-than-average performance records.However, too much sponsorship can be harmful.  Once a stock has become 
"institutionalized" it may be too late.  If 70 to 80 percent of a stock's outstanding 
shares are owned by institutions, the well may have run dry. The result of excessive 
institutional ownership can translate into excessive selling if bad news strikes. O'Neil feels the ideal time to purchase a stock is when it has just become discovered by 
several quality institutional sponsors, but before it becomes so popular that it appears on 
every institution's hot list. Market DirectionThis is the most important element in the formula.  Even the best stocks can lose money if 
the general market goes into a slump.  Approxamately seventy-five percent of all stocks 
move with the general market.  This means that you can pick stocks that meet all the other 
criteria perfectly, yet if you fail to determine the direction of the general market, your 
stocks will probably perform poorly.Market indicators are designed to help 
you determine the conditions of the overall market.  O'Neil says, "Learn to interpret a 
daily price and volume chart of the market averages.  If you do, you can't get too far off 
the track.  You really won't need much else unless you want to argue with the trend of the 
market." TOP |
