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.

Although not strictly a technical analysis tool, the
CANSLIM approach combines worthy 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 Earnings
Earnings 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 Growth
Earnings 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 Highs
A 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 Outstanding
More 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).
Leader
Although 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 Sponsorship
The 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 Direction
This is the most important element in the formula.
Even the best stocks can lose money if the general market goes into a
slump. Approximately 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."
