What is
CAN SLIM®?
CAN SLIM®
is a formula created by William J. O'Neil, who is the founder of the Investor's
Business Daily and author of the book
How to Make Money in Stocks - A Winning
System in Good Times or Bad.
Each letter in the word CANSLIM stands for one of
the seven chief characteristics that are commonly found in the greatest
winning stocks. In his book, he cites many examples including:
- Texas Instruments, whose price
rose from $25 to $250 from January 1958 to May 1960
- Xerox, which went from $160 to
the equivalent of $1340 from March 1963 to June 1966
- Syntex, which leaped from $100
to $570 in the last six months of 1963
- Dome Petroleum advanced 1000%
in the 1978-1980 market
- Prime Computer rose 1595% in the
1978-1980 market
- Limited Stores' 3500% increase
from 1982 to 1987.
The C-A-N-S-L-I-M characteristics are often
present prior to a stock making a significant rise in price, and making
huge profits for the shareholders!
O'Neil explains how he conducted an intensive
study of 500 of the biggest winners in the stock market from 1953 to 1990.
A model of each of these companies was built and studied. Again and again,
it was noticed that almost all of the biggest stock market winners had very
similar characteristics just before they began their big moves.

C = Current
quarterly earnings per share.
They should be up a minimum of 25% - 50%
over the year earlier. In fact, of the 500 best performing stocks O'Neil
studied in the 38 years from 1953 to 1990, three out of four had earnings
increases averaging more than 70% in the latest publicly reported quarter
before the stocks began their major price advance. The one out of four that
didn't show solid quarterly increases did so in the very next quarter, and
those increases averaged 90%!

A = Annual
earnings per share.
There should be meaningful growth over the
last five years. The annual compounded growth rate of earnings in the superior
firms should be from 25% to 50%, or even more, per year. With all of this
emphasis on earnings, it is important to understand something about Price-Earnings
Ratios (P/E). Factual analysis of the greatest winning stocks shows that
P/E ratios have very little to do with whether a stock should be bought
or not! In fact, you will automatically eliminate most of the best investments
available if you're not willing to by a stock that trades with a high P/E.
Remember earlier when I mentioned Xerox? In 1960 it traded at a 100 P/E
- before it went up 3300% from $5 to $170 (adjusting for the stock splits).
Genentech was priced at 200 times earnings in November 1985, and it bolted
300% in the next 5 months. Syntex sold for 45 times earnings in 1963, before
it advanced 400%. For years analysts have misused P/E ratios, and it's amazing
to me how so many people will still ask about a company's P/E before they
ask about a company's earnings growth.

= New product/management/price high.
Usually it is a new product or service that
causes the big earnings acceleration we're looking for. Consider these examples:
- Rexall's new Tupperware division,
in 1958, helped the stock go from $16 to $50.
- Thiokol came out with new rocket
fuels for missiles back in 1957-1959. The stock blasted from $48 to
the equiuvalent of $355.
- In 1957-1960, Polaroid came out
with the "picture in a minute" self-developing camera, the stock went
from $65 to $260. Then in 1965-1967 they came out with a color-film
version. The stock repeated with an amazing, split adjusted, rise from
$23 to $133.
- Syntex, in 1963, began marketing
the oral contraceptive pill. In six months the stock soared from $100
to $550.
- Computervision stock advanced
1235% in 1978-1980, with the introduction of Cad-Cam factory automation
equipment.
- Price Company went up 15 fold
in 1982-1986 while opening their chain of wholesale warehouse membership
stores.
Get the point? 95% of the greatest winners
in the 38 year study O'Neil conducted were companies that had a major new
product or service.
The other important thing to consider is
the price of the stock. Most people miss the biggest winners in the market
because of what O'Neil refers to as "the great paradox" of the stock market.
It is hard to accept, but the stocks that seem too high and risky to the
majority usually go higher and what seems low and cheap usually goes lower.
If you don't think this is true, I challenge you to look in an old newspaper
from a few months ago and observe a good number of stocks highlighted because
they hit new highs and new lows. Then see where they are today. Most of
the highs will be higher, and the lows will be even lower.

S = Supply/Demand:
Small Cap + Volume
Supply and demand dictates the price of almost
everything in your life. The law of supply and demand is more important
than all the analyst opinions on Wall Street. The price of a stock with
400 million shares is hard to budge up because of the large supply of stock
available. Yet, if a company has only 2 or 3 million shares outstanding,
a reasonable amount of buying can push the price up rapidly because of the
small available supply. If you are choosing between two stocks to buy, one
with 60 million shares outstanding and one with 10 million shares, with
all other factors equal, the smaller one will usually be the bigger mover.
Stocks that have a large percentage owned by top management are generally
better prospects. Again referencing O'Neil's 38 year study, more than 95%
of the companies had less than 25 million shares outstanding when they had
their greatest period of earnings improvement and stock price performance.
Foolish stock splits can hurt a stock's performance.
Watch out for companies that split their stock 2 or 3 times in just a year
or two. The splitting creates a larger supply and may make a company's stock
performance more lethargic, like many "big cap" companies. Large holders
who thinking of selling are often inclined to sell their 100,000 share positions
before a 3-for-1 split would have them looking to sell 300,000. Smart short
sellers (an infinitesimal group) pick on stocks beginning to falter after
enormous price runups and splits, realizing that the potential number of
shares for sale (particularly by funds) has dramatically been increased.

L = Leader
People often buy stocks they're comfortable
and familiar with, like an old pair of shoes. Usually these are draggy slow-pokes
rather than leaping leaders. It is really important to look at how your
stock is performing in relation to the overall market. The 500 best performing
stocks from 1953 to 1990 averaged a relative price strength of 87 (scale
of 1-99) just before they began their major advances in price. Avoid laggard
stocks and look for genuine leaders.

= Institutional Sponsorship
It takes big demand to move a stock significantly
higher in price. Institutional buyers are the most powerful source. You
don't need a large number of institutional owners, but should have at least
a few. No institutional sponsorship in a stock is a bad sign because odds
are that many institutional investors looked at the stock and passed it
over. The things we are looking for with C-A-N-S-L-I-M are really signs
that the bigger money (mutual funds, banks, insurance companies, pension
funds, etc.) is coming into the stock. See that there is a better-than-average
performance record by at least a few of the institutional owners.
Another good thing about some institutional
sponsorship is that it provides buying support for the stock. Beware of
stocks that become "overowned". By the time performance is so obvious that
almost all institutions own it, it is probably too late. Pay attention to
whether the number of institutional owners is increasing or decreasing.

= Market Direction
You can be right on everything else, but if you are
wrong about the direction of the broad market you are still likely to lose
money. The best way to analyze the overall market is to follow and understand
every day what the general averages are doing. The difficult to recognize,
but meaningful changes in the behavior of the market averages at important
turning points is the best indicator of the condition of the whole market.
What signs should you look for to detect a market
top? On one of the days in the uptrend, the total volume for the market
will increase over the preceding day's high volume, but the Dow's closing
average will show stalling action, or substantially less upward movement,
than on prior days.
The spread between the daily high and low of the market
index will likely be a bit larger than on the earlier days. Normal market
liquidation near the market peak will only occur on one or two days, which
are part of the uptrend. The market comes under distribution while it is
advancing! This is one of the reasons so few people know how to recognize
distribution (selling).
Immediately following the first selling near the top,
a vacuum exists where volume may subside and the market averages will sell
off for four days or so. The second, and probably the last early chance
to recognize a top reversal is when the market attempts it's first rally,
which it will always do after a number of days down from it's highest point.
If this first attempt to bounce back follows through on the third, fourth,
or fifth rally day either on decreased volume from the day before, or if
the market average recovers less than half of the initial drop from it's
former peak to the low, the comeback is feeble and sputtering when it should
be getting strong. Frequently the first attempt at a rally during the beginning
of a downtrend will fail abruptly. Possibly after a one day resurgence,
the second day will open up strong, only to sell off toward the end of the
day and suddenly close down.
After an advance in stocks for a couple of years,
the majority of the original price leaders will top, and you can be fairly
sure the overall market is going to get into trouble. It is very important
to pay attention to the way the leading stocks are acting.
