What is CAN SLIM?

The CAN SLIM Investing System has its roots in a landmark study William J. O'Neil launched as a young stockbroker in the late 1950s. He wanted to know what characteristics separate the best performing stocks from the average stocks. What signs do they flash in the early stages of their massive price moves? And just as importantly, as they eventually run out of steam, what sell signals do they display that show it's time to lock in your profits?

To find the answers, he began studying the best stocks of all time, analyzing every available performance metric. That research continues to this day, and now covers every market cycle and top-performing stock since 1880.

O'Neil found that year after year, decade after decade, the best stocks display seven common traits just before they make their biggest gains. Each letter in the CAN SLIM Investing System stands for one of those seven traits, and they form the basis of the buy rules you'll find in How to Buy Stocks.

Whether it's Texas Instruments in the 1950s, Microsoft in the 1980s or, more recently, Apple, Google and Tesla, the best stocks tend to share these same seven characteristics at the start of their huge price moves.

O'Neil also studied what happens to leading stocks after they've had a big run. Just as they share certain traits before they jump higher, they also exhibit similar warning signs as they peak and begin to decline. Those signals form the basis of the sell rules you'll find in How to Sell Stocks.

With stock market history on his side, O'Neil used the CAN SLIM Investing System to achieve remarkable investing success and become the youngest person at the time to buy a seat on the New York Stock Exchange. And in the decades since, countless other investors — from all walks of life — have also used the CAN SLIM approach to achieve lifelong money-making skills and financial security.
