William J. O'Neil

Investment Style
O'Neil blends a mixture of quantitative and qualitative strategies in his performance-oriented investing approach. In brief, his investment style is to seek out only those growth stocks that have the greatest potential for swift price rises from the moment they are purchased.

Essentially, Bill O'Neil's motto is "buy the strong, sell the weak." His criteria for identifying a stock that's about to head for the stratosphere are summarized in his well-known acronym CANSLIM:

C – Current quarterly earnings per share have increased sharply from the same quarters' earnings reported in the prior year (at least 25%).

A – Annual earnings increases at a compound rate of no less than 25% (P/E is unimportant – probably in the range of 20 to 45 with these stocks) annually over the last five years.

N – New products, new management, and new highs. Stocks with a good "story."

S – Supply and demand. The less stock available, the more buying will drive up the price. Look for stocks with 10 to 12 million shares outstanding.

L – Leaders and laggards. Stick with those stocks that outperform and shed those that underperform.

I – Institutional ownership. Favor companies that are "underowned" by the top professional investors. (For related reading, see Institutional Investors And Fundamentals: What's The Link?)

M – Market direction. Buy stocks on major downturns, but avoid purchases after a decline of 10% or more gets underway.
