Jim Slater invented the price-earnings to earnings-growth ratio (PEG)


Jim Slater explained his investment strategy in his weekly column.

He tended to like small growth companies, particularly the ones he believed were undervalued by the market.

The investment matrix Slater would use to seek out these stocks would be the PEG ratio, which combines growth and value investing by comparing a company’s price-earnings ratio against its expected earnings per share growth rate.

So long as a stock had a high earnings growth a stock’s P/E ratio the stock was not too expensive and represented value.

The term “Asset stripping” was also popularized by Jim Slater, which referred to the acquisition and subsequent disposal of company assets, a practice that many viewed as unnecessarily or overly harsh in terms of costs to company employees.

Most leading brokers cannot spare the time and money to research smaller stocks. You are therefore more likely to find a bargain in this relatively under-exploited area of the stock market – Jim Slater
