The son of Philip Fisher, who is considered the "Father of Growth Investing", Kenneth Fisher is a money manager, bestselling author, and longtime Forbes columnist. The younger Fisher wowed Wall Street in the mid-1980s when his book Super Stocks first popularized the idea of using the price/sales ratio (PSR) as a means of identifying attractive stocks. According to his alma mater, Humboldt State University, Fisher is also one of the world's foremost experts on 19th century logging. Appropriately, Fisher's firm, Fisher Investments, is located in a lush forest preserve in Woodside, California, where the contrarian-minded Fisher says he and his employees can get away from Wall Street groupthink.

Validea used the investment strategy outlined in the book Super Stocks written by Kenneth Fisher to create our Price/Sales Investor portfolio.
Fisher found that earnings -- even the earnings of good firms -- could vary from year to year based on things (accounting changes, decisions to upgrade facilities, increased research costs that will lead to bigger profits down the line) that had little to do with the prospects of the company's underlying business. Sales, however, were far more stable and thus a better indicator of the strength of a company's business, making the PSR a very useful tool. Fisher wanted stocks with low PSRs, and he used different standards for different types of companies. He also wanted to see strong earnings growth, high profit margins, and low debt. In addition, for technology and medical companies, Fisher viewed research as a commodity. When analyzing these firms, he used the "price/research" ratio (PRR), which divides a firm's market cap by the amount it is spending on research. Fisher has changed his strategy today, but his PSR-focused approach has continued to produce strong results for us.
Performance Disclaimer: Returns presented on Validea.com are model returns and do not represent actual trading. As a result, they do not incorporate any commissions or other trading costs or fees. Model portfolios with inception dates on or after 12/30/2005 include a combination of back tested and live model returns. The back-tested performance results shown are hypothetical and are not the result of real-time management of actual accounts. The back-testing of performance differs from actual account performance because the investment strategy may be adjusted at any time, for any reason and can continue to be changed until desired or better performance results are achieved. Back-tested returns are presented to provide general information regarding how the underlying strategy behind the portfolio performed in our historical testing. A back-tested strategy has the benefit of hindsight and the results do not reflect the impact that material economic or market factors may have had on advisor's decision-making if actual client assets were being managed using this approach.
Optimal portfolios presented on Validea.com represent the rebalancing period that has led to the best historical performance for each of our equity models. Each optimal portfolio was determined after the fact with performance information that was not available at portfolio inception. As a result, an investor could not have invested in the
optimal portfolio since its inception. Optimal portfolios are presented to allow investors to quickly determine the portfolio size and rebalancing period that has performed best for each of our models in our historical testing.
Both the model portfolio and benchmark returns presented for all equity portfolios on Validea.com are not inclusive of dividends. Returns for our ETF portfolios and trend following system, and the benchmarks they are compared to, are inclusive of dividends. The S&P 500 is presented as a benchmark because it is the most widely followed benchmark of the overall US market and is most often used by investors for return comparison purposes. As with any investment strategy, there is potential for profit as well as the possibility of loss and investors may incur a loss despite a past history of gains. Past performance does not guarantee future results. Results will vary with economic and market conditions.
