Abstract

The invention is in the field of using a computer to select corporate stocks for investment. Fifty stocks are selected from a database on the basis of certain criteria. The stocks are acquired in equal proportions, and the portfolio is rebalanced at the end of an annual term. A method of the present invention uses either a growth strategy, a value strategy, or both strategies. Growth Model 3 strategy selects the stocks with the best 1-year price performance from All Stocks (stocks with market capitalization more than $150 million) with earnings gains for five consecutive years that also have price-to-sales ratios below 1.5. Value Model 3 strategy selects market leading stocks with the highest dividend yields (excluding utilities so they do not dominate the list). Market leading stocks come from the Large Stocks Universe and have: more common shares outstanding than the average stock in the database, cashflows per share exceeding the database mean, and corporate sales that are 1.5 times the database mean. A stock portfolio may be constructed which uses both Growth Model 3 and Value Model 3 in chosen proportion to one another. At the end of an annual term, the amount of money generated by the two strategies is pooled and then re-invested in accordance with the chosen proportion (which may change over time).
