### Here is the abstract from the research paper

We propose a conservative investment formula which selects 100 stocks based on three criteria:

Low return volatility,

High net payout yield, and

Strong price momentum.

We show that this simple formula gives investors full and efficient exposure to the most important factor premiums, and thus effectively summarizes half a century of empirical asset pricing research into one easy to implement investment strategy.

With a compounded annual return of 15.1 percent since 1929, the conservative formula outperforms the market by a wide margin. It reduces downside risk and shows a positive return over every decade.

The formula is also strong in European, Japanese and Emerging stock markets, and beats a wide range of other strategies based on size, value, quality, and momentum combinations.

The formula is designed to be a practically useful tool for a broad range of investors and addresses academic concerns about ‘p-hacking’ by using three simple criteria, which do not even require accounting data.
