Perseus Proteomics (TSE:4882) Sloan Ratio % Explanation
A former University of Michigan researcher, Richard Sloan's 1996 paper found that shares of companies with small or negative accruals vastly outperform (+10%) those of companies with large ones. In fact, for the 40-year period between 1962 and 2001, buying the lowest accrual companies and shorting the highest accrual companies resulted in an average annual compounded return of 18%, more than double the S&P 500's 7.4% annual return over the same period.
If the Sloan Ratio is between -10% and 10%, the company is in the safe zone and there is no funny business with accruals.
If the Sloan Ratio is less than between -25% and -10% on the negative side, and between 10% and 25% on the positive side, this is a warning stage of accrual build up.
If the Sloan Ratio is less than -25% or greater than 25%, and this ratio is consistent over several quarters or even years, be careful. Earnings are highly likely to be made up of accruals.
As of Mar. 2026, Perseus Proteomics has a Sloan Ratio of -3.37%, indicating the company is in the safe zone and there is no funny business with accruals.
