Adtran Networks SE  (OTCPK:ADVOF) 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.

According to How to Beat the Market with the Sloan Ratio:

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 Dec. 2025, Adtran Networks SE has a Sloan Ratio of -6.68%, indicating the company is in the safe zone and there is no funny business with accruals.
