What is the Sloan Accrual Anomaly?
The empirical pattern, documented by Richard Sloan in 1996, that firms with high accruals (earnings far above cash flow) systematically underperform firms with low accruals over the following 12 months. One of the most robust quality signals in equity markets.
Accruals are the gap between reported earnings and operating cash flow. Sloan (1996) showed that firms with high accruals (earnings significantly above OCF) underperformed firms with low accruals by approximately 10 percentage points over the following year, holding size and value factors constant. The pattern persists because high accruals signal lower earnings quality - earnings driven by accounting estimates rather than cash.
The mechanism
Reported earnings can rise without operating cash flow rising. The gap, called accruals, captures everything from inventory build-ups to receivables to revenue recognised before cash arrives. Sloan's observation was that high accruals systematically mean-revert: the earnings flatter the picture today but tend to disappoint in the next 12 months. Low-accrual firms, where earnings are backed by cash, tend to surprise positively.
How invest-like applies it
The accrual ratio appears inside the Buffett-Fit financial-health pillar and the Smith framework cash- conversion test. A high accrual ratio is treated as a deal-breaker hint: cash conversion below 70% pulls the financial-health pillar score down meaningfully. The /benchmarks/ page cites Sloan's 1962-1991 sample as an academic baseline for the invest-like consensus alpha.
Frequently asked questions
What is the Sloan Accrual Anomaly?
The pattern that firms with high accruals (earnings above cash flow) underperform firms with low accruals. Sloan (1996) measured a roughly 10 percentage point spread over the following year.
Why does the anomaly persist?
Because most investors don't decompose earnings into cash vs accrual components. The gap is publicly available in the cash-flow statement but rarely surfaced in headline earnings coverage, so the signal persists despite being well-documented academically.
How does invest-like use this?
The accrual ratio drives the Buffett-Fit financial-health pillar and the Smith framework cash-conversion test. High accruals function as a deal-breaker hint that pulls the relevant pillar score down.
