In the world of financial markets, information is power. Those who have access to superior information have a significant advantage over those who do not. This is the fundamental problem of information asymmetry, and it is at the heart of many market anomalies, including the accrual anomaly.

This distinction lies at the heart of one of the most persistent and widely studied market anomalies: the accrual anomaly. The seminal 1996 paper by

For investors and traders, the ability to identify the early warning signs of financial distress is a important skill. A company that is on the road to ruin can be a catastrophic investment for a long-only investor and a lucrative opportunity for a short-seller. One of the most effective and reliable indicators of impending financial dist

A quantitative guide to building and backtesting a trading strategy based on the net stock issuance anomaly. We cover portfolio construction, risk management, and performance analysis.

Previous articles have established the accrual anomaly as a robust and persistent feature of financial markets, driven by the differential persistence of cash flows and accruals. However, treating accruals as a single, monolithic number can obscure important details.

By decomposing total accruals into their constituent parts, we can g
