Hey guys! I’ve just released a refined, compact edition of one of my newsletter series on the foundations of quantitative trading. It is a theoretical introduction designed for aspiring quants who are beginning to explore the field. The focus is on first principles, method, and the conceptual framework behind quantitative trading. Link in the comments. I hope you enjoy it.

One thing is a portfolio that performed well historically and another to demonstrate that the portfolio-selection process will work out of sample.

The authors acknowledge in Section 3.1 that the dynamic program uses the entire realized order-flow path of the evaluation day, including information that becomes available after each trading decision 😬 in other words, look-ahead bias

There’s only one reason I haven’t told X to fuck off. 🤣
Auditor resignations are another data source because it can reflect governance and risks. Indeed, his job can be assessed as any other event. Here, the bearish setup carries high conviction when a resignation intersects with deteriorating liquidity.

Resolved filing delays create opportunities when the 10-Q or 10-K report numbers that match expectations. The long thesis strengthens once accounting issues are clear, and the stock begins recovering the NT drop. Here the entry triggers after the filing posts.

Interesting interpretation for the Sunday morning. I only have to say that learning a representation of market microstructure is not equivalent to learning a predictive, economically useful, or causally accurate model of financial markets.

NT 10-K is like a disclosure-risk event. With it you can score the stated reason for delay (may accounting, expected resolution time, or management). Use it as a long-avoidance filter first, then short only when price and liquidity confirm deterioration.
