Moontower Quant Codex – Great place to read and learn options.

Party at the Moontower – Created by the author of Moontower Quant Codex, where he writes about a wider range of topics, not just limited to options. Frankly speaking, this website inspired me to create Vol Percolation.

The Convexity Maven – Harley S. Bassman, the creator of the website, describes the goals behind the Convexity Maven as follows: “My goal is to synthesize large ideas into reasonable investment themes by taking a dispassionate view of the entire landscape and to avoid being distracted by short-term noise (local volatility). Most importantly, to use Common Sense, a skill that is not of great value during formal schooling, but is the fulcrum of real life.”

The Daily Dirtnap (NOT FREE) – The daily dirtnap is a market newsletter for professional investors edited by Jared Dillan. It covers a wide range of topics, including market trends, trade ideas, and notably, cats (yes, feline friends). From my perspective, the most remarkable aspect of the daily dirtnap is its ability to call out market sentiment peaks and troughs. “Be fearful when others are greedy. Be greedy when others are fearful.” – Warren Buffett
