I wrote a post trying to summarize 12 market inefficiencies/factors that can improve an investment process: value, momentum, profitability, accruals, shareholder yield, illiquidity, low beta, small caps, etc.
For each advantage:
- Plain-English explanation
- Pros and cons
- Why it exists and how it shows up in real businesses
- Signals that suggest durability vs. decay
- Common patterns and notes from real companies
Built mainly as a thinking framework for investors, not a stock-picking list.
