5 How to Develop an Alpha. I: Logic with an Example
Step 1 → Collect Information
Step 2 → Come Up with an Idea
Step 3 → Translate into a Mathematical Expression
Step 4 → Transform the Raw Expression by Applying Operations
Step 5 → Final Robust Alpha
Step 6 → Translate into Positions in a Financial Instrument
Step 7 → Check for Robustness
6 How to Develop an Alpha. II: A Case Study
