What is Quantitative Finance?
Definition
Quantitative finance uses sophisticated mathematical models for:

Finance (Solid but Secondary)
Must-Knows:
- Derivatives (options, futures, swaps).
- Market Microstructure.
- Regulations (Basel III, MiFID II).
- Fixed Income and Bond Pricing.
Reality Check: Math/Code > Pure Finance. You will learn the finance specifics on the job.
📊 Complement your skills: Excel remains useful even for quants for rapid prototyping and rough analysis.
