Quant Thinking

Build the mental models that separate top quants from everyone else.

About this pathway

Quant Thinking is not about memorizing formulas — it's about learning to reason probabilistically. This pathway develops the intuition for expected value, Bayesian reasoning, risk/reward tradeoffs, and the mental frameworks used by traders and researchers at top firms.

Who it's for

Anyone entering quant trading, research, or systematic investing. Essential for all roles at trading firms regardless of technical background.

Skills covered

Expected value & probability distributions
Bayesian updating & conditional reasoning
Risk/reward thinking & Kelly criterion
Fermi estimation & order-of-magnitude thinking
Game theory fundamentals
Decision frameworks under uncertainty

Example problems

A taste of what you'll work through.

1

You flip a fair coin repeatedly. What is the expected number of flips needed to see HH?

2

A trader offers you a game: roll two dice, win the product of the values, but pay $20 to play. What is the EV?

3

Given a biased coin with unknown P(H), you observe 7 heads in 10 flips. Update your estimate using Bayes.

Expected outcome

After completing this pathway, you will naturally think in terms of probabilities, reason clearly under uncertainty, and approach any quant interview question with structured, probabilistic thinking.
