Hi, I'm
Siddhant Shah
Equity Research Associate at Rosenblatt Securities in New York, supporting FinTech and Digital Assets coverage. I came to markets from mathematics and data, and this is where I write about what I'm building and thinking about.
Who I am
I came to markets from mathematics. Bayesian inference, ensemble methods and a great deal of time with messy data all came from my years in Boston, and they are still the toolkit. For four years I taught maths and physics to olympiad students in India, which did more for how I explain things than anything since.
Equity Research Associate at Rosenblatt Securities, supporting the FinTech and Digital Assets coverage. Before that, part-time quantitative work at Boston University alongside my master's.
MS in Applied Data Analytics from Boston University and CFA Level I, both January 2026; BS (Honours) in Mathematics and Computer Science from Chennai Mathematical Institute. Series 7 and Series 63. Python, R, SQL and a great deal of Excel.
That academic work led to papers in MDPI journals and articles in Stocks & Commodities, on DeFi perpetual futures, portfolio construction, and trading strategies in crude oil and Bitcoin.
Four years spent designing and teaching advanced maths and physics for students preparing for the International Junior Science Olympiad in India. Teaching is still the thing I am most enthusiastic about, along with motorsport.
What I'm thinking about
Whatever has hold of my attention: something I'm building, or something I want to understand properly. Some of it is code, some of it is maths, and some of it is a question I couldn't put down.
