Bernardo Ascensão
Founder of QFI Labs. Quantitative research, models and software for financial markets.
Every study starts with a testable question.
I read the literature, rebuild the experiments and record what holds and what does not.
Models trained for a defined task.
Language models for financial text and market algorithms, each with its own data and its own evaluation.
What matters is behaviour out of sample.
Parameter sensitivity, execution costs and market regimes are part of the test from the start.
