Quandl (Nasdaq Data Link) Review

Premier source for financial, economic, and alternative datasets

Quandl, rebranded as Nasdaq Data Link after its 2018 acquisition by Nasdaq, is a leading platform for financial, economic, and alternative datasets used by quantitative analysts, hedge funds, and financial researchers. Founded in 2012, Quandl became the go-to aggregator of diverse financial datasets, offering both free public data and premium proprietary datasets through a single API. The platform covers traditional financial data—equity prices, company fundamentals, macroeconomic indicators—alongside alternative datasets that provide unique investment signals. Alternative datasets include satellite imagery, web traffic, sentiment analysis, geolocation data, supply chain monitoring, and credit card transaction aggregates. The Nasdaq acquisition has deepened the platform's financial data capabilities and extended its reach into institutional asset management. The API provides programmatic access to thousands of datasets in consistent JSON/CSV formats, with Python and R libraries for data science workflows. Premium datasets from institutional data providers like Preqin, FactSet, and specialized vendors are accessible through a single account. Data Lake capabilities enable enterprise clients to customize data delivery and storage. Nasdaq Data Link is particularly popular with quantitative investment firms, hedge funds building proprietary signals, and academic researchers studying financial markets. Its breadth of alternative data coverage and institutional pedigree make it a reference source in the quant investing community.
