The Role of Cloud-Based Vector Databases and Retrieval Augmented Generation (RAG) for Generative AI in Financial Markets Analysis

Prakash, Siva (2025) The Role of Cloud-Based Vector Databases and Retrieval Augmented Generation (RAG) for Generative AI in Financial Markets Analysis. World Journal of Advanced Engineering Technology and Sciences, 15 (3). pp. 1609-1618. ISSN 2582-8266

This scholarly article examines the transformative role of cloud-based vector databases and Retrieval Augmented Generation in enhancing generative artificial intelligence for financial markets evaluation. The convergence of these technologies creates powerful systems that overcome the constraints of standalone large language models by grounding outputs in specific, relevant financial information. Vector databases such as Pinecone, Weaviate, and Milvus enable efficient storage and retrieval of high-dimensional embeddings representing complex financial data, while RAG frameworks significantly improve accuracy, reduce hallucinations, and maintain temporal relevance in rapidly changing markets. Applications span semantic search of financial documents, enhanced sentiment assessment of market news, automated report generation, and more reliable financial forecasting. The advantages include improved accuracy and reliability, greater scalability and computational efficiency, enhanced explainability essential for regulatory compliance, and superior adaptability to changing market conditions. Despite significant benefits, implementation requires addressing challenges related to data security, regulatory compliance, technical integration, knowledge management, and organizational change. Financial institutions following best practices can leverage these technologies to gain deeper market insights and make more informed strategic decisions in increasingly complex global markets.
