The role of investment advisors has become increasingly significant in guiding retail investors through complex financial markets. This study investigates the influence of investment advisors on the investment decisions of retail investors in Bengaluru, a growing financial hub in India. Using a combination of primary data (structured questionnaires from 200 retail investors) and secondary data (existing literature and regulatory reports), the study evaluates how advisory services impact investor behavior, risk appetite, portfolio choices, and financial literacy. Findings indicate that trust, communication quality, and risk profiling are key determinants of investors’ willingness to act upon advisor recommendations and to endorse them to peers. Demographic variables such as age and income do not significantly moderate recommendation behavior. The study offers actionable insights for advisors, investors, and regulators to enhance advisory efficacy, investor protection, and financial literacy in urban India.
