This document analyzes the effect of financial knowledge on investment decisions of 200 investors from Gandhinagar District in India. It finds that urban investors have significantly higher average financial knowledge scores than rural investors, based on their answers to questions testing understanding of financial terms, risk, return, and investment avenues. A questionnaire was used to collect data on demographics, financial knowledge, perceptions of risk and return of different investments, and actual investment decisions. The findings suggest that greater financial knowledge is correlated with more rational investment decisions based on risk-return analysis rather than just opinions of others.
