Over the past few years the stock market has experienced a rapid inflow of retail investors. This is due to a number of factors: the development of technologies and emergence of clear and transparent services, increased financial literacy of the population, and lower interest rates on bank deposits. Last year, the Moscow Exchange saw a record inflow of retail clients. Alibabas money market fund, Yue Bao, is one of the biggest in the world. Robinhood, the company that provides retail investors with a clear and simple interface with the stock market, is among the highest-valued fin-tech start-ups in the world. Will retail investors become a catalyst for stock market development and what are the growth prospects for this segment? How can the qualitative growth of this segment be ensured and how can a balance be achieved between risks and profitability?
