The stock market plays a very important role in an economy through the efficient, safe and operative transfer of the available capitals from those who saved to businesses. The global economic shock caused by the COVID-19 pandemic has accentuated long-term structural challenges in the corporate sector and on the stock market, and Romania needs a strong stock market that can finance the development needs of Romanian companies. The Bucharest Stock Exchange is the main pillar of the Romanian stock market that offers an alternative financing to mature companies, which can attract capital on the Main Market, as well as to start-ups and SMEs for which the AeRO market was created. On October 11, 2021, BVB launched BET AeRO (BUCHAREST EXCHANGE TRADING AeRO INDEX), the first index of the AeRO market that reflects the evolution of the representative companies on the AeRO market selected according to liquidity and free-float capitalization criteria.
