Group 1 - The relationship between the number of stocks invested and risk indicates that investing in only 2 stocks results in a volatility risk that is 2-3 times higher than the overall market risk [3][4] - Increasing the number of stocks to 20 leads to a risk that is 1/3 to 2/3 higher than the overall market volatility risk [4][5] - When the number of stocks reaches 50, the risk level aligns with the overall market risk, as many indices, such as the SSE 50 and STAR Market 50, start with 50 stocks [4][5] Group 2 - Further increasing the number of stocks beyond 50 does not significantly reduce risk, as seen in indices like CSI 300 and CSI 500, which include 300 and 500 stocks respectively, where the risk mirrors the market risk [5] - For most ordinary investors, utilizing fund portfolios to invest in dozens or even hundreds of stocks is a more prudent choice for effective diversification and risk management [5]
