为啥美股可以一直涨，A股却只能震荡

Core Viewpoint - The article discusses the contrasting nature of the US and A-share markets, highlighting that the US market is a "blood-generating" market while the A-share market is a "blood-letting" market, primarily due to the different regulatory and operational frameworks in place [1][2]. Group 1: Market Dynamics - In 2022, the US market saw a significant inflow of capital through buybacks and dividends totaling $2 trillion, while only $208 million was raised through IPOs, indicating a stark imbalance in capital inflow and outflow [2]. - The A-share market has experienced a net capital outflow of approximately 1.3 trillion yuan annually from 2018 to 2022 due to various factors such as IPOs, private placements, and management fees, which far exceed the capital generated through dividends [2][3]. Group 2: Regulatory Environment - The regulatory framework in A-shares is designed to facilitate capital raising, with policies that encourage IPOs and other fundraising activities, often at the expense of existing shareholders [3]. - Recent measures introduced by the new leadership aim to address the capital outflow issue by limiting the number of IPOs and enhancing the quality of listings, which has led to a temporary bull market [3]. Group 3: Investment Behavior - The article suggests that the lack of short-selling mechanisms in the A-share market contributes to a predominance of bullish sentiment among investors, leading to market volatility [1][12]. - In contrast, the US market allows for short-selling, which can act as a stabilizing force, enabling investors to profit from declining stocks and thus contributing to a more balanced market environment [1][12]. Group 4: Broader Economic Implications - The article posits that the differences in market structures reflect broader economic ideologies, with the US market benefiting from capitalist principles that promote competition and innovation, while the A-share market is seen as more controlled and less dynamic [10][12]. - The implications of these market dynamics extend to the wealth distribution in both countries, with the US market's performance being closely tied to the fortunes of its large corporations, while the A-share market's structure may exacerbate wealth inequality among retail investors [9][18].
