Why does the US stock market continue to rise? J.P. Morgan strategists say this factor may be the key driver.

According to the Zhixin Financial APP, since the global financial crisis in 2008, the US stock market has continued to steadily rise. The profit margins of large American companies have been constantly expanding, and profit volatility has significantly decreased, providing solid support for the stock market's rise. The global research team of US banks pointed out that companies in the S&P 500 index have almost completely eliminated floating-rate debt, making their balance sheets healthier. At the same time, tech giants such as Microsoft (MSFT.US) and Apple (AAPL.US) have risen, not only profoundly changing the global economic landscape but also creating huge profits.
