Goldman Sachs: There is still further upward potential for the stock market before the end of the year.

The trading team of Goldman Sachs Group wrote in a report to customers, "We are now entering a seasonally biased period favorable to bulls, with a healthier position structure. As long as there are no major shocks, the market trend is not easily reversed. Although we do not necessarily expect a sharp rebound, there is still further upside potential before the end of the year."
