According to Odaily Planet Daily, Goldman Sachs published a report saying that it expects the S&P 500 index to rise to 6,500 points by the end of this year, mainly driven by corporate profit growth. It is estimated that earnings per share will increase by 11% this year and 7% next year.

The price-to-earnings ratio is expected to remain at about 21.5 times by the end of the year. The S&P 500's total return last year was 25%, the second consecutive year of returns exceeding 20%.

Nearly half of last year's annual returns came from just five stocks: Nvidia, Apple, Amazon, Alphabet and Broadcom.
