By the end of the decade, the Dow Jones and the S&P 500 are expected to see considerable growth, per a new research from Yardeni Research.

Yardeni experts estimate the DJIA may hit 60,000, while they claimed the S&P 500 might top 8,000 by 2030.

According to Yardeni, the primary factor propelling the S&P 500's expansion is earnings per share (EPS), which has been rising consistently between 6 and 7 percent a year since the 1950s.

Under Yardeni's "Roaring 2020s" scenario, the S&P 500's earnings per share (EPS) may double to $400 by the end of the decade, and the index would surpass 8,000 with a price-to-earnings (P/E) ratio of 20.

Yardeni is hopeful despite the global concerns that exist right now.

In the past, geopolitical crises have frequently offered purchasing opportunities; yet, as they point out, the stock market had difficulties during the "crises-prone 1970s."

In addition, Yardeni cautions investors against letting their political beliefs sway their financial decisions, noting that markets often gain ground regardless of the president.

"The stock market tends to rise no matter who is in the White House and how much they've inflated the federal government's debt," the company stated.

Based on its research, since 1928, the S&P 500 has increased yearly on average by 7.3%, and gains have been further enhanced by dividends.

Yardeni points out that there are often more up years in the market than down years, and that February, May, and September have traditionally been the weakest months.
