Reviewed by: Rohit Tuli, CFA(R)

The U.S. stock market on Monday booked its fourth straight day of gains as S&P 500 and Dow Jones Industrial Average (DJIA) closed at new records. The rally in U.S. markets was fueled by continued hopes that the Federal Reserve wouldn't be in a rush to raise interest rates. The S&P 500 gained 0.38%, DJIA advanced 0.87%, and the Nasdaq moved up 0.34% at the close of the session. The European markets also ended the day in green, rising for the fifth session in a row, with Greek shares boosted by the Prime Minister's offer to bring pro-European independents into the government. The Asian stocks were mostly higher on Monday as steadiness in crude oil prices and the Russian ruble, along with the Federal Reserve's indication that it will take a slow approach to raising interest rates, lifted the market sentiments.
