The Nifty 50 was a group of the 50 most popular large cap stocks on the New York Stock Exchange in the 1960s and 1970s. The group included Walt Disney, Coca-Cola, Dow Chemical, IBM and McDonald's. Nifty 50 stocks were widely regarded as solid buy-and-hold equities and the companies in the group were characterized by consistent earnings growth and high P/E ratios. In addition, the Nifty 50 stocks were credited with propelling the bull market of the early 1970s.
Due to their marked stability, Nifty 50 stocks were viewed as "one-decision" picks because investors were told to buy and hold them forever. In February 2008, Wall Street giant UBS devised the New Nifty 50, an expanded version of the list, which now includes international companies like Toyota, Samsung, Nokia and Swatch. The inclusion of international companies on the New Nifty 50 allows investors to take advantage of the solid returns and stability of companies in the UK, Japan and some European countries.
