Market observers believe high volatility and expensive valuations have kept Indian stocks away from Buffett’s radar. The portfolio of Buffett, the world’s third richest person with a net worth of more than $52 billion, consisted of 44 stocks across the world as of March 31, 2007. These included soft drink maker Coca-Cola, Johnson and Johnson and Procter and Gamble, Wal-Mart, Nike, ConocoPhillips and financial services provider American Express.
