According to CNBC, investors heavily exposed to S&P 500 funds are being urged to diversify as information technology now accounts for about 37% of the index and communications pushes the total to almost 50%. Mitch Goldberg of ClientFirst Strategy said the index is no longer broadly balanced, while Todd Rosenbluth of TMX VettaFi said investors with too much S&P 500 exposure may be missing stronger gains in small-cap and international stocks this year. Ankur Patel of Ellevest said developed international and emerging markets trade at roughly 10 to 15 times forward earnings, compared with about 20 times for the S&P 500, and Neena Mishra of Zacks Investment Research said shorter-term government bonds, dividend-growth ETFs and gold can help reduce volatility.
