Strength can not be felt everywhere, however. Buffett's largest holding, Coca-Cola (KO), has been a noticeable lag on the Berkshire Hathaway portfolio, causing it to slightly underperform the broad S&P 500. Shares of KO have dipped over 3% in the opening weeks of 2011.
An ETF such as the iShares S&P 100 Index Fund (IOO) may be a strong option for conservative-minded investors looking for a way to mimic Buffett's increasing taste for large and mega-cap companies.
Looking ahead, although Buffett appeared to have been in a selling mood over the past three months, it is unlikely that his view of the economic recovery has changed. As the markets remain on the healing path and investors take cautious steps back into equities, large, stable firms will likely continue to be a popular destination. A fund such as IOO instantly provides investors with exposure to a wide range of these leaders.Written by Don Dion in Williamstown, Mass.
