WHAT WARREN BUFFETT SAYS ABOUT DIVERSIFICATION


There is a seeming disparity of views between Graham and Buffett on diversification. 
  • Benjamin Graham was a firm believer, even in relation to stock purchases at bargain prices, in spreading the risk over a number of share investments. 
  • Warren Buffett, on the other hand, appears to take a different view: concentrate on just a few stocks.

WHAT WARREN BUFFETT SAYS ABOUT DIVERSIFICATION

In 1992, Buffett said that his investment strategy did not rely upon spreading his risk over a large number of stocks; he preferred to have his investments in a limited number of companies.
‘Many pundits would therefore say the [this] strategy must be riskier than that employed by more conventional investors. We disagree. We believe that a policy of portfolio concentration may well decrease risk if it raises, as it should, both the intensity with which an investor thinks about a business and the comfort-level he must feel with its economic characteristics before buying into it.’


NO REAL DIFFERENCE BETWEEN BENJAMIN GRAHAM AND WARREN BUFFETT

The differences between Graham and Buffett on stock diversification are perhaps not as wide as they might seem. 
  • Graham spoke of diversification primarily in relation to second grade stocks and 
  • it is arguable that the Buffett approach to stock selection results in the purchase of quality stocks only.


BERKSHIRE HATHAWAY HOLDINGS

In addition, consideration of Berkshire Hathaway holdings in 2002 suggests that although Buffett may not necessarily believe in diversification in the number of companies that it owns, its investments certainly cross a broad spectrum of industry areas. They include:
  • Manufacturing and distribution – underwear, children’s clothing, farm equipment, shoes, razor blades, soft drinks;
  • Retail – furniture, kitchenware
  • Insurance
  • Financial and accounting products and services
  • Flight operations
  • Gas pipelines
  • Real estate brokerage
  • Construction related industries
  • Media
