Warren Buffett’s Diversification
There are a couple of ways to look at the diversification of a portfolio. The first is to look at the number of stocks in a sector. It tends to highlight the sectors that have strong and stable businesses. See below for the number of stocks held in each sectors.
Mr. Buffett and his team carefully select all of their holdings. Here is a word of wisdom at the center of their stock selection process.
Price is what you pay. Value is what you get.
Please note that the sectors were identified as per the TSX. I like to use the same source for my sector tracking which is currently the TSX since it covers all the major North American stock exchange.
It’s clear that Warren Buffett and his team like the Financial Services sector. In fact, they like the credit cards companies since they hold all three major credit card companies. Consumer Defensive is the next big sector which include companies like Costco (NYSE:COST) or Wal-Mart (NYSE:WMT).
Consumer Cyclical and Communication Services are misleading as Berkshire Hathaway hold many different stocks from Liberty Global and Sirius Media. As for the Industrial sector, the addition of 3 airline companies to the portfolio has boosted the number of stocks for that sector.
The second way to look at diversification is by market value for each sector. If we follow the money, we can see that Buffett puts 80% of his money in 3 sectors; Financial Services, Consumer Defensive, and Technology. It is much more revealing when it comes to the type of businesses Buffett prefers. My investing strategy has also been leaning towards his top two sectors. It more easily fit my 7 rules of investing.
All in all, diversification is a matter of exposure and risk. It may or may not matter to you but the reason I track it is to understand my overall exposure to a sector and to also understand when a sector is out of favor as a way to systematically find opportunities.
Here is a quote to leave you with from one of the best investor of all times.
Wide diversification is only required when investors do not understand what they are doing.
