The number is closer to 40 securities but that graph should give ya the idea. The point of this isnt to call you diversified its to point out that you can effectively eliminate a lot of unnecessary risk that you take on by holding fewer securities. You can keep on doing what youre doing, and you may make out quite well, but you are bearing much more risk than you are being compensated for.
Interesting graph, but it doesn't answer my questions.
If I buy 50 stocks do they have to be 2% of the portfolio each to eliminate unnecessary risk?
What if I buy 50 stocks with the top 10 accounting for 70% of my holding, the next 10 accounting for 20%, and the remaining 30 sharing 10%?
What if I buy 50 stocks and one company accounts for 51%, while the remaining 49 companies account for 1% each?
Buffett's "Top 10 equity holdings" alone represent 83% of his portfolio. Are you saying he's taking unnecessary risk?
That graph certainly isn't applicable in all cases.
What if the stock you own is a conglomerate? (Ex: Berkshire Hathaway, Leucadia National)
Berkshire has businesses in insurance, mortgage company, jewelry, restaurants, natural gas, corporate jet firms, retail, encyclopedia, print media, foot wear/clothes. That doesn't even include the investment portfolio.
Do one really need to pick 1 of each in insurance, mortgage company, jewelry, restaurants, natural gas, corporate jet firms, retail, encyclopedia, print media, foot wear/clothes to reduce risk when they can just pick Berkshire Hathaway?
A person who is 100% in Berkshire vs. someone else who is 20% each in AMD, Citigroup, Hersheys, Wal-Mart, and Thornburg Mortgage.
Who do you think has less risk? Does person B have less risk simply because he has more securities? (keep in mind the 2 paragraphs above this when answering this question)
Disclosure: I don't own Berkshire directly, but Leucadia is the top equity holding representing 22% of the portfolio.
